Aqueous, one-component coating composition and use thereof in processes for repair lacquer coating of plastic substrates

摘要

The invention is directed to an aqueous coating composition composed of chlorinated polyolefins and one or more water-borne, self- emulsifying epoxy resins. The epoxy resin is formed from a combination of aromatic polyols, diepoxy compounds and a condensation product formed from diepoxy compounds and aliphatic polyols. The composition is free of emulsifiers yet forms homogenous mixtures in aqueous media. The composition exhibits strong bonding to plastic substrates.
