Foster® 30-80 VAPOR-SAFE® Coating
FOSTER ® VAPOR-SAFE ® COATING
FOSTER ® VAPOR-SAFE ® COATING is a water base, fire- resistive, flexible, high solids vapor barrier finish for most types of thermal insulation, including polystyrene foam. It may be used over dry concrete and finishing cement.
VAPOR SAFE COATING has the water resistance and low water vapor permeance normally found in only solvent based products. It can be used in high humidity environments, and greatly retards water vapor permeation. It is non-flammable in the wet state.
VAPOR SAFE COATING is formulated for both indoor and light duty commercial outdoor use. It is U.V. resistant. It has a mild latex "paint type" odor, and is designed for use over insulation on pipes, vessels, ducts, and equipment operating at cryogenic up to ambient temperatures.
VAPOR SAFE COATING is ideal for vapor sealing ASJ, FRK, and FSK jackets and board facings at joints, laps and over staple and weld pin punctures. It is an excellent duct board closure sealant. Do not exceed 1/8" (3.2mm) wet film thickness.
VAPOR SAFE COATING meets the requirements of Military Specification MIL-PRF-19565C, Type II and is listed in the QPD-19565.
VAPOR SAFE COATING meets requirements for LEED IEQ 4.2 Low-Emitting Materials, Paints and Coatings. VOC: 33 g/l, less water and exempt solvents.
VAPOR SAFE COATING conforms with current requirements regarding use in meat and poultry processing areas under federal inspection. Letter of certification is available upon request.
VAPOR SAFE COATING contains no asbestos, lead, mercury, or mercury compounds.
Store and apply between 40ºF (4ºC) and 100ºF (38ºC), protect from freezing until dry. To resist rain washoff, allow at least 8-12 hours drying time above 50ºF (10ºC), with a relative humidity of 50%. Higher humidity and/or lower temperature may retard drying. Always select Vapor-Safe Coating in the white color for use over polystyrene on outdoor installations. After long term outdoor exposure 30-80 may weather to an off-white color. Always test foil and paper facings for acceptable adhesion before using. Outdoor horizontal surfaces must always drain completely. A pitch of at least 1/2" per foot (4 cm /m) is required. For heavy duty/industrial outdoor applications select Vapor-Safe Mastic 30-90.
