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 metallic zinc plating layer, a special chemical conversion coating layer, and a surface sintering layer. It features the advantages of a high-hardness coating from zinc plating and excellent edge coverage, along with high corrosion resistance and chemical resistance of the coating. 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 based on conventional zinc plating with a chromate layer, as well as completely chromium-free types. For stainless steel, it can provide high resistance to weaknesses such as chlorine and electrolytic corrosion.

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 any steps using acids or alkalis, resulting in no wastewater generation, making it an environmentally friendly closed system method. Additionally, due to the low-temperature baking treatment, there is minimal impact on the material properties, demonstrating our thorough consideration for the environment in our processing technology. We can accommodate surface treatment lots of any size, starting from small prototype quantities. Samples of treated products can be shipped free of charge. Furthermore, if requested, we can leverage our network with various manufacturers to handle parts procurement, perform surface treatment, and provide the finished products, or procure individual parts as needed. If you have any concerns regarding surface treatment, rust prevention, or parts procurement, we will utilize our experience and know-how to provide optimal proposals. Please feel free to consult with us.
