COATING COMPOSITION CONTAINING POLYUREA AND APPLICATION METHOD THEREOF Russian patent published in 2012 - IPC C08G18/10 C08G18/32 C08G18/38 C09D175/02 

FIELD: chemistry.

SUBSTANCE: coating composition contains polyurea obtained from a reaction mixture containing: a) a first component containing isocyanate; and b) a second component containing (meth)acrylated amine obtained through a reaction between a polyamine and mono(meth)acrylate, and at least one additional amine selected from: (a) a product of a reaction between (meth)acrylate, dialkylmaleate and/or dialkyl fumarate and an amine; (b) a diamine with the structure , where R3-R6 independently denote C1-C10 alkyl; (c) a diamine with the structure , where R7-R10 independently denote C1-C10 alkyl; (d) polyoxyalkylene diamine and/or polyoxyalkylene triamine, having primary amino groups or secondary amino groups which are not formed as a result of reaction between polyoxyalkylene diamine and/or polyoxyalkylene triamine and (meth)acrylate; (e) a diamine containing an aspartic ester functionality and does not contain any other functionality which might be reactive towards isocyanate; (f) a product of a reaction between triamine and diethylmaleate and/or dibutylmaleate; and/or (g) a product of a reaction between a polyamine and mono- or polyepoxide; where the ratio of isocyanate group equivalents to amine group equivalents is greater than 1, and isocyanate and (meth)acrylated amine, which is a reaction product, can be deposited onto a substrate in volume ratio of mixture components equal to 1:1. The invention also describes a method of coating a substrate, involving deposition onto at least part of the substrate of said coating composition, and a substrate at least partially coated by a coating made from said composition.

EFFECT: preparing coating from disclosed coating composition, which does not give aftertack from the substrate, has good hardness and endows the substrate with corrosion resistance, wear resistance, impact resistance, fire- or heat resistance, chemical resistance, structural integrity and decoration.
