The hook and loop are preshrunk to insure maximum dimensional stability and flatness. These hook and loop fasteners are coated on the backside with an aggressive and tacky rubber based pressure sensitive adhesive designed to function over a range of temperatures and humidity.

The woven hook is covered with tiny, stiff hooks, about 300 hooks per square inch (46/sq. cm.). The woven loop is covered with thousands of soft, pliable napped loops, providing for thousands of openings and closings (cycles).
