Idemitsu Kosan Co.,Ltd. Company Overview

Thank you for your continued support. Our long-term rust preventive oil, "Idemitsu Supercoat RS," which achieves improved productivity through water displacement, has recently won the 2025 "Outstanding New Product Award" at the Industrial Cleaning Conference (JICC). This oil successfully combines water displacement (cleaning properties of cutting fluids and grinding fluids) and exposure rust prevention at a high level, which was previously difficult to achieve. Users have praised it for significantly reducing rust, stains, and white residue during rust prevention storage, and for allowing cleaning and rust prevention processes to be done with a single liquid. This recognition is a result of our contribution to the industrial cleaning industry and the technical uniqueness of our product. For those struggling with rust prevention issues between processes, or considering yield improvement and quality enhancement, we encourage you to consider "Idemitsu Supercoat RS" at this opportunity.

"Idemitsu Smart OC" is a technology that allows for easy on-site diagnosis of the degradation and contamination state of lubricants using a smartphone and a photography module. We are pleased to announce that we have received the Good Design Award for the fiscal year 2025. The "Good Design Award," organized by the Japan Design Promotion Association, is Japan's only comprehensive design evaluation and recommendation system. This award places greater importance on innovation than on mere aesthetic beauty, and it has been recognized as an innovation that addresses social issues such as labor shortages and environmental impact reduction. By simply photographing the lubricant contained in the module with a smartphone, it calculates the remaining lifespan percentage and the quantity and size of contaminants. This allows for a data-driven judgment of the appropriate timing for lubricant replacement, contributing to the stable operation of machinery and equipment. [Features and Benefits] ■ Reduction of time and labor for lubricant diagnosis ■ Determination of remaining lifespan percentage based on lubricant color (degradation state) ■ Calculation of the quantity and size of contaminants (contamination state) ■ Contribution to the optimization of lubricant replacement timing Transitioning from TBM (Time-Based Maintenance) to CBM (Condition-Based Maintenance) *Please note that specifications may change without prior notice.
