High corrosion-resistant metal surface treatment with a metallic luster.
It is a chrome-free coating with a rich metallic luster. By using high corrosion-resistant zinc flake paint or zinc plating as a base, it is possible to adjust corrosion resistance. With its glossy and sharp surface, it can also be proposed as a replacement for stainless steel to iron materials.

basic information
■Corrosion Resistance: Salt spray test shows red rust for over 1,000 to 2,000 hours. ■Environmentally Friendly: Completely chrome-free, without the use of hexavalent or trivalent chromium. ■Chemical Resistance and Electrolytic Corrosion Resistance: Minimal damage to the coating from chemicals, effective against electrolytic corrosion. ■No Hydrogen Embrittlement Risk: No electrolysis or pickling processes, no occurrence of hydrogen embrittlement. ■Low-Temperature Treatment: Low-temperature curing at 200 to 250°C minimizes changes in the physical properties of the treated items. Regarding surface treatment lots, we can accommodate even small-scale prototypes regardless of size. Additionally, if requested, we can handle parts procurement, perform surface treatment processing, and provide the finished products. Please feel free to consult with us.

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.
