COMPOSITION FOR COATING METAL BASE Russian patent published in 2012 - IPC C09D5/10 C09D1/02 C09D7/12 

FIELD: chemistry.

SUBSTANCE: the invention relates to compositions for coating suitable for coating a metal base (preferably a steel one), which will be installed and coated with external cover. The composition contains zinc powder and/or zinc alloy powder and colloid solution of modified silicone dioxide. The colloid solution of modified silicone dioxide contains colloid silicone dioxide particles, modified 6-40% mass of one or several silaned compositions and colloid particles of silicone dioxide. The composition is produced by adding the silaned composition or compositions to colloid solution of the silicone dioxide at the rate below 20 silane molecules per 1 nm² of the silicon dioxide colloid particle surface per hour.

EFFECT: production of coating composition with considerable durability, good resistance to white rust and good film properties.
