SCM3400 silicone roof coating is a liquid applied one part silicone coating that is an excellent candidate to consider for use in roofing applications as the weathering coat over a variety of roofing materials including spray applied polyurethane foam, water-borne coatings (acrylic), PVC membranes, and galvanized/coated metals. SCM3400 silicone roof coating forms a durable, breathable, watertight and weatherproof barrier that is extremely resistant to degradation from natural weathering.

Typical Performance Properties: 

• Silicone Durability – Once cured, silicone rubber exhibits excellent long-term resistance to natural weathering including: extreme temperatures, ultraviolet radiation, rain and snow, with negligible change in elasticity. 
• Versatile Application – SCM3400 is a one-part liquid applied silicone material that requires no mixing and can be applied by spray, roller or brush.
• Ease of Use – Low spraying viscosity permits easy spraying with most commercially available spray equipment while high static viscosity facilitates the material remaining where it is applied in areas of high pitch, vertical walls or parapets until full cure is achieved.
• Ample Work Life – Long work life provides sufficient time for treatments such as application of granules.
• Accelerated Cure Rate – Quickly attains its weather resistant properties.
• Low Temperature Storage – Storage may occur in unheated warehouses during the cooler months without the risk of freezing.
