NuFlex 302 Bath & Kitchen Silicone Sealant

NuFlex 302 Bath & Kitchen Silicone Sealant is a 100% medium modulus, one component caulking material with a consistency similar to that of toothpaste. NuFlex 302 cures to form a tough, rubbery solid upon exposure to moisture in the air. Because it does not flow due to its own weight, the ceiling can be applied overhead or on sidewall joints and surfaces without sagging, slumping or running off. It adheres to clean metal, glass, most types of wood, silicone resin, vulcanized silicone rubber, ceramic, natural and synthetic fiber, painted surfaces and many plastics. NuFlex 302 has good resistance to weathering, vibration, moisture, ozone and extreme temperatures. It may be applied in sub-zero weather without loss of extrusion or physical property characteristics and is effective to -46° C (-50° F).
