FOSTER Vapor Safe Coating 30-80 18.9Ltr USA

FOSTER® VAPOR-SAFE® COATING is a water-based, fire resistive, flexible, high-solids vapor retarder finish for most types of thermal insulation, including polystyrene foam. It may be used over dry concrete and finishing cement.

VAPOR-SAFE® COATING has a 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, and outdoor use. It is UV 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” (3.2 mm) wet film thickness.

VAPOR-SAFE® COATING meets the requirements of Military Specification MIL-PRF-19565C, Type II using method ASTM E96, Procedure A permeance and is QPD-19565 Listed.

VAPOR-SAFE® COATING contains no asbestos, lead, mercury or mercury compounds.
