Abstract
Abstract DISCLOSED IS A THERMOSETTING ADHESIVE WHICH IS FORMED OF A NITRILE PHENOLIC AND APPLIED IN SLURRY FORM ONTO A SUPPORT LAYER OF POLYURETHANE AND THEN DRIED. WHEN HEAT IS APPLIED THERETO THE DRIED NITRILE PHENOLIC WILL SOFTEN TO CAUSE ADHESION OF THE MATERIAL TO A SURFACE TO WHICH IT IS APPLIED. THE NITRILE PHENOLIC IS FORMED OF A MIXTURE OF CARBOXY-MODIFIED NBR POLYMER, THERMOSETTING PHENOLIC RESIN, COUMARONE-INDENE RESIN, AND STERICALLY HINDERED PHENOL OF THE TYPE OCTADECYL 3-(3'',5''-DI-TERT-BUTYL-4''-HYDROXYPHENYL) PROPIONATE. THE NITRILE PHENOLIC AND POLY- URETHANE SUPPORT THEN FORM A THERMOSETTING TAPE WHICH CAN BE SECURED TO A CLIP OR OTHER FASTENER. THE CLIPS OR FASTENERS UTILIZING THE THERMOSETTING ADHESIVE CAN BE FIRMLY SECURED TO THE EXTERIOR PAINTED SURFACE OF AUTOMOBILES BY THE APPLICTION OF HEAT FOR A SHORT PERIOD OF TIME. ALSO THE THERMOSETTING ADHESIVE TAPE CAN BE APPLIED TO THREADED FASTENERS FOR SECURING THE SAME TO WALL SURFACES SUCH AS METAL OR FIBERGLASS FOR SECURING OTHER ARTICLES THERETO.
