Foster® 30-65 VAPOR-FAS™ WB Coating



FOSTER ® VAPOR-FAS WB COATING

Foster ® Vapor-FasTM WB Coating is an economical fire resistive vapor barrier coating for use over many types of thermal insulation including polystyrene foam. It is ideal for use over ASJ, FRK and FSK jackets and board facings to give a vapor barrier seal at joints, laps and weld pin punctures.

Vapor-Fas WB Coating is formulated for indoor and outdoor commercial use. It has a mild latex "paint type" odor and is designed for use on insulated pipes, vessels, ducts and equipment operating between 32°F (0°C) and ambient temperatures.

Vapor-Fas WB Coating has a low WVTR rating effectively sealing against water ingress.

Vapor-Fas WB Coating contains no asbestos, lead mercury, or mercury compounds.

Vapor-Fas WB Coating meets NFPA 90A and 90B 25/50 requirements.

Vapor-Fas WB meets low VOC standards including: · LEED for Schools 2009 IEQ Credit 4.2 · LEED for New Construction, IEQ Credit 4.2 · California Dept of Public Health (CDPH) Standard Method Ver. 1.1, 2010 Small Scale Environmental Chamber Test for VOCs. for CA Specification 01350 · Green Guide for Health Care EQ Credit 4.2 · Collaborative for High Performance Schools (CHPS) EQ Credit 2.2 VOC: 38 g/l, less water and exempt solvents.

LIMITATIONS
Store and apply between 40°F (4°C) and 100°F (38°C), protect from freezing until dry. Always test foil and paper facings, and plastic surfaces for acceptable adhesion before using. Outdoor horizontal surfaces must always drain completely. A pitch of at least 1/2" per foot (4cm/m) is required. To resist rain washoff, allow at least 16 hours drying time above 50°F (10°C), with a relative humidity of 50%. Higher humidity and/or lower temperature may retard drying.
