Title: The Innovations of Natsumi Kimura: A Pioneer in Coating Technology

Introduction: Natsumi Kimura, an accomplished inventor based in Kanagawa, Japan, has made significant contributions to the field of engineering, particularly in oil seal technologies and cleaning components. With a remarkable portfolio of eight patents, Kimura's innovations demonstrate a keen understanding of material science and mechanical engineering.

Latest Patents: Among her latest contributions is a revolutionary coating agent for oil seals. This innovative formulation comprises 10 to 160 parts by weight of a filler with a particle size of 0.5 to 30 µm, mixed with 100 parts by weight of isocyanate group-containing 1,2-polybutadiene, and prepared as an organic solvent solution. Notably, this coating agent achieves a contact angle of less than 35° between the coated substrate surface and engine oil, which improves wettability and reduces the dynamic friction coefficient. Furthermore, it enhances the roughness of the coating surface, thereby achieving low torque characteristics while maintaining excellent seal performance inherent in oil seals.

Another groundbreaking patent that Kimura has developed is a unique cleaning blade. This device features an elastic body made from a molded rubber material that incorporates a surface treatment layer within the portion intended to contact targeted objects. The surface treatment layer is formulated by impregnating a portion of the elastic body with a liquid containing an isocyanate compound and an organic solvent, ensuring the layer retains an elastic modulus of 95 MPa or less. The overall elasticity of the cleaning blade is optimized with a difference in modulus of at least 1 MPa between the surface treatment layer and the elastic body, which enhances its effectiveness in various cleaning applications.

Career Highlights: Natsumi Kimura has held pivotal roles in esteemed organizations, including Nok Corporation and Synztec Co., Ltd.
