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. PROCESSING CHARACTERISTICS Machine Mix at recommended processing temperatures Cream Time 1.5 seconds Tack Free Time 6.5 seconds Initial Cure Time <1 Hour** The nominal physical properties reported were'achieved using 'a Graco H25 Proportioner and Fusion gun with #02 module with 'a 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. INITIAL PROCESSING RECOMMENDATIONS: (Ambient) 30-65'F 65-80°F >807 Component A 135°F 125°F 118°F Component B 135'F 1257 1187 Hose 1357 125°F 118"F These temperatures are typical of those required to produce acceptable product using conventional Gusmer or Graco equip- ment. It is the responsibility of the applicator to determine the specific temperature settings to match the environmental condi- tions and specific spray equipment. www.naturalpolymerslic.com Natural Polymers, LLC ,Natural . mail@naturalpolymersllc.com `po�'yrr,ers,� 4N325 Powis Road Phone: 888-563-3111 f West Chicago, IL 60185 Natural -Thermo _A�030 PCF OpLn Cell Spray Foam 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.

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. www.naturalpolymersilc.com aNatural Polymers, LLC ,, Natural., _ mail@naturalpolymerslic.com �Po[y:rers, 4N325 Powis Road Phone: 888-563-3111 West Chicago, IL 60185 When using fuel fired heating units the exhaust must be vented directly outdoors to prevent unsafe carbon monoxide condi-I tions-in the work area. Electric heating units are preferred. A111 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.

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.

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.

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.

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.

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.

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.
