3M 8671HS Polyurethane Protection Tape
3M 8671HS is made of an exceptionally tough abrasion and erosion resistant polyurethane formulated especially for its excellent resistance to ultraviolet light. There is little or no discolouration after prolonged periods of environmental exposure. The high shear strength (HS) capability of this product was formulated to give better erosion resistance and better performance at high temperatures (such as those caused by aerodynamic heating), while providing better peel strength and shock resistance at very low temperatures. 8671HS comes pre-coated with a long-ageing, solvent resistant, pressure sensitive acrylic adhesive and is protected with an easy release liner. 8671HS can be applied by normal "wet" application techniques which allow ready sliding and repositionability, or by dry application techniques where complex curves need to be coated while allowing some repositionability. The product is easy to apply and stretches to conform to difficult contours where this is desired. For especially high adhesion the surface to be coated can be primed with 3M Adhesion Promoter 86. Applications include surface protection applications in aerospace.
