From production line to workshop: MM31® sets new standard in one-step pre-treatment

how can the quality of corrosion protection and paint adhesion be further improved, while at the same time making processes simpler, safer and more sustainable?

With the introduction of MM31®, AD Chemicals has set an important step in this trajectory. MM31® combines cleaning, degreasing, corrosion protection and paint adhesion in a single process step.

In the field of pre-treatment methods, mechanical pre-treatment (such as blasting or sanding) followed by a coating system is common. What if mechanical pre-treatment could be combined with the added value of chemical pre-treatment? This was the starting point for the development of MM31®.

In a regular chemical pre-treatment, the generic process consists of degreasing, etching and applying a conversion coating. After mechanical pre-treatment the surface is only roughened (compared to the etching step), no added value is created to the metal because there is no conversion coating, as is the case with chemical pre-treatment.

Product use MM31®
By applying MM31® after mechanical pre-treatment the two worlds come together. This results in a clean, coating-ready surface and an improvement in the quality of the coated substrate. The result: a surface with improved adhesion properties and long-lasting corrosion protection.

Another advantage is that metal treated with MM31® that has not yet been coated also acquires so-called passivation properties. In other words, this means: flash rust protection on steel products, white rust protection on zinc, improved bare metal corrosion resistance on aluminium. This allows for extended intermediate storage, enabling companies to further optimise coating processes where needed.

The strength of MM31® lies in its ease of application. It can be integrated in practically every standard business process. Whether applied manually with a cloth, using a low-pressure pump or spray, or fully automatically in a spray booth, a single step is all it takes. A new addition is the introduction of the spray can, making the technology directly available for repairs, maintenance, and small-scale applications.
