Completely chrome-free, no hydrogen embrittlement risk, anti-electrolysis measures, low-temperature baking; ideal for rust prevention of screws, nuts, washers, and small pressed parts.
This is a high corrosion-resistant, completely chrome-free zinc-aluminum flake surface treatment. In addition to a thin and uniform coating, the combination of a rich base coat and top coat allows for corrosion resistance in salt spray tests (SST) ranging from red rust for over 720 to 2,000 hours, enabling us to provide optimal proposals tailored to your needs. Additionally, because it contains lubricating components, it is also possible to adjust the friction coefficient, which can improve the accuracy of torque management for screws. We have a proven track record of adoption primarily among automotive manufacturers in Europe and the United States, as well as in various other fields.

Detailed information
-
Silver Type: Standard type for internal lubrication. It features a high corrosion-resistant two-coat, two-bake treatment with a base coat of zinc-aluminum composite film topped with a silver top coat. ● Organic, solvent-based coating containing aluminum ● Contains lubricants to adjust the friction coefficient ● Excellent high corrosion resistance, particularly in chemical resistance ● Effective against galvanic corrosion (dissimilar metal contact corrosion) ● Applicable to all materials such as iron, stainless steel, and aluminum
-
Black Type: It has a semi-matte finish and a uniform appearance. In addition to corrosion resistance, it excels in UV resistance. This coating combines a zinc-aluminum composite base coat with an organic, solvent-based top coat that has excellent coverage in black. ● Excellent resistance to galvanic corrosion (dissimilar metal contact corrosion) ● Superior UV resistance, chemical resistance, and adhesion ● Features a smooth black appearance with a semi-matte finish ● Contains lubricants to adjust the friction coefficient ● Can be applied to all materials, including iron, stainless steel, and aluminum.
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.
