METHOD OF PRODUCING URETHANE CURING AGENTS FOR ELECTRO-DEPOSITED PAINT, CATIONIC ELECTRO-DEPOSITED POLYMER COMPOSITION CONTAINING IT FOR ELECTRO-DEPOSITED PAINT AND ELECTRO-DEPOSITED PAINT COMPOSITION Russian patent published in 2017 - IPC C09D175/04 C09D7/12 C09D5/44 

Abstract RU 2637029 C2

FIELD: chemistry.

SUBSTANCE: method comprising the step of reacting a blocking agent, which is selected as an aromatic dihydric alcohol or a mixture of an aromatic dihydric alcohol and an aliphatic dihydric alcohol and a polyisocyanate; to a cationic polymer composition containing a curing agent for the electro-deposited paint, and to an electro-deposited paint composition.

EFFECT: electro-deposited paint composition containing the curing agent according to the present invention can reduce the weight loss during sintering and have an excellent surface roughness and an internal painting ability.
