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. For a long-lasting and efficient high-grade silicone sealant that can be used on a wide variety of surfaces and in various environments, including extremely low and high temperatures, Silicone Depot’s RTV silicone sealant is the right choice for the job. 


It’s an extremely versatile product and can be used for most construction needs. However, it is not recommended for use on vinyl windows, vinyl doors, vinyl siding, vinyl or coated guttering applications, concrete, stone, brick, or most masonry work. If you need silicone sealant for masonry work or for other specialty surfaces, check out our Project 1 Neutral Cure Silicone Sealant.

    Adhesion and service

    The service at silicone depot is the best! Always in stock and super fast shipping. I buy several different RTV products and the quality is excellent. I don’t buy from anywhere else.

    Best in kind

    I was looking for a plain black silicone caulk and encountered with SiliconeDepot by accident. However, I was so satisfied with the product. It worked so well. In fact I am going to order some more in volume.
