High corrosion-resistant metal surface treatment with a metallic luster, chrome-free and PFAS-free.
This 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 suggested 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 type that does not use hexavalent or trivalent chromium, and is also free of PFAS. ■Chemical Resistance and Anti-Galvanic Corrosion: Minimal damage to the coating from chemicals, effective against galvanic corrosion. ■No Hydrogen Embrittlement Risk: No electrolysis or pickling processes, preventing the 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 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.
