  • Patent number: 8334347
    Abstract: 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.

  • Patent number: 8298441
    Abstract: Stable, phosphorescent, water-based coating compositions include a latex emulsion, at least one metal aluminate pigment as a source of phosphorescence, and an effective buffering amount of a buffering agent, which may be an organic acid. The ratio of metal aluminum phosphorescent pigment to latex binder in the latex emulsion may be in the range of about 0.5:1 to about 2.0:1. The effective amount of buffering agent may be from about 0.1% to about 10% with respect to emulsion weight. Compositions according to the present invention may have useful shelf lives of six months or longer. Methods of using the phosphorescent latex coatings and coated substrates are also taught.

  • Patent number: 8084137
    Abstract: 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.

  • Patent number: 7992330
    Abstract: A display for printed materials includes a pocket mounting panel having a plurality of indexing holes, which may be arranged in columns and rows, and a plurality of pockets adapted to receive printed materials. The pockets include at least one rearwardly extending pocket engaging clip having a resiliently deformable member that is adapted to be received by an indexing hole. Pockets may be installed in a vertically cascading arrangement and individual pockets may be removed from the pocket mounting panel without removing adjacent installed pockets by manually engaging and deforming the resiliently deformable member(s) of the target pocket through access windows provided in the rear panels of the pockets.
