Versatile, Fast Curing — FROTH-PAK Polyurethane Spray Foam System

FROTH-PAK is a two-component polyurethane spray foam that comes in both portable kits and refillable tanks. It is available in multiple densities and is ideal as an insulator or air-sealant. 

FROTH-PAK can be used to fill cavities, wall and floor penetrations, cracks and expansion joints, cold storage facilities and refrigerated trailers. 

FROTH-PAK can also be used to repair spray-applied polyurethane roofs (2.75# density) or damaged insulation boards. It is ideal for filling pitch pockets, low ponding water areas on roof decks and fabricating on-site cant strips. 

FROTH-PAK bonds to most construction materials including lumber, plywood, particleboard, foamboard, masonry, metals, drywall, concrete and foam panels.

FROTH-PAK consists of two main intermediate components — Polyol (A) and Isocyanate (B) — that are mixed together to form polyurethane foam. Both “A” and “B” tanks are pressurized. The hose assembly (which is attached to the gun applicator) includes two hose lines; one is connected to the "A" tank and one is connected to the "B" tank. 

• When the tanks are turned on, the system becomes pressurized.
• An impingement type mixer/spray nozzle is inserted into the face of the gun.
• When the trigger is pulled the two chemicals mix together in the nozzle and then spray out to produce foam that expands 3 to 5 times.
• FROTH-PAK will skin over in 30-40 seconds and be completely cured in under one minute.
