Grayling TAC spray adhesive has long been recognized in the environmental remediation industry as one of the best aerosol spray adhesives for seaming together polyethylene film in hot and high humidity environments. The new TAC spray adhesive possesses all of the high performance characteristics that made it so popular with environmental contractors; a wide web spray pattern, fast tack and a strong bond. The new TAC contains no chlorinated solvents or any other ozone depleting chemicals. TAC is CARB and GHS compliant and is now packaged in an award winning, two-piece, polymer coated steel spray can.

TAC is packaged twelve cans per case. Each can contains 20 fluid ounces of product that will provide 600 lineal feet of spray coverage in a 2 wide spray pattern.
