Abstract

Corrosion protection and good adhesion of temp. indicator colour pigments for use as safety devices against overheating for example on machinery, containers, chemical and industrial installations, walls, building interiors or exteriors, are achieved simultaneously by mixing a thermo-end point colour pigment (in examples chlorinated phthalocyanine derivs. or CoNH4PO4.H2O) with a binder imparting weather-proofness, pref. cyclised rubber, polysiloxane or chlorinate diphenyl, and preparing a spreadable compsn. by addition of a solvent, pref. benzene. Pref. compn. also contains a filler, such as SiO2 or BaSO4, in pref. amount such that intensity of colour transition is determined by ratio thermo-end point colour pigment to filler.
