METHOD OF USING TITANIUM CATALYST FOR PRODUCING MATERIALS CONTAINING CARBAMATE FUNCTIONAL GROUPS Russian patent published in 2019 - IPC C07C269/06 C08G71/04 C08F8/30 C09D175/04 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a method of producing a material, to a material obtained using such a method, which can be used to produce thermosetting coatings, to a coating composition, as well as to a method of applying a coating composition. Method of producing the material involves reaction of a carbamate compound with a material containing hydroxyl functional groups using titanium (IV) alkoxide as a catalyst. Alkoxide of titanium (IV) is used in amount of 0.13 to 1.58 wt%, based on total weight of material with hydroxyl functional groups and carbamate compounds. Carbamate compound used is alkyl carbamate. Material containing hydroxyl functional groups used is polyol having 12 to 72 carbon atoms and at least two hydroxyl groups. Coating composition includes said material containing carbamate functional groups and one or more conventional coating additives. Coating composition application method involves application of said coating composition by any known method onto surface.

EFFECT: invention enables to obtain a colorless material which does not contain tin, and also obtain a coating which has high resistance to scratching, good resistance to acids, good resistance to atmospheric conditions.
