This chart is a starting guide to set temperatures based on environment, mixing chamber size. Adjustments should be made to account for substrate temp/type, hose insulation condition, speed of sprayer, wind factor, etc. A smaller mixing chamber, like a 4242, will give you the best quality foam at optimal speed-to-yield ratio.

- Processing Instructions
Agitation - Do not agitate.
Drum Temperatures & Recirculation - Do not recirculate. Starting chemical temperatures in the drums should be between 55°F-75°F for both the A & B-drums. Use laser thermometer or inlet temp gage to measure drum temp (A-Drum should never be warmer than B-Drum). If drum is below 55°F, then slowly raise temp with warming blanket or heated storage. Never super-heat with portable heater. If drum is too hot then blowing agent will boil-off.
Substrate Condition - Substrate must be clean, dry, and moisture content 5°F above dew point. When substrate temperature is below 45°F, pre-heat building. When heating with portable heaters, if concrete or metal substrate only heat to 50°F, otherwise condensation may form. Never use portable propane heaters. When substrates temps are above 80°F and below 30°F, switch to summer or winter blends accordingly.
Contamination - B-Side is sensitive to contamination from other products. Never combine different products. Transfer pumps must be properly cleaned between product.
Spray Technique - Spray up-and-down approx 18” from surface. The further away you spray, the colder the chemical will be when reaching substrate. Layering will reduce yield, but make smoother. When substrate temp is below 35°F, may need 1/2” priming layer to improve adhesion.
Metal | Concrete Applications - When applying on metal or concrete you may need a 1/2” priming layer. Increase temperatures by 2-5°F to account for heat loss from these surfaces.
Max | Min Pass Thickness - Max pass thickness is 2”. If the foam is applied too hot or too thick, will overheat foam and cause burnt/ ”fishy” odor, result in future shrinkage, or possibly lead to fire hazard (including spontaneous combustion). 2nd layer may be applied after 1st layer is hard to the touch.
Proper Temperature Settings - As a general rule of thumb, the hose temperature is the most important setting and should be set first. The A-side is set 2-5°F higher than the hose. The B-Side is set 2-5°F higher than the A-Side. Important: Core temp should never exceed 250°F.
† Heated Hose - A poorly insulated hose may not be able to maintain adequate hose heat and drastically change required temp settings on primary heaters. Never Increase hose temp above 145°F - you can burn the hose.
Maximizing Yield - Dozens of factors affect yield, but properly dialing in temps and # of layers is critical. Start temperatures cold enough that the foam sags slightly, then increase temps 5°F at a time until sagging stops. Ideal safe core temp should be 230-240°F. Many thin layers will reduce yield significantly.
**Pressure Settings - Air pressure settings to the Gun for 01 mix chamber should be at 100psi, for 02 at 125psi. Higher fluid pressure settings create more mist and require greater distance from the cavity, resulting in more overspray. Higher pressure will generally lower yield. As a rule-of-thumb, you should practice spraying as close to 1000psi as practical.
- Troubleshooting Guide
Delamination - If foam delaminates from substrate, it may be from cold substrate. Apply an initial 1/2” priming layer to improve adhesion. Another cause may be excess moisture in substrate; try reducing A-side temps by 5-7°F to reduce Iso reactivity. Spraying over uncured foam may also cause delamination.
Blistering - If foam creates voids and blisters behind foam, it may be from too much moisture in substrate. Apply a sacrificial mist layer to the substrate, then apply regular pass as normal. IF spraying on metal and blisters form, try increasing thickness of initial pass (no less than 1/2”).
Elongated Cell Structure - If the foam has stretched or elongated cells, then it is likely too hot. Try reducing all temps by 5°F.
Large Cell Structure - If the foam has consistently large cell structure,then the B-side resin may be contaminated with open-cell resin.
Crunchy or Gummy - If foam is crunchy and amber in color, then foam may be Iso rich and off-ratio. If “gummy” consistency, then foam may be Resin rich. Check equipment. Cured foam should be snappy in consistency when broken apart.
Chalky | Brittle - Too hot. Lower all heaters by 5-7°F. If problem does not resolve, lower temperature by another 5°F, and repeat.
Curing Too Fast - If the closed-cell is curing too fast then it is too hot and could result in future cracking. Lower temperatures by 3°F or as needed.
Curing Too Slow - If the closed-cell is curing too slow then it is too cold and you may see a narrow spray pattern. Raise temperatures by 5-7°F or as needed.
Gun is Clogging Often - If the mixing chamber needs constant cleaning, then foam may be too hot. Lower temperatures by 3-5°F or as needed. Also check gun air settings.
Poor Yield - Check temp settings. If temperatures are dialed-in too cold, then lack of heat will generate poor chemical reactivity & poor yield (See “Proper Temperatures Settings” & “Maximizing Yield” under Processing Instructions). Avoid too many thin layers. Check chemical expiration.
Pulls Away From Studs - If pulls away or “shrinks” from studs over time, then foam was applied too hot, too thick, or second layer applied over hot foam.
Important - Minimum drum temperature of 55°F is necessary to bring viscosities of A&B in alignment to prevent off-ratio foam and increase yield; setting chemical temperatures above recommendations may result in B side frothing. If the B-drum is over 85°F, then the blowing agent may boil and cause imbalance pressure in proportioner.
Frothing - UPC 1.7 contains a dissolved blowing agent. If the B-side drum is overheated or excessively agitated, the chemical may froth out. Using regular formula in summer temps may also contribute to frothing or imbalance pressure in proportioner.
- Cautions and Recommendations
UPC 1.7 is not designed for use as an exterior roofing system. UPC 1.7 is designed for installation in most standard construction configurations using common materials such as, concrete, metal, and wood products. The foam should not be used when the continuous service temp of the substrate is >180°F. Foam plastic installed in walls or ceilings may present a fire hazard unless protected by an approved, fire-resistant thermal barrier with a finish rating of not less than 15 minutes as required by building codes. Rim joists/ header areas in accordance with the IRC® and IBC®, may not require additional protection. Foam plastic must also be protected against ignition by code-approved materials in attics and crawl spaces or as code approved alternatives apply.
As with all SPF systems, improper application techniques should be avoided and any defective product replaced with properly installed materials. Examples of improper application techniques include but are not limited to, excessive application thickness, off-ratio material and spraying into or under rising liquid foam. Additionally, off-ratio materials can result in offensive odors that may not dissipate. It is the responsibility of the applicator to understand how their equipment works.
- Vapor Retarder
When installed at a minimum of 1.5-inch UPC 1.7 is considered a Class II vapor retarder. Consult with local code officials for specific requirements Climate zone tables are available in current IBC® and IRC® publications.
