About Berkebile Super Black Silicone B4

BERKEBILE 2+2® RTV SILICONE INSTANT GASKET MAKER... are a paste-like, one-component material which cures to a tough, rubbery solid upon exposure to moisture in the air. Because it does not flow due to its own weight, this sealant can be applied on overhead or on sidewall joints and surfaces without sagging, slumping, or running off. It is designed as a replacement for gaskets, seals, and gasket dressings. Material typically skins in 15-20 minutes. Typical peel strength is 20 pounds per inch after 72 hours cure-time at room temperature. See product package for instructions.
