Abstract
An adhesive composition constituted of a mixture of a one-part heat-curable adhesive and a substantially water-insoluble indicator material which is substantially unreactive with the components of the one-part heat-curable adhesive (i.e. curable resin, heat-activatable curing agent for the resin and accelerator) but which has the ability to produce a color change in the composition on curing of the adhesive. Preferably, the adhesive is a one-part heat-curable epoxy adhesive system. The use of the adhesive composition enables a visible detemination of the point of cure of the adhesive.
