  • Patent number: 8323525
    Abstract: 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.

  • Patent number: 7872078
    Abstract: The present invention is directed to curable film-forming compositions comprising: (a) a polymeric binder comprising a polyester having hydroxyl functional groups; and (b) a curing agent comprising a polyisocyanate having at least three isocyanate functional groups. In certain embodiments, after application to a substrate as a coating and after curing, the compositions demonstrate a Fisher microhardness of at least 120 at ambient temperatures of 15 to 25° C. and a softening point greater than or equal to 35° C. Additionally, in certain embodiments, after application to a substrate as a coating and after curing, the compositions demonstrate a 20° gloss recovery of at least 75% when subjected to the DRY ABRASION TEST METHOD.

  • Publication number: 20090239043
    Abstract: Oleophilic compositions, coatings employing the same, and devices formed therefrom that exhibit one or more improved coating properties. The compositions may comprise a film-forming binder and, when at least partially coated and cured on a substrate, comprise: (a) a contact angle with water ranging from 50 to less than 78; and (b) a contact angle with squalene of less than 25. The coating compositions may include various binder compositions, including, for example, thermosetting acrylic polymers, thermoplastic acrylic polymers, radiation curable coating compositions, and alkoxide compositions. The resultant coatings exhibit one or more improved physical properties, such as improved gloss, improved stain and sebum resistance, and/or improved cleaning ability relative to existing coating systems when deposited over various substrates.
