E-Pik 217-L is a mildly acidic liquid mixture, which works at room temperature to prepare copper surfaces for finishing with EPi's blackening, antiquing, and electroplating processes.

E-Pik 217-L Copper Etchant and Activator
E-Pik 217-L is created for the preparation of copper surfaces for use with EPi's electroplating processes. It does not produce undesirable fumes, so no venting is required when using at room temperature.
E-Pik 217-L is more moderate in its action than mineral acids and peroxide, and produces a defined etch profile and a very consistent surface area. It leaves a moderately passive surface resistant to rapid re-oxidation allowing for greater time flexibility for subsequent finishing operations. Another benefit is that it does not contain phosphate, chromate, nitrate, fluoride, chloride, or ammonia.
