The difficult-to-remove carbides (hard carbon) attached to the EGR cooler were cleaned by crushing them with tools such as drills. "KST-AL" was developed to clean the carbon attached to aluminum EGR coolers. This document introduces the product's cleaning tests. As a preliminary test, we used a motorcycle piston to confirm aluminum corrosion and to check the carbon stain removal processing time and processing temperature.

This document introduces the adhesive peeling verification for the mesh frames used in silk screen printing. Since aggressive liquids (acidic, alkaline aqueous or semi-aqueous solutions) cannot be used on the aluminum material being adhered, we considered using organic solvent-based peeling agents. Additionally, chloroprene rubber-based adhesives are very hard yet have excellent flexibility, and we believe that agents capable of both dissolving and peeling are appropriate, leading us to engage in research and development.

KST Corporation was founded in September 1988, inspired by our participation in the development of domestically produced rockets. Focusing on special cleaning and pressure-tightness testing, we have established our know-how with the motto "Zero defective outflow and nonconformities!" Currently, we have expanded our business to include various contracted testing, design and manufacturing of jigs, production and assembly of aerospace equipment parts, manufacturing and maintenance of high-pressure gas facilities, as well as the development and production of cleaning agents. 【Business Activities (Partial)】 ■ Cleaning of rocket parts and development support ■ Pressure leakage testing of aircraft parts and industrial equipment parts, as well as development support ■ Installation, development, and manufacturing sales of aerospace-related jigs ■ Design, manufacturing, assembly, and repair of space equipment parts ■ Installation, manufacturing, and sales of thermal insulation materials for machines ■ Development and manufacturing of cleaning agents *For more details, please refer to the PDF document or feel free to contact us.

• Mechanical Design

We would like to introduce KST Corporation's research and development products. Starting with the grease and paint marker cleaner "KST-50," we have developed chemical polishing liquids for metal (maraging steel) 3D printer molded products, "KST-70," and precision cleaning agents for aerospace components, "KST-100." If you provide us with samples of the dirt, we will consider the development of cleaning agents and methods to solve the issue. Please feel free to consult us when needed. 【Development Products (Excerpt)】 ■ "KST-75・85" Cleaning agents for dust collection filters for metal (maraging steel, SUS316) 3D printers ■ "KST-250 DPF" Cleaning agents specifically for truck and automotive exhaust catalyst DPF ■ "KST-EGR" Cleaning agents for truck EGR coolers ■ "KST3900・4200 Series" Coating stripping agents for painting jigs ■ "AsTORN" Asphalt pitch removal agents *For more details, please refer to the PDF materials or feel free to contact us.

Water-based cleaning, used for industrial parts, precision parts, and clean parts, has traditionally been considered less effective against oil stains compared to solvent-based cleaning. Our company has successfully combined a newly developed water-based cleaning agent with our cleaning method, significantly improving cleaning power compared to conventional water-based cleaning. The target work includes industrial parts, precision parts, clean parts, and more, with additional options available. Please feel free to contact us. 【Features】 ■ Highly effective against oil stains ■ Considerate of the environment and workers ■ Easy rinsing *For more details, please refer to the PDF document or feel free to contact us.
