With Gardolene®, we offer a wide range of ultra-efficient technologies. Our products are available in liquid form and as powders and are excellently suited for treating substrates made from steel, zinc, aluminum and their alloys.

In most pretreatment processes, activation is used prior to phosphating. Activation allows for the formation of finely crystalline zinc-phosphate layers.Our activating agents contribute to generate finely crystalline layers and shortening the time required to obtain a uniform, coherent coating during the treatment with phosphating solutions.

After zinc-phosphating, another protective process in the form of a passivation can be applied to the metallic parts. Our passivating agents Gardolene® D enhance corrosion protection and contribute to an excellent adhesive substrate for downstream process steps, like for example painting. Chrome-free technologies on the basis of zirconium or titanium fluoride are available.
