ELECTRICALLY CONDUCTING PAINT-AND-VARNISH MATERIAL FOR CORROSION PROTECTION OF METALWORK Russian patent published in 2008 - IPC C09D5/08 C09D5/10 C09D123/06 C09D5/24 

FIELD: cathodic protection of metalwork.

SUBSTANCE: proposed paint-and-varnish material for corrosion protection of metalwork includes electrically conducting film-forming agent (electrically conducting polyethylene) and carbon nanotubes, from 10 to 80% of volume of paint-and-varnish material which increase electric conductivity and resistance to aggressive media and consequently mechanical strength of metalwork. Proposed paint-and-varnish material may additionally contain high-dispersed zinc powder ensuring additional cathodic protection from 40 to 90% of volume of paint-and-varnish material.

EFFECT: enhanced efficiency of corrosion protection of metalwork during protracted period of operation due to smooth electrical potential equal to potential of metalwork being protected.
