Description

Premium 100% RTV Silicone Sealant (Available in Multiple Colors)

Our premium industrial grade 100% RTV silicone sealant is the best choice for most general construction projects. Whether you’re just working on a simple DIY project in your own home or you’re a professional contractor looking for a strong silicone sealant to assemble products, this sealant’s extreme flexibility and durability make it an efficient and affordable choice. The premium industrial grade 100% RTV silicone sealant is fluid and easy to apply but its adhesion packs a major punch, lasting for years longer than most alternatives. 

Our premium industrial grade 100% RTV silicone sealant is widely known in the industry for its ability to withstand both extremely low and extremely high temperatures, making it ideal for creating perfect seals on gaskets and for use in outdoor areas where they might be exposed to the elements, weather events, and more. 

Our silicone sealants can also be used as a superior adhesive for bonding surfaces together, making them the number one choice of manufacturers for assembling their products.

    Premium 100% RTV Silicone / Clear

    I have used silicone to fasten my trim pieces in place for over 30 years. While this stuff has sky rocketed in price in the past two years, Silicone Depot.com has the lowest price. Quality seems to be there and time will tell if it holds as good as others. I have no doubt it will as good or better. Thanks.
