FOSTER SPARK-FAS ® WB ADHESIVE

FOSTER SPARK-FAS WB Adhesive is a high tack, rapid-setting water base adhesive used to adhere fibrous glass or mineral wool insulations (up to 6 lbs. density) to painted or unpainted steel, galvanized or aluminum air conditioning or hot air ducts. A synthetic elastomer emulsion, it is non-flammable when wet and extremely fire-resistant when dry. Its consistency resists dripping and spattering.

SPARK-FAS WB Adhesive is ideal for bonding fibrous glass and rigid plastic foam insulations to wood, concrete or other materials of construction.

SPARK-FAS WB Adhesive meets ASTM C 916, Type 1 (ASC-A-7001, Type 1) requirements.

SPARK-FAS WB Adhesive meets MIL-A-3316C, Class 2, grade A requirements, and is listed on the QPL.

SPARK-FAS WB Adhesive meets NFPA 90A and 90B 25/50 requirements.

SPARK-FAS WB Adhesive meets requirements for LEED IEQ 4.1 Low-Emitting Materials, Adhesives and Sealants. VOC: 66 g/l, less water and exempt solvents.

SPARK-FAS WB Adhesive contains no asbestos, lead, mercury, or mercury compounds.

LIMITATIONS
Store and apply between 40ºF (4ºC) and 100ºF (38ºC), protect from freezing until dry. Always test plastic foam insulation for warpage when using a water-base adhesive. Overhead applications may require mechanical fasteners. Not suggested for use between two impermeable surfaces.
