  • Patent number: 8298350
    Abstract: A chromium-free conversion coating is prepared by the addition of inorganic salts to dispersions of conducting polymers which are then exposed to alloys of aluminum or other metals. Advantageously, the performance of the coating is comparable to that of known Cr (chromium)-based methods for a number of aluminum alloys having particular significance in the manufacture of aircraft.

  • Patent number: 6506715
    Abstract: An automobile wash and wax composition suitable for simultaneously washing and waxing a soiled exterior surface of a vehicle without buffing. The automotive wash and wax composition being an aqueous emulsion containing an anionic surfactant, a silicone oil, an amino-functional silicone, a wax, and a cationic emulsifier. The wash and wax composition is applied to a pre-wetted exterior surface of a vehicle so as to substantially coat the surface of the vehicle that requires cleaning and polishing. After the coated surface has substantially dried, the surface is washed with a sufficient quantity of water to rinse away the soil particles and the residue of the anionic surfactant, leaving behind a durable, evenly distributed, high-gloss, water resistant protective film of silicones and wax on the vehicle surface, without any buffing of the surface.
