Foster® 85-20 Spark-Fas® Adhesive



FOSTER ® SPARK-FAS ® ADHESIVE

Foster ® Spark-Fas ® Adhesive is a quick-setting, non- flammable, fire-resistive, synthetic elastomer adhesive used to adhere duct wrap, fibrous glass or mineral wool insulations (up to 6 lbs. density) to galvanized steel and aluminum air conditioning or hot air ducts, where a fire-resistive dry film is required. Non-flammable chlorinated solvents eliminate explosion and fire hazards during application.

Spark-Fas Adhesive will adhere insulation to wood and concrete. In this application the coverage may not be as great as shown at left.

Spark-Fas Adhesive gives superior service when it is used as a contact adhesive to cement the laps of aluminum foil, FSK, ASJ, and FRK facings.

Spark-Fas Adhesive meets ASTM C 916, Type I (ASC-A-7001, Type I) requirements.

Spark-Fas Adhesive meets MIL-A-3316C, Class 2 grade A test requirements.

Spark-Fas Adhesive meets NFPA 90A and 90B 25/50 requirements.

Spark-Fas Adhesive is produced under the classification and follow- up service of Underwriter's Laboratories, Inc.

Spark-Fas Adhesive contains no asbestos, lead, mercury, or mercury compounds.
