Patent number: 7604837Abstract: A coating composition, particularly a clearcoat composition, which may be a two-component clearcoat composition, comprises a film-forming material, a crosslinking agent, and a nonlinear polysiloxane polymer having a functional group reactive with the crosslinking agent. The coating composition exhibits excellent scratch resistance and adhesion of repair coating layers and sealants, such as windshield sealants.Type: GrantFiled: March 23, 2006Date of Patent: October 20, 2009Assignee: BASF Coatings AGInventors: Thomas C. Balch, David K. Lau, Peter Betz, Gudrun Wiemann, Donald H. Campbell, Vicki Lynn Berry, Kenneth Christopher Fey, John B.

Publication number: 20080171145Abstract: A two-tone painting method includes applying a powder primer to a substrate, followed by a powder basecoat applied dry-on-dry onto the powder primer. The powder basecoat is preferably applied in the same painting booth as the powder primer, i.e., without curing the powder primer. The powder basecoat includes a flake additive, such as a mica flake or a metal flake, which prevents surface irregularities from forming in the powder primer and the powder basecoat as a result of not curing the powder primer before applying the powder basecoat. The substrate is then masked, and a second basecoat is applied. The masking is then removed and a clearcoat is applied. The second basecoat and the clearcoat are then cured simultaneously in an oven.Type: ApplicationFiled: January 15, 2007Publication date: July 17, 2008Applicant: BASF CORPORATIONInventors: Cynthia A. Stants, Thomas C. Balch

Patent number: 6822040Abstract: A basecoat composition includes an acrylic polymer prepared from a combination of monomers including at least about 30% by weight ethyl acrylate, methyl acrylate, methyl methacrylate, or a combination of these. The basecoat composition also includes methylated melamine-formaldehyde resin and up to about 10% by weight of a butylated melamine-formaldehyde resin, based on the weight of the basecoat composition vehicle and butylated melamine resin. An at least partially cured layer of the basecoat composition offers improved adhesion with a coating composition layer applied over it and cured, whether the coating composition layer applied over it is another layer of the basecoat composition itself or a layer of a clearcoat composition.Type: GrantFiled: September 25, 2001Date of Patent: November 23, 2004Assignee: BASF CorporationInventors: Leslie G. Baugh, David K. K. Lau, Thomas C. Balch, Sergio E. Balatan, Walter H. Ohrbom, James A. Laugal, David J. Law

Patent number: 5066732Abstract: This invention, therefore, relates to the field of polyurethane coatings for use in automobile basecoat/clearcoat systems. In particular, this invention relates to water-dispersible polyurethane resins having polyether sidechains which may be utilized in basecoat compositions as principal resins or grind resins. These polyurethane resins may be laterally stabilized or terminally stabilized. The terminally stabilized resins of this invention are preferably employed as principal resins in basecoat compositions.Type: GrantFiled: May 2, 1990Date of Patent: November 19, 1991Assignee: BASF Corporation, Inmont DivisionInventors: Thomas G.
