| Pressure Sensitive Adhesives
Pressure sensitive pre-coats are popular because of the ease of application. Simply remove the release film and press VELCRO® brand tape into place. However, pressure sensitive pre-coats can creep under constant stress or deadload. A general rule of thumb is the greater the tack, the faster the creep; lower the tack, the better the load-bearing characteristics. Pressure sensitive pre-coats should always be considered semi-permanent bonds.
VELCRO® brand molded hook tapes and some of our SOFT HARDWARE® extruded/molded fasteners are also available with a pressure sensitive foam backing, one side of which has been applied to the back of the VELCRO® brand molded tape, the other side of which serves as a pressure sensitive backing.
