22-65 Mono-Tack Spray Adhesive is a water based spray adhesive designed for fiberglass to metal applications. 22-65 Mono-Tack Spray Adhesive is ideally suited for sheet metal shops and production line operations because it is non-toxic, non-flammable, fire resistant and easy to use yet offers fast tack and high coverage rates for economy. It is a soft creamy paste when applied but dries to a clear film.
