SUBSTRATES COATED WITH POLYUREA COATINGS AND COMPOSITION Russian patent published in 2012 - IPC C09D175/02 C08G18/10 C08G18/38 C08G18/32 B05D7/00 B05D7/14 

FIELD: chemistry.

SUBSTANCE: invention relates to a metal substrate coated, at least partially, with a coating in form of a multilayer composite comprising at least one layer selected from an electrodeposited coating layer, a base coating layer and a transparent coating layer; and a coating containing polyurea obtained from a reaction mixture containing isocyanate and a product of reaction between a monoamine and poly(meth)acrylate, which is (meth)acrylated amine, in which the ratio of isocyanate group equivalents to amine group equivalents is greater than 1.3:1, and isocyanate and the reaction product, which is (meth)acrylated amine, can be deposited on the substrate in volume ratio of concentration of components of 1:1. The invention also describes a building having a structural element coated, at least partially, with a coating from said polyurea, as well as a substrate coated, at least partially, with a coating from said polyurea, where the ratio of isocyanate equivalents to amine group equivalents is greater than 1.3:1.

EFFECT: coating can attenuate an explosion, eg, protection in case of an explosion or breakage in the immediate vicinity of flying debri formed by an explosion wave.
