Ecological pickling agents for stainless steels

Henkel offers a wide range of processes for the eco-friendly pickling and passivation of stainless steel. BONDERITE C-C is a nitric acid free pickling agent with low hydrofluoric acid, ideal to remove thermal oxides and ensure a clear, homogeneous, and well-passivated surface.

Applied by electrolysis, BONDERITE C-CP EXP is hydrofluoric acid free and guarantees the pickling of stainless steel and superalloys in a very short time.

Advantages:
- lower consumption of pickling chemicals;
- lower quantity of dissolved metals per square meters of pickled steel;
- one pickling solution for all types of steel;
- additional cost-savings thanks to the non-dissolved base alloy;
- no risk of excessive pickling on more sensitive materials;
- considerable longer life of the solutions.

Eco-sustainability:
- reduction of waste and sludge disposal;
- no nitrogen oxide emissions into the air and associated costs;
- reduction of hydrofluoric acid fumes;
- no nitrates in the water;

Henkel's R&D department studies and markets products for the chemical passivation of stainless steel. The BONDERITE® C-CP Bright formula is a cutting edge solution for chemical passivation processes. The less aggressive acid baths provided by this technology result in lower harmful emissions while preserving, enhancing, and improving the surface finish of materials.
