Silicone Roof Coating: West Development Group

HSS 535 and HSS 540 from West Development Group are one-component, moisture-curing silicone rubber roof coatings designed for use on sprayed-in-place polyurethane foam.

These coatings can be rolled or spray-applied and touch-up work can be done with a brush or a roller. Ready to use on commercial or industrial roofs, silicone roof coatings should be applied to a dry, frost-free surface. They are tack-free within one to two hours and cure at normal temperatures in two to six hours by reacting with moisture in the air, forming a durable and flexible moisture-free seal.

When applied properly, both coatings form a seamless, self-flashing seal; resist oxidation, wind-driven rain and snow, as well as ozone; and offer resistance to cracking, peeling, shrinking, or becoming brittle and stiff.
