Pre-Treatment Products

Combined Cleaner/Etch
Combined cleaner/etch solution incorporates chemistry that performs both substrate cleaning and etching in one step. Utilizing this product enables our customers to reduce operating costs by improving efficiency of their manufacturing process and lowering waste treatment volumes.

9069 is a stronger version of 9068R. It allows our customers to effectively deal with substrate contamination from prior processing steps by providing a more aggressive clean and etch.

Conventional zincate solutions are too mild and ineffective in meeting the demands of increased production volume and use of Al-substrates from different vendors. We have developed a more robust zincate formulation, 9067M, which is able to overcome issues associated with substrate contamination and prevent Al damage. Our customers gain the advantage of a shortened pre-treatment cycle and higher throughput by using this product.
