Foster® 85-22 DUCT-FAS® Adhesive
FOSTER DUCT-FAS ® ADHESIVE (FLAMMABLE)
FOSTER DUCT-FAS ADHESIVE is a red quick-setting, synthetic elastomer insulation adhesive. It has been designed for use in attaching low density (up to 3#) duct liner, duct wrap, and fibrous glass insulation to sheet metal. It uses a flammable solvent system.
DUCT-FAS ADHESIVE has full coverage spray characteristics with conventional or airless spray equipment with little tendency to cobweb. Its high solids and gel-like consistency make it ideal for vertical or overhead surfaces and for brush or roller application.
DUCT-FAS ADHESIVE meets ASTM C 916, Type IV (ASC-A-7001A, Type IV) and NFPA 90A and 90B 25/50 requirements.
DUCT-FAS ADHESIVE is produced under the classification and follow-up service of Underwriters Laboratories, Inc.
DUCT-FAS ADHESIVE contains no asbestos, lead, mercury, or mercury compounds.
Store and apply between 40ºF (4ºC) and 100ºF (38ºC). Always test plastic and painted materials for compatibility when using a solvent base product. Allow to dry to a solvent-free condition before installing weld pins. Not suggested for sealing vapor barrier jackets. Overhead applications may require mechanical fasteners.
