FIELD: chemistry.
SUBSTANCE: invention relates to a solid resin composition for use in powder coating compositions and for making thermosetting resin for impact-resistance powder coating. The composition contains the following: (a) epoxide resin and (b) amphiphilic block-copolymer containing at least one block segment compatible with epoxide resin, and at least one block segment incompatible with epoxide resin; where the incompatible block segment contains at least one polyether structure, provided that the polyether structure in the said incompatible block segment contains at least one or more alkylene oxide monomer links, having at least four carbon atoms; where the compatible block segment contains at least one polyether structure; where the final resin composition is in solid form. Proposed also is a method of preparing a coating composition curable at normal conditions with high content of solid substance, a method of making a coated base and a coated article.
EFFECT: invention improves impact viscosity of epoxide resins.
