The following modules are available:

Standard module:

These 12 colourants are selected on the basis of the widest possible colour range while minimizing the total amount of colourants. In this way there are enough options open for fine-tuning the total selection, even in the smallest machines with 16 canisterss

Frequently asked questions

Yes, the UNI Plus series are VOC free, wich means that they are completely free of volatile organic compounds. Besides it has the advantage that you can tint both water- and solvent decorative based paints. Even if your solvent based paints are only a limited part of your total volume, it is a nice benefit that also these paints can be supplied in the wide colour range with only a limited stock of base paints. 

IND Pro is also VOC free and has been specifically designed as a universal colorant for many different chemistries commonly used for the heavy duty Industrial and Protective Coatings segments, normally solvent based or high solid.

Yes, in practice we have learned that the UNI Plus series can also be used for the waterborne industrial coating market, for 1k and 2k coatings applied on concrete and steel with a mainly decorative-aesthetic purpose.

No, for the specific group of Heavy duty Industrial Protective Coatings, often solvent based or high solid, identified as “2 component Poly-Urethane (PU)” or ”2 component Epoxy (EP)”, the IND Pro series is the best choice.

The main differentiator is the very high compatibility with both water- and solvent based paints, in many different paints and coating types. This results in additional benefits, such as improved opacity, more colour stability and a wider final colour range that can be made. UNI Plus has a higher colour strength in general compared to existing universal systems, resulting in lower cost.

Performance in water based systems is similar, in Alkyd solvent based paints some types will perform better with the ALK system. With UNI Plus there is more choice for different modules.
