ALDOCOAT 395 is a one-part silicone elastomeric coating specifically designed for use in roofing applications. Once cured this liquid applied silicone coating provides a durable, seamless, flexible, waterproof membrane that resists lateral movement , shear and will allow for normal expansion and contraction. Mil for mil, ALDOCOAT 395 provides greater UV protection than similar coatings and offers increased resistance to moisture penetration. ALDOCOAT 395 provides excellent long term protection through exceptional weatherability properties.
ALDOCOAT 395 was specifically developed as a protective coating for metal roofs, single ply membranes, granulated modified bitumen and sprayed-in-place polyurethane foam roofing. ALDOCOAT 395 is also used as a top coat over ALDOCOAT 384 Polyurethane in membrane restorations. With excellent adhesion to all substrates and exceptional durability, ALDOCOAT 395 is proven to provide excellent solar reflectivity, UV protection and long-term waterproofing performance, including silicone spray waterproofing.
