Excellent thin film black chrome plating treatment with good paint adhesion, ideal as a base for painting!
A thin film coating with a deep black finish is obtained, featuring excellent corrosion resistance: "High Black" thin film black chrome plating. ● Thin film black chrome plating "High Black I" ● RoHS-compliant "High Black II" that reduces and cleans hexavalent chromium ● "Techno High Black," which coats the surface of the "High Black" film with fluororesin (RoHS compliance available) It can be applied to iron, stainless steel, copper, and copper alloys, offering excellent adhesion, corrosion resistance, and heat resistance. 《 Features 》 - The plating film has numerous pores, providing excellent oil retention. In an oil-retained state, there is no discoloration or corrosion even after 100 hours of salt spray testing (JIS Z 2371). - Being a thin film, there is no need to consider the thickness of the plating film during machining. - Direct application is possible without a base plating. - It efficiently absorbs sunlight and generates minimal infrared radiation. - It has heat resistance, showing no change in appearance even when heated to 300°C. - It has good paint adhesion (extremely suitable as a base for painting). - The average reflectance in the visible light range is 2-3%. * For more details, please download the PDF or feel free to contact us.
