|20120308724||COATING COMPOSITIONS THAT TRANSMIT INFRARED RADIATION AND EXHIBIT COLOR STABILITY AND RELATED COATING SYSTEMS - A coating composition suitable for producing coatings that are transparent to infrared radiation and can exhibit color stability, such as a jet black color. The coating compositions include a first tint having a low haze and a second tint having a high haze. The tints include visibly absorbing infrared transparent pigments.||12-06-2012|
|20120189485||METHODS OF REMOVING RUST FROM A FERROUS METAL-CONTAINING SURFACE - Disclosed are methods for removing rust from a ferrous metal-containing surface. These methods include contacting the surface with a composition that includes a carboxylic acid, a synthetic hectorite clay, and water.||07-26-2012|
|20120088881||LIQUID PIGMENT DISPERSION AND CURATIVE AGENTS - A resin containing a liquid pigment dispersion is disclosed. The dispersion comprises a pigment dispersed in a blend of two or more active hydrogen-containing materials that together have a freezing point that is room temperature or below, The pigment remains dispersed in the blend, even if the dispersion is subjected to freezing and thawing. A curative blend comprising at least two active hydrogen-containing materials, which is liquid at room temperature, is also disclosed. The dispersions and curative blends of the present invention can be solvent-free. Resins and prepolymers comprising the curative blends of the invention, either pigmented or unpigmented, are also disclosed.||04-12-2012|
|20110294942||PIGMENT DISPERSIONS, RELATED COATING COMPOSITIONS AND COATED SUBSTRATES - Disclosed are pigment dispersions and coating compositions that include such pigment dispersions. The pigment dispersions include: (a) a pigment; (b) an acid functional, hydroxyl functional and secondary amine functional acrylic polymer having a weight average molecular weight of at least 11,000; and (c) a liquid carrier comprising an organic solvent.||12-01-2011|
|20110236673||COATED ARTICLES AND MULTI-LAYER COATINGS - Articles are disclosed wherein a color-imparting non-hiding coating layer is deposited on a surface thereof.
