ANTI-CORROSION PIGMENT Russian patent published in 2008 - IPC C09D5/08 C07F9/40

Abstract RU 2330054 C1

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.
