Measurement Good Practice Guide No. 26 Adhesive Tack * + ** Bruce Duncan , Steve Abbott and Richard Roberts * Centre for Materials Measurement and Technology, National Physical Laboratory, Teddington. + SATRA, Kettering. ** Pira International, Leatherhead. Abstract: Adhesive tack is the property that controls the instant formation of a bond when an adhesive and a surface are brought into contact. Although tack test methods are generally simple to perform, obtaining reliable measurements can be a problem. This guide is intended to give guidance on the measurement of the tack of permanently tacky pressure sensitive adhesives (including tapes) and adhesives whose tack requires activation in some way. Standard test methods for pressure sensitive adhesives (rolling ball, loop tack, probe tack and quick stick) are discussed. A study of a tack measurement method for the footwear industry is presented as a case study that illustrates the issues involved in measuring the tack of activated adhesives.
