FIELD: chemistry.
SUBSTANCE: invention relates to a polyurea coating composition and a method for application thereof on a substrate. The composition includes a) an amino-functional component which includes: (i) an aspartate-based amino-functional resin; and (ii) a blocked primary amine; and (b) an isocyanate-functional component which includes: (i) a polyisocyanate with functionality greater than 2.0 and isocyanate equivalent weight greater than 300; and (ii) isocyanate silane or methacryloxysilane.
EFFECT: coatings obtained according to the invention have high adhesion to pre-applied coatings or to a substrate or have a relatively low viscosity, which can improve fluidity of the coating composition and enables storage thereof for a longer period of time.
