Latest Patents

Won S Kim holds a patent for a process for preparing hydroxyl polyester for use in powder coatings. This patent describes a crystalline polyester resin derived from the reaction between a prepolymer and trimellitic anhydride. The prepolymer is formed from an alcohol mixture containing at least 40 mole % ethylene glycol and at least 30 mole % neopentyl glycol, along with an acid mixture that includes terephthalic acid or dimethyl terephthalate. The resulting crystalline polyester resin is characterized by a hydroxyl number of 20 to 100, an average molecular weight of 1000 to 3500, and a melt viscosity at 160°C of 500 to 4000 cps. This resin is particularly suitable for use in powder coating compositions due to its dense, regular, and repetitive structure.
