Wetting and dispersing additive stabilises inorganic and ...

The product is also well suited for co-grinds, i.e. where pigment blends are being used during the grinding phase. As the additive deflocculates and stabilises both, inorganic and organic pigments, and also provides good results with fillers and matting agents, such co-grinds now only require one wetting and dispersing additive.

PIGMENTS

Rublev Colours pigments are made directly from mineral and organic sources. Our geologist, who has many years experience selecting minerals for pigments, travels to distant locations, and hand selects mineral ores for use in our pigments. We process the minerals by pulverizing, grinding and levigating for use as fine artists' pigments.

MABS - Thermoplastic polymers, elastomers and additives

MABS can be easily molded by means of injection, extrusion or molding or using the rotation system. The high impact is more difficult because having a higher rubber content makes them more viscous. Their characteristics are similar to those of non-ferrous metals, they can be drilled, milled, turned, sawed and die cut.

How to disperse and stabilize pigments

The choice of anionic anchor group should allow for better performance with inorganic pigments and a cationic anchor group should be more appropriate for organic pigments. The surface area of the pigment also affects the level of dispersant used, and in general, if too little is used then the full benefits will not be realized.
