Abstract

The composition was developed for a new high-efficiency silicon-containing protective conversion coating for application to zinc-plated surfaces. It was proven experimentally and theoretically that this new environmentally safe coating is comparable in corrosion resistance and protective power to environmentally hazardous chromate coatings; however, unlike the latter, the former is efficient at high temperatures (to 150°C). For extra protection of a material being coated, it was proposed to additionally apply a new, nontoxic (hazard class 4) organic film based on gallic acid esters.
