Patent number: 6861467Abstract: A powder coating composition contains a binder component of either a silicone resin or a mixture of a silicone resin and at least one selected from the group consisting of an epoxy resin, a phenolic resin, an acrylic resin, a polyester resin, and a fluororesin; and a reinforcing pigment of at least one of a mica and a whisker, wherein the content of the silicone resin in the binder component is at least 60% by weight. Such a composition can be free from the occurrence of the paint film cracks and peeling under heat at a high temperature of 300° C. or higher and can have good heat-resistant adhesion. Therefore, the present invention provides a powder coating composition which is excellent in heat-resistant adhesion at a high temperature of 300° C.Type: GrantFiled: June 25, 2003Date of Patent: March 1, 2005Assignee: Okitsumo IncorporatedInventor: Hiroshi Nakano

Patent number: 6852768Abstract: The invention provides curable organic coatings with improved scratch resistance. More particularly, the present invention relates to a combination of inorganic filler having a 50th percentile particle diameter of from about 3 to about 9 micrometers comprised of aluminum oxide, silicon dioxide, ceramic spheres or mixtures thereof, and particles having a 50th percentile particle diameter of from about 10 to about 150 micrometers. The liquid coatings have a viscosity before curing of from about 100 cps (mPa-s) to about 70,000 cps (mPa-s) at a shear rate of 0.15 s?1. The use of inorganic filler materials of the defined type and particle size are combined with the curable organic coating to improve the scratch resistance of the coating without a negative impact on the physical and performance properties or application parameters of the original coating material.Type: GrantFiled: October 3, 2002Date of Patent: February 8, 2005Assignee: Lord CorporationInventors: Pei Wen Jin, Kimberly R. Benca, Ian C. Quarmby, Thomas Kurpiewski, Victor E. Ferrell
