SURFACE PREPARATION
Surfaces to receive NATURAL -THERM® 0.50 PCF must be
clean and dry, free of dirt, oil, solvent, grease, loose par!
ticulates, frost, ice and other foreign matter which could in j
hibit adhesion. Moisture content and surface conditions
of substrate are critical to adhesion of NATURAL -THERM®
0.50 PCF and need to be verified by installing contractor
in small test areas before proceeding with full applicationl.
Plywood, OSB, and lumber shall not have greater than 18%
moisture content. Generally, a primer is not required for
these surfaces. On substrates where the moisture content
cannot be determined or exceeds 18%, a suitable primer
is recommended. Adhesion spray tests may be performed
with insulating foam and the interface line checked upon
cure for good cell structure and adhesion. Warming of these
surfaces during winter conditions may increase adhesion.
CMU, structural and poured -in -place concrete must have a mini
mum 28-day cure and moisture content below 18%. Residential
footings, stem -walls, and basements generally do not require
priming. Commercial controlled atmosphere structures, cold
storage, and freezer buildings require an appropriate primer to
insure adequate adhesion where curing agents may have been
used. Generally use, a two -component epoxy primer designed
to seal and provide adhesion to concrete surfaces. Contact a
Natural Polymers representative for suggested primer options.
Painted Steel, galvanized steel, and aluminum panels: check sur-
faces for mill oil used in the manufacturing process and moisture
condensate. All oil must be removed and the surface clean and dry
before priming. Washed and dry painted steel panels may not re-
quire priming. All aluminum and galvanized panels must be primed
using Cardinal4860-420 or Sherwin Williams® DTM Wash Primer.

static proportioner pressure setting of 1200 psi. Older equipment
may be upgraded with "Arctic Booster Pack" heaters or minimum
E-20 proportioners are required to adequately pre -heat the com
ponents. Spray guns such as; D-gun, GAP gun, GX-7, Fusion gun,
or Probler guns fitted with smaller output tips (15-18 lbs./min.)
for better spray control for stud wall applications at recommend-
ed processing temperatures are recommended.
** Complete cure will depend on temperature, humidity and
degree of ventilation. Complete cure usually occurs within 24-72
hours.
PRODUCT APPLICATION:
Natural -Therm" 0.50 PCF should only be applied to approved
substrates in 1-inch to 6-inch lifts. This procedure is in accor-
dance with the manufacturer's recommendations detailed in the
application manual.
RECOMMENDED SUBSTRATE TEMPERATURES
Minimum 32°F
Maximum 1207
For applications below 32°F, Natural Polymers, LLC technical
personnel should be consulted. Flash passes should be avoided.
CLIMATIC CONDITIONS & HUMIDITY
Moisture in the form of rain, dew, frost can seriously affect the
quality and adhesion of the NATURAL -THERM® 0.50 PCF to the
substrate or itself. Natural Polymers does not recommend the
spraying of this system when the relative humidity (RH) exceeds
85% or within 57 of the dew point. When heating the interior
of a building the relative humidity can change dramatically and
should be constantly monitored.

RECOMMENDED PROCESSING TEMPERATURE
RANGE:
Component A 100-135°F
Component B 100-135°F
Hose 100-135°F
Processing temperatures are critical to achieve viscosity to allow
balanced pressure during spraying. Balanced chemical output
pressures are important to producing good mix. Foam output
pressures greater than 50 psi differential indicate either improp
er chemical temperatures, or worn gun/packing parts. Unequal
pressures will cause poor chemical mixing through the module
and uneven backpressure. A critical requirement for good spray
mixing requires appropriate tip/ module sizing to the proportion
er and adequate heating capacity. Unequal pressure (>50 psi)
can cause excessive pump wear.
Equipment:
The proportioning equipment shall be manufactured specifically
for heating, mixing, and spray application of polyurethane foam
and be able to maintain 1:1 metering with a +2% variance and adL
equate main heating capacity to deliver heated and pressurized
materials up to 150"F. Heated hose must be able, to maintain pre
set temperatures for the full length of the hose. Minimum 2:1 on
the A side and 1:1 on the B side ratio feeder pumps are required
to supply stored materials through minimum %:-inch supply hot;
es. Pressurized and heated tanks systems may be used if sized
appropriately to provide adequate flow at maximum operating
capacity and temperatures. i
Guns such as D-gun, Gap Pro, Fusion -gun, Probler with tip size
approximately 16 lbs./min are suitable for most residential appli;
cations. Commercial cold storage, freezer,applications, and large
metal buildings may utilize higher output guns.
Spraying:
Thin "flash passes" to very cold surfaces are not recommended.
Thin passes (1/4" or less) should be avoided. They may result in
reduced yield and loss of adhesion. It is recommended that the
total design thickness be completed each day.
This spray system should be applied in uniform minimum pass
thickness of 1-inch, maximum pass thickness 6-inches. Applica-
tion temperatures below 32"F may require reduction in single
pass application thickness. Additional thickness may be ap-
plied after a note no waiting period for %: pcf foams they cool
down fast you may spray multiple pass over the same lift. Yield
and in -place -density is dependent upon the temperature of the
substrate, ambient air temperature, gun speed application, gun
tip size, and the output of the proportioning unit. NATURAL -
THERM® 0.50 PCF is designed to provide maximum yield when
sprayed in 6" thick passes. Excessive pass thickness can reduce
density and physical properties, and cause local overheating and
possible fire.
Re -circulating the 'B' component is not recommended if the
drum temperature is below 65°F. The re -circulating of the 'B'
component can be used as a means of warming the material. If
re -circulating the 'B' component the material must be agitated
with a mixer while the material is being re -circulated. Polyure-
thane foams will burn when exposed to fire. Caution during ap-
plication must be observed with signs posted for other trades,
"Caution Combustible Insulation, No Welding or Hot Work Al-
lowed". On a daily basis remove all debris and shavings from the
job site leaving a clean work area. In freezing conditions [below
32°F], jobsite air temperature must be maintained above 32 de-
grees F. during the cure cycle so extreme temperature drops to
the curing [green) foam is not experienced.
Job Site Ventilation:
During SPF application a minimum of 30-60 ACH is recommend-
ed. Cross ventilation is required with negative pressure in the
spray area and exhaust to a secured empty area. For increased
ventilation rates a commercial unit is recommended. For more

