Type II Chem Film Applications
Similar to type I chem film, type II is used to coat aluminum to enhance its corrosion resistance and durability. Type II chem film uses a composition that doesn’t contain hexavalent chromium allowing the coating to be RoHS compliant, this coating has no color, and the finished piece looks very much like raw metal. This RoHS compliant chem film service can be used for parts in the medical, aerospace, military, industrial, and energy industries.
Advantages of Type II Chem Film
Consider type II chem film for your aluminum or aluminum alloy components for the following advantages:
- RoHS compliant
