Marine Grade Silicone Sealant

3M™ marine grade silicone sealant is a one-component cure, silicone sealant engineered to withstand the harsh marine environment. It is a mildew-resistant, non-sagging, moisture-curing silicone rubber sealant for above the waterline applications. The sealant is high-temperature resistant and remains flexible even after years of exposure. It adheres to bare and painted metal, fiberglass, glass, non-oily woods, plastics, and abraded rubbers. 3M marine grade silicone sealant is weather-resistant and formulated to resist mildew and form a non-yellowing seal. The non-shrinking and non-sagging properties of this product offer a simple and efficient application.
