ACRYLIC ADHESIVE FOR BONDING VINYL COATINGS ABSTRACT OF THE DISCLOSURE The specification discloses noncracking perma- nent adhesives which utilize mixtures of phenolic resins and methacrylate resins having a Mw greater than about l00,000 and preferably about 400,000 for bonding plasti- cized vinyl resin coverings, e.g., PVC, to hard polymeric substrate surfaces such as ABS, etc. Also, it is preferable that the vinyl resin covering contain plasticizers which are no more than limited in compatibility with the adhesive. It is theorized that the adhesive mixture prevents migration of plasticizer from the plasticizer-containing vinyl resin covering into the adhesive and eventually into the polymeric substrate.
