Our 3M adhesion promoter 111. It's designed to help our 3M VHB tapes adhere to high energy substrates which are historically difficult to form an adhesive bond against. This includes surfaces such as galvanized steel, bare metals and painted surfaces. The isopropyl alcohol based formula dries in one minute to maximize working time and eliminate downtime. Unlike many alcohol based chemicals, it emits a non-offensive odor. In addition to aiding in adhesion, out 3M adhesive primer 111 also works as a surface primer on some surfaces. It cleans and promotes adhesion in a single step, provided the surface is relatively clean and free of wax, grease, oil and loose particles, saving you both time and effort. When tape is bonded in conjunction with our adhesive promoter, it increases the chemical and moisture resistance of the bond while adding additional sheer strength, this ensures the tape won't migrate or unexpectedly detach from the surface.
