Cation electrodeposition coating for rust prevention of aluminum die-cast ADC12.
About Silvec's aluminum die-cast ADC12 cationic electrodeposition coating.
■ Corrosion Prevention for Aluminum Die Casting ADC12: Surface Treatment for Rust Prevention Silvec has extensive know-how in rust prevention treatments for aluminum die casting ADC12 and can provide original technology solutions. ■ Corrosion Resistance and Surface Treatment of Aluminum Die Casting ADC12 Aluminum die casting ADC12 is widely used, accounting for over 90% of production ratios among aluminum die casting alloys, due to its excellent castability, mechanical properties, and machinability. However, its corrosion resistance is relatively poor compared to other aluminum die casting materials, necessitating rust prevention treatments depending on the application. The four representative treatments for rust prevention of aluminum die casting ADC12 are as follows: 1. Plating 2. Anodizing 3. Chemical treatment (trivalent chromate treatment) 4. Cationic electrodeposition coating
basic information
The coating process involves immersing the product in a water-soluble electrodeposition paint and applying current as a negative electrode to adhere the paint. The characteristics of the coating film are: ■ Minimal paint unevenness even on complex shapes ■ Relatively uniform film thickness ■ Little occurrence of pinholes ■ High adhesion of the coating film
