LaGrange, Ohio — West Development Group’s (WDG) two new solvent-free silicone roof coatings, HSS 535 and HSS 540 R2R, are both 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, these WDG silicone roof coatings should be applied to a dry, frost-free surface. According to the company, 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. www.wdgsilicones.com.
