The CR390 is a rubberized and fibered aluminum coating for roofing. Composed of asphalt, mineral fibers, elastomer and aluminum paste, this product serves as a decorative coating and waterproofing for roofs, flashings, buildings and metal structures in one step. It is ideal for filling cracks or covering possibly damaged screw heads. The reflective aspect repels UV rays, lowers heat’s absorption on the surface and delays the contraction and dilation of various substrates. Application on metal prevents the oxidation phenomenon that causes rust. They provide excellent flexibility and weather resistance properties. It is recommended as a topcoat in combination with the Flex Condor product line.
