FOSTER 40-30 is a low odor, quick setting water-based surfacing material designed for field or shop application to faced or unfaced fiberglass duct liner, fiberglass duct board insulation or galvanized surfaces. It is formulated to effectively prevent the spread of molds and odor-causing bacteria on its surface with long term activity. Its low viscosity allows for application with virtually any type of spray equipment now available to the market. FOSTER 40-30 guards against the regrowth and spread of odor causing bacteria and molds on the surface of the coated HVAC system or its treated components only. As a result, the building occupants may enjoy a work space free of the odor problems often associated with contaminated HVAC duct systems. FOSTER 40-30 dries to form an effective air erosion preventive surfacing material sealing and reinforcing the surface of new or aged duct liner insulation materials. FOSTER 40-30 is non-flammable when wet and extremely fire-resistive when dry. When tested on both faced and unfaced fiberglass duct liner insulation, Foster 40-30 produced flame and smoke ratings below the 25/50 NFPA 90A and 90B requirements. The dry film stays flexible and moisture resistant. It will not cause flash rusting on metal surfaces. FOSTER 40-30 contains no asbestos, lead, mercury, or mercury compounds.
