Foster 30-80 Vapor-Safe Coating AF (Fungus Resistant)

FOSTER® VAPOR-SAFE® COATING AF 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. It is designed for use in high humidity areas to resist mold, fungus and mildew growth on its surface and protect the insulation system from their discoloring and deteriorating effects. Formulated for both indoor and light duty, commercial, outdoor use. It is UV resistant. Ideal for vapor sealing ASJ, FRK and FSK jackets and board facings at joints, laps and over staple and weld pin punctures.

VAPOR-SAFE® 30-80AF™ meets the requirements of Military Specification MIL-PRF-19565C, Type II using method ASTM E96, Procedure A permeance.

VAPOR-SAFE® COATING 30-80AF meets the requirements of: VOC Emissions and Content requirements to contribute to LEED v4 EQ Credit: Low Emitting Materials – Paints and Coatings. VOC Content: 36 g/l, less water and exempt solvents.
