These fasteners are ideal for applications or manufacturing environments where a permanent bond to the substrate is required. They are available both in a molded vinyl hook and knit loop that offers a low profile and low to medium cycle life or in the traditional woven hook 88 and loop 1000 that offers high cycle life.

Heat Activated Pre-Coat (43)
A non-tacky adhesive pre-coat applied to the back of VELCRO® Brand tapes. This product is activated by the use of ultrasonics and dielectrics (RF) machinery or other common heat-generating equipment. This adhesive will bond to a wide range of fabrics and plastics and has excellent water resistance. Ultimate bond strength is achieved in 24 hours. The service temperature of this adhesive is -40°F to 160°F.
1. ULTRASONIC WELDING -Pre-coated tape should be positioned on top of substrate. A perimeter weld at least 1/8" wide should be sued to prevent peel delamination. Machine settings including pressure, weld and dwell (hold time) should be varied according to weld patterns, materials utilized, and bond strength desired. Machine settings including pressure, weld and dwell (hold time) should be varied according to weld patterns, materials utilized and bond strength desired.
2. DIELECTRIC WELDING (RF) - Pre-coated tape should be positioned on top of substrate (commonly vinyl). A perimeter weld at least 1/8" wide should be used to prevent peel delamination. Machine settings including energy level, pre-seal, seal and cool times may vary according to weld patterns and materials being used.
3. IRON - Substrate (commonly fabric) should be positioned on top of pre-coated tape. Pass iron over substrate several items at incremental heat settings until adhesive softens onto substrate. Do not allow adhesive to contact hot iron surface. Allow to cool before hand peel testing.
