Open the CIPO recordAbstract From the Canadian patent
The specification discloses noncracking permanent 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 plasticized 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.
