The products have excellent physical properties, including a high degree of weatherability. They may be blended with other polymers such as polycarbonates, poly(alkylene dicarboxylates), polyarylates, polyetherimides, and addition polymers to improve the weatherability thereof.Type: ApplicationFiled: January 3, 2001Publication date: August 23, 2001Inventors: Peter Hendrikus Theodorus Vollenberg, Hongyi Zhou, Bimal Ramesh Patel

Patent number: 6270855Abstract: Powder coating compositions for metal substrates, a method of powder coating a metal substrate, and a metal article are disclosed. The powder coating composition is a thermoplastic material and comprises: (a) a first polyester having a weight average molecular weight of about 10,000 to about 80,000 and a Tg of greater than 45° C. to about 100° C., (b) a second polyester having a weight average molecular weight of about 10,000 to about 70,000 and a Tg of about −10° C. to about 45° C., and optionally, (c) a modifying resin, such as an epoxy resin having an epoxy equivalent weight of about 500 to about 15,000, wherein the Tg of the first and second polyesters differ by about 5 ° C. to about 60 ° C. The powder coating composition is applied to a metal substrate to provide a composition film having a thickness of about 1 to about 200 microns.Type: GrantFiled: March 16, 1999Date of Patent: August 7, 2001Assignee: The Valspar CorporationInventors: Rolf Jung, Christian Schmid

Patent number: 6251999Abstract: A catalytic tin carboxylate adduct, which is useful as a catalyst in epoxy-acid coating compositions, is the reaction product of (A) a mono-, di-, or poly-carboxylic acid functional compound and (B) an organotin compound containing one to three aryl groups and at least one halogen or hydroxyl group attached to the tin atom. There is also provided an epoxy-acid coating composition, which incorporates this catalytic tin carboxylate adduct. The epoxy-acid coating composition is advantageous as an automotive topcoat, particularly as a clear coat composition because it exhibits good appearance, durability, stability and generates no, or extremely low levels of benzene during the curing process.Type: GrantFiled: June 23, 1999Date of Patent: June 26, 2001Assignee: PPG Industries Ohio, Inc.Inventors: Daniel E. Rardon, Kurt A. Humbert, Karen A. Barkac, Peter Kamarchik, Jr., Mark E. Wozniak
