ADOPTED_FROM:CR 14376:2002 The setting of an adhesive is a complex process, during which the adhesive develops its cohesive strength. It takes place in several phases, which are affected by numerous factors e.g. environmental conditions, substrates, coating weight, etc. Terms commonly used, related to the setting process are e.g. open time (correctly termed maximum open time), wet tack, hot tack, green tack, closed time, setting time. This European standard defines these terms in detail and describes the various aspects of the setting procedures used to assess the setting process.
