This product has a theoretical yield of 43.7 Cubic FT. Slow Rise (SR) is a multi-purpose polyurethane foam. Handi-Foam SR cures tack free in 60-90 seconds, is cuttable in 5-10 minutes and cures within 1 hour. Handi-Foam SR Products have a free-rise density of 1.75 lb. per cubic foot (28kg per cubic meter) and an in-place density of 2.0 lb per cubic foot (32 kg per cubic meter) and carry an R-value of 6.2 per inch. Optimum chemical temperature must be between 75°-85° F. The cured foam can resist heat and cold -200° to +200° F. However, cured foam is not resistant to UV rays (sunlight) unless painted or stained. Cured foam can be trimmed, sanded and/or painted. Handi-Foam SR systems meet the Coast Guard Specification Requirements for flotation in Title 33 Code of Federal Regulations, Paragraph 183.114. Handi-Foam SR is formulated to slowly rise, fill and insulate large enclosed spaces and blind cavities. However, there are some considerations which will effect mold pressure and how efficiently the mold is filled. They are application shot time, orientation and bracing, mold size and mold venting.
