SELF-CLEANING PAINT COATING AND A METHOD AND AGENT FOR PRODUCING THE SAME

摘要

A self-cleaning paint coating that exhibits the LOTUS EFFECT and an agent and a method for producing the same. The paint coating comprises a paint base coat and a topcoat. The topcoat includes structure-forming particles and is at least partially hydrophobic. The structure-forming particles have an average particle diameter of less than 100 nanometers (nm) and form elevations in the topcoat surface that are interspaced at a distance of less than 50 nm. The topcoat of the paint coating is formed from the agent. The agent contains a liquid medium, a hydrophobating agent dissolved in the liquid medium, and structure-forming particles suspended in the medium. The method of forming the paint coating comprises coating a substrate with the base coat, applying the topcoat agent to the partially cured or uncured base coat, and curing of the top coat, and if required, the base coat.
