ZWEZ-Clean /-Acid /-Oil

Degreasing, cleaning, decoating, derusting, descaling, pickling

The ZWEZ-products for pre- and post-treatment are specifically designed for the demands of the ZWEZ-Coat and ZWEZ-blackening processes and thus guarantee the highest possible quality standard for the coatings.

ZWEZ-Clean cleans and degreases with special effects, which are necessary for the coating and de-coating of formed parts. ZWEZ-Clean is distinguished by low application temperature and bath concentration, as well as by long bath life-time and suitability for micro-filtration.

ZWEZ-Acid removes oxidic impurities quickly and thoroughly while protecting the raw metal. This product range harmonises well with the process chain of the ZWEZ-Coat or ZWEZ black coatings. Special ZWEZ-Acid-Additives for pickling, degreasing and inhibiting complement this range of products.

ZWEZ-Oil is a conservation system used as a final treatment. The coating is carried out in an aqueous solution (Emulsion; ZWEZ-Oil E) or in a solvent on petrol basis (ZWEZ-Oil D). Whether thick or thin, hard or soft, suitable for every demand and types of application. For removing these coatings, ZWEZ-Clean products are to be used, as these products are specifically designed for such applications.

Extra-specially formulated ZWEZ-Clean/ZWEZ-Acid-products are designed for residue-free removal of all kinds of lubricant types and carrier films. By means of their distinctive properties, they can cleanse formed parts, wires and pipes within shortest time. They thus guarantee a trouble-free processing.

The special processes for alkaline treatment such as ZWEZ-Clean: cleansing, degreasing, decoating and acidic treatment, such as ZWEZ-Acid: derusting, descaling, decoating, perfectly fulfill the very different cleansing tasks.

Special products for pre- and post-treatment optimise these processes:

  • ZWEZ-Clean ADD for microfiltration
  • ZWEZ-Acid inhibitors for all mineral acids
  • ZWEZ-Acid pickling degreaser
  • ZWEZ-Rinse for neutralising and passivating post-treatment
