Foster® 40-30™ Fungicidal Protective Coating
Foster ® 40-30 ™ Fungicidal Protective Coating (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 40-30guards 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 40-30dries to form an effective air erosion preventive surfacing material sealing and reinforcing the surface of new or aged duct liner insulation materials.
Foster 40-30is non-flammable when wet and extremely fire-resistive when dry. When tested on both faced and unfaced fiberglass duct liner insulation, Foster Fungicidal Protective Coating 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 meets requirements for LEED ® EQ Credit 4.2, low- emitting materials: paints and coatings. VOC: 39 g/l, less water and exempt solvents.
Foster 40-30contains no asbestos, lead, mercury, or mercury compounds.
Store between 40ºF (4ºC) and 100ºF (38ºC). Protect from freezing. Apply between 50ºF (10ºC) and 100ºF (38ºC) with less than 70% RH air conditions maintained until dry. Water-based products may corrode carbon steel spray equipment. Corrosion resistant pumps and fittings are suggested. For interior use only. Avoid direct application onto pressurized PVC or CPVC piping and wipe off or remove overspray.
DO NOT DILUTE.
