  • Powder coating composition
    Patent number: 5898043
    Abstract: The present invention provides a powder coating composition comprising a resin powder comprising a film-forming resin and a crosslinking agent capable of giving rise to a crosslinking reaction with the resin, wherein the resin powder has a volume-average particle diameter of 3-17 .mu.m and a shape factor (SF) of 100.5-160. This powder coating composition can form a coating film having luster and smoothness and can be applied in a thin film.

  • Aqueous coating composition
    Patent number: 5424355
    Abstract: An aqueous coating composition comprising fine polymer particles dispersed in an aqueous medium and an inorganic filler, wherein said fine polymer particles comprise synthetic rubber emulsion polymer particles having a glass transition temperature of 0.degree. C. or less and emulsion polymer particles having a glass transition temperature of 20.degree. C. or more, and further, according to circumstances, urethane emulsion polymer particles. This composition has various properties as a chipping-resistant coating agent in good balance and is particularly useful for coating of the outdoor sheet metal working members of wheeled vehicles.

  • Aqueous dispersion of acrylic polymer
    Patent number: 5405879
    Abstract: An aqueous dispersion of an acrylic polymer comprising acrylic polymer particles dispersed in an aqueous medium in which aqueous dispersion the acrylic polymer particles are composite particles composed of the core part and skin layer part of acrylic polymers having mutually different glass transition temperatures. The aqueous dispersion is useful for preparation of an aqueous coating composition excellent in normal-temperature and low-temperature resistance to chipping.
