Completely chrome-free, no hydrogen embrittlement risk, corrosion prevention measures, low-temperature curing, PFAS-free. 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) of over 720 to 2,000 hours, providing proposals tailored to your needs. Additionally, it contains lubricating components and has a stable friction coefficient, making it useful for improving the accuracy of torque management for screws. It has been adopted in various fields, primarily by automotive manufacturers in Europe and the United States. Please feel free to contact us for more details.
