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.

Abstract: An object of cross-linked polymer, such as insulation for a cable conductor or a cable sheath, is formed by using a starting material containing a peroxide and a polymer material with the ability to undergo a cross-linking reaction in the presence of peroxide. The reaction is carried out during at least a part of the process in the presence of a substance which has the ability to undergo a color change during the cross-linking reaction of the polymer material so that a color change of the substance is obtained. There may also be added a dye which does not have the ability to undergo a color change during the cross-linking of the polymer material. The substance may be an aromatic compound containing at least one halogen atom and/or at least one heterocyclic ring in which ring there is at least one nitrogen atom to which no hydrogen atom is linked.
