FIELD: beverage industry. ^ SUBSTANCE: invention relates to production of water-dilutable composition used, in particular, for protecting inside surfaces of aluminum cans for beer, soda and soda-free low-alcohol and soft drinks. Composition contains, wt %: epoxide oligomer with molecular mass 2000-10000 - 5,7-9,0, unsaturated monomers 10.0-22.0, benzoyl peroxide 1.2-3.2, organic solvents 9.0-14.5, neutralization agents 1.4-5.0, distilled water 46.5-69.9, epoxide oligomer with molecular mass 200-500, and, as curing agent, water-dilutable melamine-formaldehyde oligomer 0.5-1.2, said unsaturated monomers being selected from methacrylic acid, methyl methacrylate, styrene, and ethyl acrylate. ^ EFFECT: increased continuity of coating and resistance to hydrolysis on storage, which assures preservation of sedimentation stability and invariability of dispersion composition over at least two years. ^ 1 tbl, 5 ex |