Precautions:
Read and understand the Safety Data Sheet (SDS) for this product
before use. The numerical flame spread and all other data pre-
sented is not intended to reflect the hazards presented by this
or any other material under actual fire conditions. Polyurethane
foam may present a fire hazard if exposed to fire or excessive
heat (i.e. cutting torches). The use of polyurethane foam in in-
terior applications on walls or ceiling presents an unreasonable
fire risk unless protected by an approved fire resistant thermal
barrier with a fire rating of not less than 15 minutes. A UBC or
IRC code definition of an approved "thermal barrier" is a material
equal in fire resistance to %2" gypsum board. Each firm, person,
or corporation engaged in the use, manufacture, or production
or application of the polyurethane foams produced from these
resins should carefully examine the end use to determine any po-
tential fire hazard associated with such product in a specific use
and to utilize appropriate precautionary and safety measures.
Consult with local building code officials and insurance agency
personnel before application.

Storage & Shelf Life
Both components should be stored in their original containers
and away from excessive heat and moisture, especially after
the seals have been broken or some materials have been used
Drums must be stored indoors and jobsite tanks maintained be-
tween 50°F and 907. Containers should be opened carefully to
allow any pressure buildup to be vented safely while wearing full
safety protection. Excessive venting of the 'B' component may
result in higher density foam and reduced yield. Materials stored
at temperatures below 50°F will increase viscosity and some ap-
plication equipment may not reach adequate spray temperature
set points. Supply pumps and hoses must be sized to provide
adequate supply when materials are cold and at a higher viscos-
ity. Shelf Life: Excessive low or high temperatures may decrease
shelf life. When stored in the original unopened container at
50°F-90°F, the shelf life of the "Part B" component is six months.
Temperature above 90"F decreases the shelf life. The "Part A"
component has a shelf life of 12 months in unopened containers
when stored at 50°-90°F.

Summer & Winter Closed Cell Spray Foam Insulation
SURFACE PREPARATION
Surfaces to receive NATURAL -THERM® 2.0 PCF must bi
clean and dry, free of dirt, oil, solvent, grease, loose par
ticulates, frost, ice � and other foreign matter which could in
hibit adhesion. Moisture content and surface condition:
of substrate are critical to adhesion of NATURAL -THERM°
2.0 PCF and need to be verified by installing contractor it
small test areas before proceeding with full application
Plywood, OSB, and lumber shall not have greater than 18%
moisture content. Generally, a primer is not required for
these surfaces. On substrates where the moisture content
cannot be determined or exceeds 18%, a suitable primer,
is recommended. Adhesion spray tests may be performed
with insulating foam and the interface line checked upon'
cure for good cell structure and adhesion. Warming of these
surfaces during winter conditions may increase adhesion.;
CMU, structural and poured -in -place concrete must have a mini;
mum 28-day cure,and moisture content below 18%. Residential;
footings, stem -walls, and basements generally do not require'
priming. Commercial controlled atmosphere structures, cold
storage, and freezer buildings require an appropriate primer to
insure adequate adhesion where curing agents may have been
used. Generally use, a two -component epoxy primer designed
to seal and provide adhesion to concrete surfaces. Contact al
Natural Polymers representative for suggested primer options.
Painted Steel, galvanized steel, and aluminum panels: check sur-
faces for mill oil used in the manufacturing process and moisture,
condensate. All oil must be removed and the surface clean and dry,
before priming. Washed and dry painted steel panels may not re
quire priming. All aluminum and galvanized panels must be primed,
using Cardinal 4860-420 or Sherwin Williams® DTM Wash Primer.,

