What is Paint-Wetting Impairment Substances (PWIS) ?

Paint-Wetting Impairment Substances (PWIS)

Examples of such substances are oils, greases, fluoride, waxes and silicone.

They negatively affect painting processes and are not allowed in the automotive industry and other production plants.

A thin oil-film is usually present on the steel coils we purchase and additional lubrication is often necessary for the roll-forming and stamping processes.

The protective foil of several self-adhesive gaskets also contains some silicone (see also the additional information ZI-201, 202, 206, 210, ...).

In view of the above we cannot guarantee that our products are totally PWIS-free
