Pre-Treatment Products

Combined Cleaner/Etch

Our cleaner/etch product incorporates chemistry that combines both substrate cleaning and etching in one step. Using this product provides our customers with the benefits of  a reduction in operating costs by improving process efficiency and a reduction in waste stream volumes as well.  In addition, it allows our customers to effectively deal with substrate contamination from prior processing steps by providing a more aggressive clean and etch.

Zincate

Conventional zincate solutions are ineffective in meeting the demands of increased production volume as well as the variability of Al substrates currently being plated. Therefore, MacDermid Enthone has developed a more robust zincate formulation that overcomes the variety of issues associated with these different aluminum substrates.

The added value for the customer provided by our unique pre-treatment process is reduced cycle time and increased product throughput.
