FIELD: chemistry.
SUBSTANCE: method involves adding a dispersion additive to paint based on chlorinated polyvinyl chloride and glyphtal resin. The paint components are mixed. The coating dries in 10 days. The additive is silicon dioxide nanopowder ultrasonically dispersed in a solvent in ratio of 1:10-1:20 pts.wt. The amount of nanopowder in the paint is equal to 0.005-0.01%.
EFFECT: invention enables to obtain a coating with double the wear resistance without losing elasticity.
