Utilizing the metal processing technology accumulated over more than half a century, we are realizing technological innovation in various material processing areas

Our metalworking chemicals are widely used for wire and tube drawing, cold rolling, pressing, and casting, slicing, and lapping for the metal forming industry. Our metal surface treatment chemicals are also widely used for cleaning metal, rust preventing, derusting metal, antistatic application and so on. Kyoeisha Chemical has earned the highest share in the Japanese market with the wire drawing lubricant know as “KOSHIN”. We strive to develop products that provide superior performance while addressing today’s critical environmental concerns. For example, we produce environmental friendly rust-preventive agents for fuel tanks used in cars, ships and rockets, and for boilers in thermal power plants. And for silicon wafer processing in the semiconductor production field, we provide chemicals that produce no endocrine disrupters – substances that pose significant risk to the environment.

Application Product
Pretreatment Agent LIGHT COAT
The pretreatment chemicals work as a career to draw wire through a drawing die by forming an uneven surface coat on the wire surface. Also, the lubricants are trapped in the uneven surface and, together, form a lubricating film.
Wire Drawing Lubricant (Dry) KOSHIN
Forms the ideal lubricating film between the wire and the die to make the plastic deformation easy, while reducing the consumed energy required for drawing, suppressing the heat from friction, and stabilizing product quality.
Wire Drawing Lubricant (Wet) METALSHIN LS Series (Oil-based), METALSHIN N Series (Soluble), ANILIGHT (Soluble)
The wet drawing lubricant is used for thin wire, low carbon steel wire, and copper wire, and it comes in oil-based or water-soluble types.
Application Product
Metal Detergent LIGHT CLEAN (Alkaline, Acidic, and Solvent Based)
Removes cutting fluid, lubricating oil, grease, and wire drawing lubricant (KOSHIN) attached to metallic surfaces.
Neutral Deruster RUST VULTURE
Remove rust from metallic surfaces through dipping or circulating without using hydrochloric acid or sulfuric acid (hazardous substances).
Application Product
Oil Based Rust Inhibitors RUSMIN KP Series
Oil Based Corrosion Inhibitor can provide long term corrosion protection.
Volatile Rust Inhibitors RUSMIN V Series
Corrosion inhibiting vapor gas protects against corrosion in airtight spaces. It also eliminates the need for removal before moving to the next process in manufacturing.
Water Based Rust Inhibitors RUSMIN W, MK Series
Provides corrosion protection by adding a small amount in a water pressure tests, coolant water, and full water storage. Compatible with the Japanese water emissions standard for low level pollutants.
