Features of Silvec's aluminum chemical treatment
Regarding the specified chemicals for trivalent chromium-based aluminum conversion treatment There are many types of trivalent chromium-based aluminum conversion treatment chemicals available from various surface treatment chemical manufacturers. Our company selects treatment chemicals after conducting repeated tests with various changes in aluminum types, treatment conditions, and other factors from each surface treatment chemical manufacturer. While there are chemicals that are almost equivalent to those selected by our company, we establish the highest quality chemicals and treatment conditions suitable for our customers' intended use and specified specifications. As a standard for equivalent levels, we consider chemicals that can clear SST72h-RN9.5 or higher with trivalent chromium-based conversion treatment on ADC12 to be at an equivalent level. Since it is die-casting, the results may vary depending on the condition of the casting surface. Therefore, we conducted tests using test pieces that reproduced almost the same casting surface with various chemicals and conditions. Please understand that while there may be other chemicals that can meet the criteria listed below, our company does not test all chemicals.

basic information
【Aluminum Conversion Treatment】 This is an aluminum conversion treatment compliant with the RoHS directive. Aluminum conversion treatment is a technology that precipitates a highly corrosion-resistant film on aluminum through a chemical reaction. This conversion film is highly resistant to corrosion and is often used as a primer for painting to improve paint adhesion and enhance the corrosion resistance of the paint film. Our company can accommodate both trivalent chromium direct chromate conversion treatment and non-chromium zirconium conversion treatment. Our trivalent chromium conversion treatment can meet the specifications of several types of chemical solutions commonly specified by automotive parts manufacturers.
