The passivation film formed by 216 exhibits excellent thermal stability, withstanding temperatures up to 200°C without degradation. This property ensures the coating remains intact and functional even in high-temperature environments, making it suitable for engine parts, exhaust systems, and other heat-exposed components. The process is user-friendly and straightforward, requiring only immersion in the 216 solution to form a bright, uniform, and aesthetically pleasing iridescent film.

The film produced by 216 is characterized by its vibrant and diverse color spectrum, including shades of yellow, blue, purple, and red. This versatility allows for customization to meet specific aesthetic or branding requirements. The solution is compatible with various zinc plating processes, including cyanide zinc plating, alkaline zinc plating, and acid zinc plating, ensuring broad applicability across different manufacturing setups.

In addition to its visual appeal, the 216 passivation film provides enhanced corrosion resistance, improved adhesion for subsequent coatings, and increased surface hardness. It is also environmentally friendly, as it eliminates the use of hexavalent chromium, aligning with global regulations and sustainability goals. The process is highly efficient, with fast treatment times and minimal waste generation, making it suitable for both batch and continuous production lines.

Overall, 216 represents a cutting-edge solution for achieving high-quality, durable, and visually striking passivation films on zinc-coated substrates. Its combination of superior performance, ease of operation, and environmental compliance makes it a preferred choice for industries seeking to enhance both the functional and aesthetic properties of their products.
