High corrosion-resistant zinc aluminum flake coating containing epoxy resin, excellent weather resistance.
The Disgo treatment is a completely chrome-free high corrosion-resistant treatment that combines a base coat containing zinc aluminum and a top coat primarily made of aluminum and organic resin (epoxy resin). Since there are no acid washing or electrolysis processes, there is no concern about delayed fracture due to hydrogen embrittlement, making it ideal for high-strength, high-carbon components. There is also a low-temperature treatment variation available, which allows for measures against changes in physical properties of the treated materials. Additionally, regarding the repair of coating scratches, using the always-dry repair paint "Draal" can further extend the rust prevention capability.

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.
