Cool-Sil is a silicone rubber, fluid-applied roof system that is solvent-free, high solids, one-component, and moisture-curing. This system restores aged smooth surface BUR, granulated cap sheets, single-ply membranes, and metal roofs. It can also be used as a repair material for maintenance applications. Cool-Sil provides excellent UV resistance, adhesion, and breathability and has exceptional waterproofing properties. It is easily applied by roller, squeegee, or brush. Ready to use - This one-part material can be applied easily to a dry, moisture-free, and clean surface and is quickly rain-safe. It fully cures in 1 to 4 hours based on temperature and humidity by reacting with moisture in the air. Protective - Cool-Sil provides long-term protection because it resists weathering, aging, oxidation, rain and snow, the effects of ozone, ultraviolet radiation, and temperature extremes typically found on roofs. Durable - With its high solids content and absence of hydrocarbon solvents, Cool-Sil provides a thick, durable, mold- and mildew-resistant roof covering that performs in a wide temperature range in the most severe climatic conditions.
