Excellent resistance to UV light, high temperatures, and moisture make silicone sealants the best choice for long-lasting seals outdoors. They’re better for use on solid surfaces but also create good seals on porous surfaces. These sealants are also known as RTV (room-temperature vulcanizing).

The strongest sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

These sealants withstand exposure to fuels, oil, and solvents.
