FIELD: organic chemistry, pant and varnish industry. SUBSTANCE: invention relates, in particular, to manufacturing composites for anti-corrosive covers for protection articles made of aluminum alloys and steel. The composite comprises epoxy diane resin, urethane modifying agent, anti-corrosive pigment, filling agent, organic solvent and amine hardening agent. As the urethane modifying agent the composite comprises epoxy urethane oligomer of the formula: with an average molecular mass 1900 Da and the content of active epoxy groups 6-7%. As an amine hardening agent the composite comprises organosilicon diamine of the formula: with molecular mass 566 Da and the content of active amino-group 5.7%. The definite ratio of components in the composite provides preparing covers eliciting high adhesion, chemical stability and water resistance that gives a possibility for its using for protection of metallic structures, among them, made of aluminum and its alloys in chemical industry and other branches of economy. EFFECT: valuable properties of composite. 3 tbl, 1 ex |
