POWDER COATING WITH LOW TEMPERATURE OF APPLICATION Russian patent published in 2016 - IPC C09D163/00 C09D5/03 C08G59/40 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of powder coatings, which can be cured at lower temperatures, as well as to a method of application of such coatings on articles. Described are compositions of powder coatings containing a composition of epoxy resin and a curing agent of general formula NH₂-NH-C=(O)-[R¹-C=(O)]_n-NH-NH₂ (1). Compositions of powder coatings can be applied at low temperatures of application of approximately 165-185 °C.

EFFECT: coating compositions can be used for formation of surfaced single-layer and double-layer epoxy coatings for pipes and show optimal resistance to corrosion and flexibility at reduced cathode peeling.
