MM31® is an innovative chemical pretreatment from AD Chemicals. The product combines the worlds of mechanical and chemical pretreatment. In the field of pre-treatment methods, mechanical pretreatment (such as blasting or sanding) followed by a coating system is common practice. What would be the result if a mechanical pre-treatment could be combined with the added value of a chemical pretreatment?

By applying MM31® directly after a mechanical pretreatment, the two worlds come together. This results in a clean, ready to coat surface and a quality improvement of the coated substrate on both corrosion protection and paint adhesion properties. This is the result of forming of a conversion layer. The product also offers protection against flash rust and undercreep corrosion, allowing an extended storage time of up to 48 hours.
Conversion layer, chromium-3 basis
MM31® creates a chromium-3 based protective conversion layer, which is formed on the metal by a chemical reaction with MM31®, whereby the metal itself contributes to the formation of the layer. This layer provides a more uniform metal surface.
Application procedure
Flexible application
MM31® can be applied flexibly in manual and automated metal pretreatment processes, enabling easy integration into surface preparation and coating workflows across a wide range of metal treatment applications.
Benefits of MM31®
- The conversion layer applied with MM31® improves adhesion of powdercoating or wet paint and increases the corrosion protection properties.
- Flash rust resistance on steel products, white rust protection on zinc, improved bare metal corrosion resistance on aluminum.
- Allows an extended storage time prior to coating up to 48 hours.
- Full chemical pretreatment applied in one process step. MM31® replaces therefore a pretreatment line with a simple process without the need for heated baths and the use of heavy chemicals.
- Results are similar or better than the requirements of international quality standards such as FROSIO, NACE, GSB, QUALICOAT and QUALISTEELCOAT.
- Replace solvents in the business process with a user-friendly and non-aggressive chemical. Protect employees against exposure to harmful substances.

This video explains the MM31® technology and advantages.
Demonstration video
This demonstration video shows the ease of applying MM31® in various pre-treatment processes in practice and gives insight in test results such as salt spray tests.
MM31® in practice at BMS Coating
A reliable coating process starts with a properly pretreated surface. At BMS Coating, MM31® is used as a chemical alternative to the mechanical pretreatment of aluminium components.
Following cleaning with Cleaner OV, MM31® prepares the surface for powder coating. This approach reduces the need for additional process steps and helps BMS Coating move components through the process more quickly.
In this video, Barry, owner of BMS Coating, explains why the company chose MM31®. You will see the complete process, from untreated aluminium and chemical pretreatment to the final powder coated result.
