  • LOW BAKE TEMPERATURE CURABLE COATING COMPOSITIONS AND PROCESSES FOR PRODUCING COATINGS AT LOW BAKE TEMPERATURES
    Publication number: 20150175836
    Abstract: The present invention is directed to a solvent borne low bake curable coating composition having improved sag resistance and coatings properties and process for using the same. The composition includes a crosslinkable component having one or more polymers having two or more crosslinkable groups, a crosslinking component comprising one or more crosslinking agents having crosslinking groups; and a low bake temperature control agent that includes a rheology component and polyurea. When a layer of a pot mix resulting from mixing of the crosslinkable and crosslinking components is applied over a substrate, it has high sag resistance while providing desired coating properties, such as high gloss and rapid cure even under low bake cure conditions. The solvent borne coating compositions is well suited for use in automotive refinish applications as well as industrial applications, such as construction and transportation equipment.

  • Fluorocarbon mediated polymer blends and methods for making thereof
    Patent number: 8236902
    Abstract: The present invention discloses a method for making blended polymers by utilizing fluorophilic inter-polymer associative interactions between perfluorocarbon functional groups attached on the constituent polymers. The method of the present invention is capable of forming blended polymers from otherwise incompatible polymers. Also disclosed are blended polymers obtained by the method thereof. Methods and devices utilizing novel blended polymer of the present invention including chromatography, catalysis, photonic and sensor applications are also provided.
