Company News A Better Alternative to Nickel Sealing

The Responsible Anodizer's Choice: Tested and Proven to Work Safely and Effectively

Anodal ES-1 is Clariant's patented non-nickel seal with over 20 years of proven production. Because Anodal ES-1 contains no regulated metal and is relatively pH neutral, waste treatment is simpler, easier and cheaper compared to using a nickel-based seal.

Anodal ES-1 can be applied alone or as the final seal in a two-step sealing system.

The concentration of the Anodal ES-1 seal for job shop applications is lowered to allow a more frequent, yet economic tank replacement while providing a fresh seal solution. This is particularly helpful in bright dip shops where phosphate contamination is the usual reason for seal tank replacement. Bath life can be extended by the addition of Clariant’s Anodal MS-1A.