or Probler guns fitted with smaller output tips (15-18 lbs./min.)
for better spray control for stud wall applications at recommend-
ed processing temperatures are recommended.
** Complete cure will depend on temperature, humidity and
degree of ventilation. Complete cure usually occurs within 24-72
hours.
PRODUCT APPLICATION:
Natural -Therm" 2.0 PCF should only be applied to approved sub-
strates in 1-inch to 3-inch lifts. This procedure is in accordance
with the manufacturer's recommendations detailed in the appli-
cation manual.
RECOMMENDED SUBSTRATE TEMPERATURES
Winter Blend 20'F - 65"F
Summer Blend 55'F -120°F
For applications below 20°F, Natural Polymers, LLC technical
personnel should be consulted. Flash passes should be avoided.
CLIMATIC CONDITIONS & HUMIDITY
Moisture in the form of rain, dew, frost can seriously affect the
quality and adhesion of the NATURAL -THERM® 2.0 PCF to the
substrate or itself. Natural Polymers does not recommend the
spraying of this system when the relative humidity (RH) exceeds
85% or within 5°F of the dew point. When heating the interior
of a building the relative humiditycan change dramatically and
should be constantly monitored.

Summer & Winter Closed Cell Spray Foam Insulation
RECOMMENDED PROCESSING TEMPERATURE
RANGE:
Component A 115-130°F
Component B 115-130°F
Hose 115-130°F
Processing temperatures are critical to achieve viscosity to allow
balanced pressure during spraying. Balanced chemical output
pressures are important to producing good mix. Foam output
pressures greater than 50 psi differential indicate either improp-
er chemical temperatures, or worn gun/packing parts. Unequal
pressures will cause poor chemical mixing through the module
and uneven backpressure. A critical requirement for good spray
mixing requires appropriate tip/ module sizing to the proportion-
er and adequate heating capacity. Unequal pressure (>50 psi)
can cause excessive pump wear.
Equipment:
The proportioning equipment shall be manufactured specifically,
for heating, mixing, and spray application of polyurethane foam
and be able to maintain 1:1 metering with a +2% variance and ad-
equate main heating capacity to deliver heated and pressurized
materials up to 150°F. Heated hose must be able to maintain pre-
set temperatures for the full length of the hose. Minimum 2:1 on
the A side and 1:1 on the B side ratio feeder pumps are required
to supply stored materials through minimum %:-inch supply hos-
es. Pressurized and heated tanks systems may be used if sized
appropriately to provide adequate flow at maximum operating
capacity and temperatures.
Guns such as D-gun, Gap Pro, Fusion -gun, Probler with tip size
approximately 16 lbs./min are suitable for most residential appli-
cations. Commercial cold storage, freezer applications, and large
metal buildings may utilize higher output guns.
Spraying:
Thin "flash passes" to very cold surfaces are not recommended.
Thin passes (1/4" or less) should be avoided. They may result in
reduced yield and loss of adhesion. It is recommended that the
total design thickness be completed each day.
This spray system should be applied in uniform minimum pass
thickness of 1-inch, maximum pass thickness 3-inches. Applica-
tion temperatures below 20°F may require reduction in single
pass application thickness. Additional thickness may be applied
after waiting 10-20 minutes between passes until reaching de-
sired thickness. Yield and in -place -density is dependent upon
the temperature of the substrate, ambient air temperature, gun
speed application, gun tip size, and the output of the propor-
tioning unit. NATURAL -THERM® 2.0 PCF is designed to provide
maximum yield when sprayed in 3 inch passes. Excessive pass
thickness greater than 3 inches can reduce density and physical
properties, and cause local overheating and possible fire.
Job Site Ventilation:
During SPF application a minimum of 30-60 ACH is recommend-
ed. Cross ventilation is required with negative pressure in the
spray area and exhaust to a secured empty area. For increased
ventilation rates a commercial unit is recommended. For more
detailed information, please visit http://polyurethane.american-
chemistry.com/Spray-Foam-Coalition/Guidance-on-Ventilation-

