Foster® 40-11 Eclipse™ Coating
EclipseTM Coating (40-11) is a low odor, quick setting water- based surfacing material designed for field or shop application to faced or unfaced fiberglass duct liner or fiberglass duct board insulation. Its low viscosity allows for application with virtually any type of spray equipment now available to the market.
Eclipse dries to form an effective air erosion preventive surfacing material sealing and reinforcing the surface of new or aged duct liner insulation materials.
Eclipse is non-flammable when wet and extremely fire-resistive when dry. When tested on both faced and unfaced fiberglass duct liner insulation, Eclipse by Foster 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. Dry Eclipse resists mold, fungus, discoloration from mildew, and stains by mold. Its extremely high level of resistance enhances the longevity of the material.
Eclipse coating meets requirements for LEED ® EQ Credit 4.2, low-emitting materials: paints and coatings.
Eclipse contains no asbestos, lead, mercury, or mercury compounds. It meets NFPA 90A and 90B 25/50 requirements.
Store between 40ºF (4ºC) and 100ºF (38ºC). Protect from freezing until dry.
DO NOT DILUTE.
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.
DO NOT DILUTE.
