Foster® 85-23 DUCT-FAS® ADHESIVE
FOSTER DUCT-FAS® ADHESIVE (NON-FLAMMABLE)
FOSTER DUCT-FAS Adhesive is a blue quick-setting, synthetic elastomeric 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. Non-flammable chlorinated solvents eliminate explosion and fire hazards during application.
DUCT-FAS Adhesive has full coverage spray characteristics with little tendency to cobweb when applied with conventional or airless spray equipment. It features extremely fast tack and bond strength development.
DUCT-FAS Adhesive is non-flammable in the wet state and fire resistive when dry. It meets the requirements of ASTM C-916, Type II (ASC-A-7001, Type II).
DUCT-FAS Adhesive meets NFPA 90A and 90B 25/50 requirements.
DUCT-FAS Adhesive is produced under the classification and follow-up service of Underwriter's Laboratories, Inc.
DUCT-FAS Adhesive contains no asbestos, lead, mercury, or mercury compounds.
Store and apply between 40°F (4°C) and 100°F (38°C). Always test plastic materials for compatibility when using a solvent base product. Application equipment must not contain aluminum parts. Not suggested for sealing vapor barrier jackets. Overhead applications may require mechanical fasteners. 08/09
