Foster® VAPOR-FAS™ WB COATING is an economical, fire-resistive, vapor retarder coating for use over many types of thermal insulation including polystyrene foam. It is ideal for use over ASJ, FRK and FSK jackets and board facings to give a vapor retarder seal at joints, laps and weld pin punctures. VAPOR-FAS™ WB COATING is formulated for indoor and outdoor commercial use. It has a mild, latex "paint type" odor and is designed for use on insulated pipes, vessels, ducts and equipment operating between 32 deg F (0 deg C) and ambient temperatures. VAPOR-FAS™ WB COATING has a low WVTR rating effectively sealing against water ingress. VAPOR-FAS™ WB COATING meets NFPA 90A and 90B 25/50 requirements when used to seal seams and punctures in vapor retarder facings and jacketing.
