About ASI Aquarium Silicone Sealant Black

ASI Aquarium Silicone Black Sealant is a one-part RTV silicone that cures into a durable long-term rubber and is safe for aquatic life. 

Due to its exceptional tensile, elongation, and tear strength, it has been used for decades by leading aquarium manufacturers for usage during production and repair. ASI Black Aquarium Sealant has excellent clarity and offers excellent adhesion to glass without needing to be primed. ASI Aquarium Black Sealant can be used in both saltwater and freshwater tanks to create a waterproof seal. Because it is a thick sealant, it can be applied to vertical and overhead applications without sagging or slumping.
