Multisil SCS5500 sealant is a one-part, neutral-cure silicone sealant engineered for exceptional weatherproofing performance in new construction or restoration projects.

Multisil SCS5500 sealant is a low-modulus silicone sealant that combines flexibility, durability, and ease of use. Designed for dynamic joints in both vertical and horizontal applications, it cures to a strong, elastic rubber that withstands temperature extremes and UV exposure.

This sealant bonds well to many substrates, including glass, aluminum, polycarbonate, EIFS, masonry, and coated or painted surfaces. It’s also compatible with other Momentive silicone products, making it a versatile solution in complex glazing systems.
