Zinc plating + anti-corrosion coating, colorable and high corrosion-resistant composite surface treatment.
This is a high corrosion-resistant surface treatment system that combines a metal zinc plating layer, a special chemical conversion coating layer, and a surface sintering layer. It is a surface treatment that incorporates the advantages of the high hardness coating and edge coverage of zinc plating, as well as the high corrosion resistance and chemical resistance of the paint film. Additionally, it is possible to adjust the paint color to meet your requirements, allowing for discussions regarding color tone and gloss according to the intended use. It can also be used to add color to existing plating or zinc flake coatings. The treatment can be applied to various metals such as iron, stainless steel, and aluminum. For iron, there are types that use standard zinc plating and chromate layers as a base, as well as completely chromium-free types. For stainless steel, it is possible to impart high resistance against weaknesses such as chlorine and electrocorrosion.

Company information
At Kuroiwa Co., Ltd., we perform rust prevention surface treatment processes for metals, including Lafre, Disgo, Raspato, and Delta Protect treatments. Our processing does not involve the use of acids or alkalis, resulting in no wastewater discharge, making it an environmentally friendly closed system method. Additionally, the low-temperature baking treatment minimizes the impact on the material's physical properties, demonstrating our thorough consideration for the environment in our processing technology. We can accommodate surface treatment lots of any size, starting from small-scale prototypes. Furthermore, if requested, we can leverage our network with various manufacturers to handle parts procurement and design, followed by surface treatment processing and delivery. If you have any concerns regarding surface treatment, rust prevention, or parts procurement, we will utilize our experience and know-how to provide you with the best proposals. Please feel free to consult with us.
