  • Patent number: 7544411
    Abstract: 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.

    Abstract: A substrate of glass, ceramic, plastic and metal, or a glazed or enamelled substrate, with a self-cleaning and/or hydrophobic surface. The substrate having disposed thereon a coating that includes a plurality of particles affixed to the surface of the substrate by a binder. The particles are preferably of nanoscale size and extend outwardly from a surface of the coating to form a nano-rough surface. The nano-rough surface causes a hydrophobic or water repellent effect. The binder can be formed from an organic or an inorganic material and operates to fix the plurality of particles to substrate surface.
