Bostik 922 INDUSTRIAL SILICONE SEALANT ACETIC CURE 300GM TUBE

Bostik RTV 922 is a one component, acetic cure, high strength, high modulus industrial grade silicone sealant. It cures by absorption of atmospheric moisture to form a flexible and durable elastomeric sealant. Bostik RTV 922 cures rapidly to an even, consistent silicone rubber. Because of its superior adhesion to most substrates, it is extremely effective as a high temperature industrial silicone. It maintains its properties while in contact with a broad range of chemicals and over a broad temperature range.
