"ERIN" is a completely chrome-free surface treatment that does not use "hexavalent chromium," which is a cause of environmental burden. It excels in adhesion, rust resistance, and wear resistance, and can form a film on various substrates. <Examples of Compatibility> Iron, Aluminum, Copper, Stainless Steel, etc. Additionally, as it is a coating developed based on the phenomenon of room temperature impact curing, there is no thermal assistance during film formation. Raw material particles collide with the substrate at high speed, crushing and deforming to form a dense and smooth film without voids. 【Features】 ■ Improved wear resistance (1-3μm) ■ Coating hardness (HV1000-1200) ■ Insulating coating ■ No distortion or dimensional changes due to heat, as it is a room temperature treatment ■ Heat resistance (−70 to 750°C: coating) *For more details, please refer to the PDF document or feel free to contact us.

"ERIN" is a completely chrome-free surface treatment that does not use "hexavalent chromium," which is a cause of environmental burden. Developed based on the phenomenon of room temperature shock curing, this new coating does not require a heat treatment process. Raw material particles collide with the substrate at high speed, crushing and deforming to form a dense and smooth film without voids. If you are experiencing issues with distortion or dimensional changes due to heat in your surface treatment process, please feel free to consult us. 【Features】 ■ No distortion or dimensional changes due to heat during room temperature treatment: no material changes ■ Improved wear resistance (1-3μm) ■ Excellent thin-film rust prevention ability (1-6μm) ■ Heat resistance (−70 to 750℃: coating) ■ Coating hardness (HV1000-1200) ■ Insulating coating *For more details, please refer to the PDF document or feel free to contact us.

-------------------------------------------------------- Free Comprehensive Catalog Giveaway!! -------------------------------------------------------- A pellet stove is a heating device that uses biomass energy in the form of "wood pellets" as fuel. Right now, we are offering a comprehensive catalog for free. Pellet stoves are not just stylish, solid, and luxurious. They are also easy to handle, allowing you to easily see the flames and enjoy a soothing moment. However, the most important aspect is that they can be used in a way that is "kind to the Earth's environment and people." The pellets used as fuel are a renewable clean energy source that utilizes forest resources and do not contribute to the increase of CO2, which is the largest factor in global warming. Furthermore, pellet stoves are easy to handle for women and the elderly, making them a manageable energy source in terms of ignition and fire safety. ● For more details, please download the catalog or contact us.

A resident film is formed on the surface of the base material, while also diffusing into the uppermost part of the base material. The rust prevention effect at 1μ is unprecedented. However, similar to zinc-based systems, oil application and other measures are necessary for a period of 70 to 90 days until the oxygen molecules between the film layers become inert. After this period, an alloy layer forms on the base material, resulting in a robust coating. The advantages of rust prevention effects with a precision of 1±0.3μ are primarily utilized in the treatment of precision machine parts such as linear guide rails, bearings, and fitting components.
