Foster 85-20 Spark-Fas Adhesive

Foster® 85-20™ 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 90 B 25/50 requirements.
