ProPink™ Sub-Zero Foam Sealant

Owens Corning™ PROPINK™ Sub-Zero Foam Sealant is a multi-purpose one-component polyurethane foam designed specifically to seal gaps and cracks in both new and retrofit applications. The formulation was specifically designed for extreme temperature and low humidity conditions. The propellant/blowing agents are non-ozone depleting (non-CFC, non-HCFC) and environmentally compliant. Insulating Foam Sealant is designed to fill and seal cracks, crevices, and smaller cavities on flat or irregular surfaces.

Features and Benefits
  • 24 oz. can of a 1-component polyurethane
  • Requires a reusable dispensing gun which allows for metered applications
  • Non-ozone depleting, hydrocarbon propellant
  • Works in cold winter climates or high desert heat
  • Will adhere to most building materials (exceptions: Teflon, silicone, oils and greases, mold release agents, and similar surfaces)
  • Interior/exterior use
  • Tan foam
  • Tack free in 5-10 minutes
  • Cuttable in less than an hour
  • Fully cured within 24 hours depending upon moisture and temperature conditions
  • Seals gaps and cracks around the home to reduce dust, pests, and air infiltration.
  • Can be used over a wide range of extreme temperatures
  • Will cure in temperatures below 0°F (-4°F), and will provide a high flow rate in cold temperature, due to the low viscosity and robust formulation.
  • Can be sanded, painted, stained once cured
  • UL Classified 1-component polyurethane foam
  • Water resistant and will not harm electrical wire insulations, Romex, rubber, PVC, CPVC, polyethylene, or other plastics.
  • May be applied in hot or cold conditions (optimum temperature range between 65°F to 80°F), as long as the working chemical temperature is maintained.
  • When cured, polyurethane foam is permanent, chemically inert, non-reactive and stable for an indefinite period of time.
  • Cured foam is dimensionally stable between -200°F to+240°F
