Aluminum RTV Silicone Gasket Maker 1283

Product Description

ALUMI-SEAL RTV silicone gasket-maker is a single component, RTV (room temperature vulcanizing) silicone rubber. When applied as a formed-in-place gasket, it reacts with moisture in the air and cures to a rubber like product. It will adhere to clean metal, glass, most types of wood, plastic, rubber, and ceramic surfaces. Because it does not flow due to its own weight, this sealant can be applied overhead or on sidewall joints without sagging or running off. This product is corrosive to most metals and is not recommended for electrical connections. Should not be used on head gaskets.
