Loop Tack Fixture

The loop tack test measures the tack (instant grip) of an adhesive. The capability to rapidly and reliably bond two surfaces is a key performance requirement in many pressure sensitive adhesive products, particularly adhesive tapes and labels.
A key property for successful bonding is the tack or “stickiness” of the adhesive.Tacky materials can be discerned by touch but for material specification or product development purposes a more quantitative approach is necessary. Tack is defined as the ability of an adhesive to form a bond to a surface after brief contact under light pressure.
