FIELD: chemistry.
SUBSTANCE: invention relates to the development of an epoxy composition for the operative correction of defects in process equipment used in the manufacture of items by injection molding at a thermoplastic automatic machine, contacting with a material having a temperature of 150–175 °C, and can be used in various areas in the products manufacture. Epoxy composition contains an ED-20 epoxy resin in an amount of 100 parts by weight, a hardener methylendic anhydride in an amount of 80 parts by weight, a 1-methylimidazole catalyst in an amount of 1 part by weight.
EFFECT: said epoxy has an operating temperature of 185 °C, as well as the necessary adhesion and mechanical properties.
