Ulamo Coating specialises in high-grade chromium-free chemical pre-treatment of aluminium, bare steel, stainless steel and hot-dip galvanised steel. Chromium-free pre-treatment is done with a multimetal spray tank treatment. This installation offers excellent flexibility; large and small products can be processed at the same time, as well as large and small series. Ulamo Coating also has a special department that performs chromium-free pre-treatment with the aid of an immersion series.


Chromium-free pre-treatment

While other powder coating companies have yet to start with chromium-free pre-treatment, we’ve been doing it since 2002. Our experience counts! We’ve completely mastered the quality control and process control. Of course, the switch to chromium-free pre-treatment did not occur without problems. Those who innovate must learn from their mistakes. The chromium-free pre-treatment we perform for you has a guaranteed high quality. This is also evident from our certificates!


What is chemical pre-treatment?

For powder coating, an optimal pre-treatment is the absolute basis for a quality product. In chemical pre-treatment, the substrate is conditioned appropriately using chemicals. After this treatment, the product is ready to have the powder coating applied. Every substrate (aluminium, steel and galvanised steel) receives a different pre-treatment. Chemical pre-treatment is done in three phases:

  1. Cleaning and degreasing
  2. Pickling
  3. Application of the conversion layer
    The conversion layer ensures that the powder coating adheres well and does not fall victim to corrosion.
