HEAT-INDICATING ANTIRUST COATING Russian patent published in 2016 - IPC C09D5/26 G01K11/12 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement of temperature by means of temperature-indicating paints, used in conditions of hindered access to facility, for example, in nuclear reactors, aircraft and space engines, as well as in making components of semiconductor electronics. Described is irreversible temperature-indicating antirust coating visualising transition in temperature range of 540-590 °C, containing red lead of analytically pure grade with binding substances selected from group of silicone lacquer KO-815, copolymer of styrene with divinyl or polybutyl methacrylate.

EFFECT: technical result is chemical resistance, mechanical strength, anticorrosive properties of coating, having bright colour transition.
