Title: Innovative Contributions of Takashige Kato in Polyester Resin Technology
Introduction: Takashige Kato, an esteemed inventor based in Okazaki, Japan, is recognized for his significant contributions to polymer technology. With a strong portfolio that includes two notable patents, Kato has specialized in the development of polyester resin compositions that have advanced the field of powder paints.
Latest Patents: Kato's latest patents exhibit his expertise in creating polyester resin compositions suitable for high-performance powder coatings. His first patent describes a polyester resin composition that can be obtained by mixing a polyester (derived from a high degree of polymerization) with at least one nonvolatile alcohol or an ester with alcoholic hydroxyl groups. This innovative composition melts at temperatures ranging from 45°C to 120°C, featuring terminal hydroxyl groups and a degree of polymerization between 5 and 50. It is noted for its pulverizability, lack of blocking properties, and fluidity at relatively low temperatures, allowing for efficient pigmentation and the formation of aesthetically pleasing coatings. Additionally, these coatings demonstrate excellent resistance to weathering, solvents, humidity, and fouling, along with superior adhesion to metal surfaces.
The second patent highlights another polyester resin composition, where a molten polyester with an average degree of polymerization of 5 to 50—primarily comprising terephthalic acid, p-hydroxybenzoic acid, and ethylene glycol—is mixed with various hardeners. Like the first, this composition is tailored for powder paint preparation, presenting ease in pulverization, and remarkable attributes such as excellent weather and solvent resistance, antifouling properties, and intimate adhesion to metals.
