What new concerns does the closed cell foam with the 245 freon present?
You want to keep the 'B' side temp around 50-70F. When preheated the material, turn the heater on the 'B' side down to 70F. Do not preheat the drums with material over 70F or the material will froth and freon will escape. Also it is better to use stick pumps rather than diaphragm pumps when working with closed cell foam. Although using diaphragm pumps will work if the material does not exceed 70F.
How do you clean cured foam out of the air passages inside the gun handle when you crossover the gun?
Use clean out kit p/n 248969 to drill out air passages inside gun handle
How do I keep my material under 70F in a 80-90F day?
We recommend using an air conditioner to cool the truck/trailer or material storage.
Endisys also can supply chillers and glycol reservoir bulk tanks that are also able to accurately manage the material temperatures.
What solvent do you recommend to use to dissolve cured foam from guns?
Brulin Safety Strip or boil Prestone antifreeze.
