Low reflection & high light absorption! A deep black electroless plating that demonstrates excellent performance as a paint base.
"Solblack" is an electroless black plating technology that has excellent light absorption performance due to its nano-sized surface irregularities, which create a light trapping effect. It achieves the characteristic of absorbing 97% of visible light without using chromium. With a matte black finish, it does not reflect light and has corrosion resistance superior to that of electroless nickel plating. Additionally, it generates minimal outgassing, making it ideal for use in a vacuum. 【Features】 ■ Superior heat collection compared to black body coatings ■ Excellent heat resistance and light resistance ■ Uniform coating thickness due to the electroless plating method, allowing treatment of complex shapes and inner diameters ■ Does not use environmentally regulated substances such as hexavalent chromium *For more details, please refer to the catalog or feel free to contact us.

Company information
Asahi Precision Co., Ltd. has a purchasing department primarily focused on the processing of precision equipment parts (from ordering parts and materials to processing and assembly) and a surface treatment department that performs plating. In the surface treatment department, we are committed to improving our technical capabilities without compromise, and in recent years, we have received awards such as the Kansai Monozukuri Shin-sen 2017, 2018, and the Kyoto Small and Medium Enterprises Technology Excellence Award 2018. To meet various needs, we are continuously working on the development of original plating technologies that are not available from other companies, and we currently offer over 15 types of special surface treatments. We leverage our unique "technical capabilities" and "know-how" as strengths, and we have established a production system primarily based on plating technicians. Furthermore, we have obtained ISO 14001 certification and are advancing environmentally conscious technology development as part of our management system.
