Tape 8681 HS is made of 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 environment 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 aerodynamics heating(, while providing better peel strength and shock reistant at very low temperatures.

Tape 8681 HS comes pre-coated with a long-ageing solvent resistant, presure sensitive acrylic adhesive, protected with an easy release liner.

Tape 8681 HS 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 whilw 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 Adhesive Promoter 86.

This tape is used in military, commercial, business and private avaition as lead edge protection against particle and rain erosion.

Polyurethane Protective Tapes are a fast and exact way to provide exceptionally tough surface protection onmetals and plastics.

They are made from highly durable thermoplastic elastomer and precoated with either a natural rubber or high performance acrylic adhesive.

They conform well to curvatures, can be precut into convenient shapes and can even be painted or printed over without priming.
