Our new phosphate coating produces a homogeneous, finely crystalline zinc phosphate coating on steel surfaces. This phosphate coating contains, apart from zinc phosphate, other metal phosphates, but no nickel. Hense it is unnecessary to be marked as toxic or hazardous to health....

Cleaning agents containing borate are frequently used for degreasing aluminium or other alkali-sensitive non-ferrous metals. Due to the buffering effect, borates stabilise the pH value of the degreasing solution, as a result of which an attack on materials such as brass or...

The PROSEAL series is a passivation system developed specially for high corrosion protection of zinc and zinc alloys.

The new PROSEAL CF 270 is a cobalt-free thick-film passivation system with a very high corrosion protection that meets automotive standards.

Advantages:

  • Passiv...

PROSEAL NP-300 is a new conversion coating which not only meets the requirements of the EU Directives on Used Vehicles and the RoHS (Reduction of Harmful Substances) concerning the freedom from chromates but even goes a step further. Passivators frequently contain cobalt...

Our new chromium(VI)-free blue passivating agent PROSEAL XZ 130 produces on electroplated zinc surfaces a sparkling blue passive film which is retained even after tempering at 200 °C. Passivation functions at room temperature and thus contributes to energy saving. The blue colour...

Our liquid product removes oxide and scale layers from iron and steel surfaces at pH values between 6.0 to 7.0. In combination with degreasing agents from our SURFACLEAN range it can also be used in case of slight greasing of the work pieces for spray or immersion cleaning. In a...

Our product contains polyfluorinated tensides. These substances are used worldwide in large quantities as successor products to PFOA and/or PFOS and are currently in line with the state of the art. We purchase the raw material for PROQUEL OF from a well-known producer with many...
