Highly functional epoxidized resins and coatings
The invention provides highly functional epoxy resins that may be used themselves in coating formulations and applications but which may be further functionalized via ring-opening reactions of the epoxy groups yielding derivative resins with other useful functionalities. The highly functional epoxy resins are synthesized from the epoxidation of vegetable or seed oil esters of polyols having 4 or more hydroxyl groups/molecule. In one embodiment, the polyol is sucrose and the vegetable or seed oil is selected from corn oil, castor oil, soybean oil, safflower oil, sunflower oil, linseed oil, tall oil fatty acid, tung oil, vernonia oil, and mixtures thereof. Methods of making of the epoxy resin and each of its derivative resins are disclosed as are coating compositions and coated objects using each of the resins.
BPA-free coatings
Provided are polytriglyceride-AAG compositions, and corresponding coatings and coated articles. Also provided are methods for preparing the polytriglyceride-AAG compositions, and corresponding reagents including -ketoimide compositions and triglyceride-AAG (acetoacetyl group) compositions. Coatings using the polytriglyceride-AAG compositions may be useful for, e.g., replacing bisphenol-A cross-linked coatings used in food and beverage containers, coating metal articles, and the like.
INK COMPOSITION, PREPARATION METHOD OF THE SAME, AND FABRICATION METHOD OF WINDOW MEMBER USING THE SAME
An ink composition including an epoxy resin, and an amine curing agent. The epoxy resin is formed by reacting a bifunctional epoxy monomer, an adipic acid, and a polyisocyanate. The ink composition is formed by mixing the epoxy resin and the amine curing agent. The preparing of the epoxy resin includes mixing an epoxy functional monomer and an adipic acid to form an epoxy intermediate, and mixing the epoxy intermediate with a polyisocyanate to form the epoxy resin.

EXPANSION POLYMERIZATION IMPRINTING GLUE FOR NANO-PRINTING
An expansion polymerization imprinting glue for nano-imprinting. Raw materials required for the preparation of the expansion polymerization imprinting glue comprise a low polymer and an expansion monomer. Compared with the prior art, after the expansion monomer is introduced into the expansion polymerization imprinting glue for nano-imprinting, the expansion monomer can be polymerized with the low polymer, the volume change of the imprinting glue after polymerization can be adjusted, and accordingly the volume shrinkage after the imprinting glue is cured is reduced or even eliminated; and the imprinting glue having zero curing shrinkage or volume expansion can be obtained by adjusting the content of the expansion monomer. The imprinting glue can effectively reduce the residual stress in a micro-nano pattern, and the generation of pattern defects in the nano-imprinting demolding process caused by the residual stress is reduced while accurate pattern copying is implemented.
