CYCLOALIPHATIC RESIN, METHOD FOR OBTAINING THE SAME AND ITS APPLICATION IN A HIGH RESISTANCE COATING Russian patent published in 2018 - IPC C09D163/00 C09D183/04 C08G59/24 C08G59/40 C08G59/50 C08L63/00 C08L83/04 C09D5/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a cycloaliphatic resin containing silanes with epoxy and alcoxy-silanol functionalities, obtained from the reaction of: a) an epoxy functional silane with the formula , where each R₁ is independently selected from methyl, methoxy, ethoxy or propoxy; "X" can be epoxy-cyclohexyl or glycidoxy group; and "n" is an integer between 1 and 6; and b) a hydrogenated bisphenol with formula , where R₂ is methyl, ethyl or a hydrogen atom. From the cycloaliphatic resin, it is possible to formulate anticorrosive coatings, using the cycloaliphatic resin alone or as hybrid with epoxy cycloaliphatic resins or hydroxy-functionalized resins; both mixed with amino or aminosilane hardeners.

EFFECT: obtained coatings have superior physical properties of weatherability, gloss retention, toughness and impact resistance.
