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 sealant can be applied overhead or on sidewall joints and surfaces without sagging, slumping or running off.

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).
