Foster® Sealfas® White Insulation Coating and Lagging Adhesive, 1 gal

Foster® Sealfas® coating is a white, fire-resistive, tough, washable, abrasion-resistant indoor coating for thermal insulation. It is also used as a lagging and lap adhesive for canvas and glass lagging cloth. It has excellent brushing characteristics, which will result in better coverage and more uniformly-coated surfaces. It presents a neat white finish and will not yellow or become discolored with age. The surface can be washed-free of grease, oil, soot and other dirt accumulation. Sealfas® coating provides a protective finish for insulation on air conditioning ducts and cold water piping when applied in two coats with reinforcing fabric embedded between coats. When relative humidity exceeds 75% for continuous periods or where the insulated piping or equipment contains chilled-water, brine or refrigerant, additional vapor barrier protection is suggested. Sealfas® coating is compatible with polystyrene and polyurethane foam insulations. It may be applied to the joint or edges of fibrous duct liner insulations to seal and prevent air erosion.
