FIELD: chemistry. ^ SUBSTANCE: invention relates to protection of metals from corrosion using lacquer coating. This engineering problem can be solved by using calcium hydroxyethylidenediphosphonate with formula CH3(OH)C(PO3)2Ca2 as an anti-corrosion pigment, with higher anti-corrosion activity as compared to the prototype - protonated zinc hydroxyethylidenediphosphonate and a control specimen - zinc tetraoxychromate. ^ EFFECT: low-toxic high performance anti-corrosion pigment. ^ 1 tbl, 3 ex |
