UniStrip® Rackstrip AF

Ammonia and amine-free electrolytic rack stripper

UniStrip® Rackstrip AF is an effective and fast electrolytic stripper for racks with tips constructed of 301, 304 and 316 stainless steels. It is ideally applied in automatic as well as manual plating lines.

UniStrip® Rackstrip AF is ammonia and amine-free avoiding issues associated with handling ammonium nitrate and restrictions due to the use of amines. The process allows simpler and cheaper wastewater treatment and is formulated to significantly require less COD.

UniStrip® Rackstrip AF generates low amounts of sludge compared to ammonia-based strippers allowing for less frequent and easier bath maintenance.

When copper layers are being stripped from racks, UniStrip® Rackstrip AF’s components can be adjusted in a way that the copper will deposit on the cathodes and can then easily be removed during cathode maintenance. This reduces the metal contamination in the bath prolonging the bath lifetime and reducing the sludge formation at the bottom of the tank.

The mild complexing nature of UniStrip® Rackstrip AF allows for a simple treatment of metal contamination build-ups, which is raising the pH, thus, allowing most of the metal content to precipitate. Metallic particles can then be removed by simple filtration methods. After this treatment process the pH will be readjusted to its operating level for the next stripping sequence.

UniStrip® Rackstrip AF is based on two concentrated liquid products that are easy to use and to handle.

What inspires us

Why we developed UniStrip® Rackstrip AF

Your challenge

Rack maintenance and especially rack stripping is a crucial part of plating processes. Normally rack stripping is performed using strong chemicals like nitric acid or electrolytic rack strippers that contain highly complexing substances like amines and or ammonia. Nitric acid is dangerous for handling, forms toxic NOx gases when stripping, has lower stripping rates for nickel and has short lifetimes. Ammonia and amines in electrolytic rack strippers make wastewater treatment more complicated as the complex has to be broken to enable precipitation of the metals.

Our solution

UniStrip® Rackstrip AF was developed to be ammonia and amine-free and lower in COD compared to common electrolytic rack strippers in use today. This significantly reduces the environmental impact of the process as well as making wastewater treatment and bath maintenance easier and cheaper to perform.
