Cool Roof Store Silicone is a single component solventless moisture cure elastomer, designed for use as a cure in place of waterproofing roof coating system which can be sprayed, rolled or brushed onto the desired substrate. This system resists weathering, aging, oxidation and precipitation due to the silicone backbone of the cured polymer. It also, withstands high temperatures and UV radiation, reflecting the heat from the substrate which helps reduce cooling costs during periods of high outside temperatures.
