Figure 4: At higher ambient temperatures the working time for MMA adhesives is reduced. Epoxy, the highest strength adhesive available, has a high crosslink density, typical tensile strengths in the range of 27-36 MPa, elongation
Tack vs adhesion
Did you know?
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.

It prevents ...
WebTack, or the label adhesive’s initial attraction to a surface with minimal pressure. An adhesive with strong tack will hold firmly to a surface with very little pressure, while an adhesive with weak tack may need consistent pressure over time for a strong seal.
WebTack vs. Cure Basic Knowledge When looking at the bond strength of adhesives, it is important to differentiate the strength of the bond when the substrates are initially bonded from the strength of the bond after the adhesive has cured - Tack vs. Cure.
