FIELD: organic chemistry, in particular composition for corrosive and chemically stable coats.
SUBSTANCE: invention relates to alkyd-epoxy undercoat compositions based on debris from phthalic anhydride and epoxy resin distillation. Claimed composition contains (mass %) epoxydianic resin 45.0-45.4; modified alkyd resin obtained by stepwise esterification of sun flower oil, polyhydric alcohol and slop from phthalic anhydride distillation with grain-size classification of 0.05-1.1 mm and phthalic anhydride content of 37-80 % - 36.0-36.3; filler 4.9-5.5; pigment 3.5-3.8; balance: solvent; and over 100 mass % of composition it contains polyethylene polyamine as curing agent 15, and cobalt naphthenate as curing catalyst 1.8. Composition of present invention is useful in coating of metal parts and various constructions.
EFFECT: undercoat composition of high corrosion resistance, strength and lower cost.