Precautions:
Read and understand the Safety Data Sheet (SDS) for this product
before use. The numerical flame spread and all other data pre-
sented is not intended to reflect the hazards presented by this
or any other material under actual fire conditions. Polyurethane
foam may present a fire hazard if exposed to fire or excessive
heat (i.e. cutting torches). The use of polyurethane foam in in-
terior applications on walls or ceiling presents an unreasonable
fire risk unless protected by an approved fire resistant thermal
barrier with a fire rating of not less than 15 minutes. A UBC or
IRC code definition of an approved "thermal barrier" is a material
equal in fire resistance to %" gypsum board. Each firm, person,
or corporation engaged in the use, manufacture, or production
or application of the polyurethane foams produced from these
resins should carefully examine the end use to determine any po-
tential fire hazard associated with such product in a specific use
and to utilize appropriate precautionary and safety measures.
Consult with local building code officials and insurance agency
personnel before application.
When using fuel fired heating units the exhaust must be vented
directly outdoors to prevent unsafe carbon monoxide condi-
tions in the work area. Electric heating units are preferred. All
heaters must be turned off before the application of foam begins.
Natural Polymers Technical Personnel should be consulted in all
cases where application conditions are marginal.
Worker exposure hazards - Both Components A and B can cause
severe inhalation and skin sensitization. For interior applica-
tions: full body protection required. For more information, visit

Storage & Shelf Life
Both components should be stored in their original containers
and away from excessive heat and moisture, especially after
the seals have been broken or some materials have been used!
Drums must be stored indoors and jobsite tanks maintained be-
tureen 50°F and 907. Containers should be opened carefully to
allow any pressure buildup to be vented safely while wearing full
safety protection. Excessive venting of the 'B' component may
result in higher density foam and reduced yield. Materials stored
at temperatures below 50"F will increase viscosity and some ap'
plication equipment may not reach adequate spray temperature
set points. Supply pumps and hoses must be sized to provide
adequate supply when materials are cold and at a higher viscos;
ity. Shelf Life: Excessive low or high temperatures may decrease
shelf life. When stored in the' original unopened container at
50°F-90°F, the shelf life of the "Part B" component is six monthsl.
Temperature above 90'F decreases the shelf life. The "Part A"
component has a shelf life of 12 months in unopened containers
when stored at 50°-90°F.

RECOMMENDED APPLICATION INSTRUCTIONS
Substrate Preparation
To ensure best results, the surface to be sprayed must be free of all grease, oil,
moisture, loose particles, or other foreign matter which might adversely affect the
adhesion of the foam to the substrate. To assure proper adhesion to existing foam
substrates, coatings which hinder bonding, such as silicone, must be completely
removed prior to spraying. Insulation or sheathing with aluminum foil facers is
not considered to be a suitable substrate. Metal substrates should be cleaned by
means of commercial sandblasting, wire brush, or chemical treatment to remove
scale or rust. Special attention is to be given to galvanized steel, aluminum and
other non-ferrous metal surfaces. Such surfaces require an acid wash, a thorough
water rinse, and then complete drying prior to priming. Primer coats are recom-
mended for all iron, steel, aluminum, and galvanized steel substrates. A vapor
barrier will be necessary when it is believed that vapor transmission through the
substrate will cause an accumulation of moisture. Only qualified, experienced
spray applicators should determine the suitability of a substrate for spraying.
Climatic Considerations
When choosing the specific reactivity of NATURAL -THERM" 3.0 Series for a par-
ticular application, climatic conditions must be anticipated. To ensure proper foam
performance, all substrates to be sprayed must be dry (i.e., the application should
not take place in high moisture conditions such as rain, fog, mist, frost, or high
humidity, e.g., >85%RH). Under high wind conditions (>12 mph), problems with
texture, cure, and overspray will likely be experienced. All foams polyurethane
foams should be protected from direct prolonged contact from sunlight. To pro-
tect exposed foam surfaces from prolonged ultraviolet degradation and moisture
attack, the application of a coating is required immediately after the foam has
cured. A dean, dry foam surface is required for adequate coating adhesion.
Processing Recommendations
The processing equipment to be used must maintain, at all times, equal process-
ing ratios (50/50) by volume. The spray gun must provide thorough and intensive
mixing of the two components at all processing throughputs. Optimum compo-
nent pressures and temperatures will vary from machine to machine. Typically,
higher mixing pressures will provide improved yield, cell structure and physical
properties. A 2-to-l-transfer pump in the B-Component drum is recommended
in colder weather conditions (<607) where increased component viscosity may
limit the supply of material in the metering pump. During spray applications of
polyurethane foam systems, whether outdoors, indoors, or in a spray booth, pos-
itive -pressure air -supplied masks or hoods are mandatory. The following equip-
mentset-ups are recommended for processing NATURAL -THERM" 3.0 Series spray
foam systems. Natural-Therm''3.0 PCF has been evaluated by SGS USTC 1127557-
3 in accordance to the ASTM tests listed in this sheet.
