COMPOSITION FOR ANTI-CORROSION PROTECTION AND METHOD OF OBTAINING IT Russian patent published in 2008 - IPC C09D5/08 C09D109/00 C09D193/00 

FIELD: chemistry.

SUBSTANCE: composition includes binding agent - modified with hexamethylentetramine mixture of tal pitch and technical lignosulfonates in presence of catalyst - zinc oxide, tal modified colophony, pigments - aluminium powder and titanium dioxide, zinc phosphate, neutralising filler - calcium oxide and/or calcium hydroxide and/or chalk and/or microcalcite and/or microtalc, hardener- polyethylenpolyamine and organic solvent. Composition is obtained by first mixing (modification) mixtures of tal pitch, technical lignosulfonates and hexamethylentetramine at temperature 120-140°C in presence of catalyst - zinc oxide. Mixture is cooled, tal modified colophony, pigments are added. Neutralising filler, hardener and solvent are added.

EFFECT: increased light-resistance of coating, extension of colour range and quick drying.
