Description
NuFlex® 302 General Purpose Silicone Sealant is a medium modulus one-component acetoxy cure, non-sag caulking material. NuFlex® 302 General Purpose Silicone Sealant cures to form a sturdy, rubbery solid upon exposure to moisture in the air. Due to its non-sag properties, the sealant can be applied overhead or on sidewall joints and surfaces without sagging, slumping, or running off. It adheres to most non-porous construction substrates.
NuFlex® 302 has excellent resistance to weathering, vibration, moisture, ozone, and extreme temperatures. It may be applied in sub-zero temperatures without loss of extrusion or physical property characteristics and is effective to -46°C (-50°F)
