Patent number: 8334347Abstract: A 2K basecoat clearcoat system includes a solvent borne basecoat having a low Tg branched polyester polyol, optionally, a high Tg, high molecular weight thermoplastic resin, and a hardener that includes an isocyanate functional material suitable for crosslinking the polyester polyol, and optional thermoplastic resin. The solvent borne clearcoat composition includes a low Tg linear or branched polyester polyol, at least one other multi-functional polyol, and an isocyanate functional material suitable for crosslinking the polyester and multi-functional polyols.Type: GrantFiled: February 10, 2010Date of Patent: December 18, 2012Assignee: The Sherwin-Williams CompanyInventors: Hong Ding, Zhicheng Li, Weilin Tang, Ganesh S. Desai, Thomas J. Staunton, Brian J. Wayton, Heather N. Becker, Prabhjot K. Sahota

Publication number: 20120308830Abstract: A coating system for application to a substrate having a sol-gel film layer applied thereon includes a residual high acid value coating coat applied on top of the sol-gel film without an intervening adhesion layer. The residual high acid value coating composition may be a solvent borne composition that when cured, has a high level of residual free acid groups, equivalent to an acid number of greater than about 65 mgKOH/g. The residual high acid value coating may include a residual high acid value resin namely, a resin that cures having residual free acid groups, equivalent to an acid number of greater than about 65 mgKOH/g. The residual high acid value resin may be the reaction product of a polyol and a suitable crosslinker, such as a polyanhydride or polyisocyanate crosslinker or blend thereof. The residual high acid value coating composition may include opacifying pigments and condensation catalysts.Type: ApplicationFiled: May 16, 2012Publication date: December 6, 2012Applicant: THE SHERWIN-WILLIAMS COMPANYInventor: Brian J. Wayton

Publication number: 20120301726Abstract: A coating system for application to a substrate having a sol-gel film layer applied thereon includes a decorative color coat applied directly on top of the sol-gel film without an intervening adhesion layer. The decorative color coat may be a solvent borne composition including a resin which is the reaction product of a crosslinked polyepoxy resin and a polyamine crosslinker, and one or more opacifying pigments. Decorative designs may be formed by selectively applying more than one layer of decorative color coats having different colors. A transparent clearcoat may be applied to the decorative film.Type: ApplicationFiled: May 15, 2012Publication date: November 29, 2012Applicant: THE SHERWIN-WILLIAMS COMPANYInventors: Thomas J. Staunton, Weilin Tang, Brian J. Wayton

Patent number: 8084137Abstract: The present invention provides for a resin system and coating composition suitable for direct application to metal substrates. The composition may include a phosphate functional polyester. The polyester may be an unsaturated polyester polyol. The coating composition may further include a suitable curing agent, such as an isocyanate or melamine. The composition can be applied through traditional application equipment onto a variety of metal substrates and cures to an acceptable surface for further processing, such as top coating with basecoat and clearcoat.Type: GrantFiled: January 9, 2009Date of Patent: December 27, 2011Assignee: The Sherwin-Williams CompanyInventors: Hong Ding, Brian J. Wayton, Weilin Tang

Publication number: 20100160537Abstract: The present invention provides for a sealer/primer that is generally cured at low bake temperatures. The composition utilizes a resin system to provide both conductivity and adhesion of the coating onto plastic substrates. The present invention uses a polyester, such as one that includes unsaturated polyester, in combination with other resins, including an acrylic, crosslinking agent and conductive pigment to create a conductive primer that can be cured at low temperatures. The composition can be applied through traditional application equipment, seals the surface of the substrate to which it is applied, and cures to an acceptable surface for further processing, such as painting.Type: ApplicationFiled: April 13, 2009Publication date: June 24, 2010Applicant: THE SHERWIN-WILLIAMS COMPANYInventors: Brian J. Wayton, Hong Ding, Michael W. Cox
