WebFactory applied pre-coated adhesive backings, available on most VELCRO® Brand hook & loop tapes, provide the strongest adhesive bond to the tape itself and can be made ready for instant bonding by many easy methods of application (e.g., solvent, heat, ultrasonic, dielectric, etc.). They can also be used as a tie coat for a liquid adhesive.

WebThe distinction between tack and peel is the contact time as defined by the above definition. Consequently, the test must be designed that the tack probe makes contact with the adhesive for a very short time. In contrast, peel tests require that the adhesive be in contact with the substrate for a long period of time. WebTack and cohesion are tailored to the application. Adhesion is of secondary importance. Many applications require a balance between tack and cohesion. Tack guarantees instant adhesion to the substrate, while cohesion is important for removal without residue.
