FIELD: polymer coatings. SUBSTANCE: invention relates to protective epoxy thixotropic compositions without solvents intended to be applied onto various- destination pipes. High and low molecular weight epoxy resins are mixed in presence of specified amount of acrylic copolymer at 80-100 C for 2-6 h, cooled to 20 C, whereupon plasticizer, thixotropic agent, and pigment are added with stirring and resulting mixture is dispersed. EFFECT: improved smoothness and increased immunity from exposure to alternate temperatures and from corrosive media. 1 tbl, 3 ex
