4.Various Applications

 

 

 

 

Paints   and coatings

Automotive paint systems

For use in extender systems, due to gloss retention   and excellent mechanical properties. High Solids Paints: Partial substitution   of blanc fixe micro for other pigments achieves significant reduction of volatile   matters (VOC).

Pigment pastes:

Greater colour intensity and brilliance due to improved   dispersion of coloured pigments (using 10% blanc fixe micro, for example).

Powder-coating systems

It needs about 30% dosage in powder coating   production.

Paper


Increases resistance to weathering in laminates for   outdoor use.

Enhances the efficiency of extenders and fillers in   white and coloured pigmented decorative papers by expelling air in the pores.   More uniform resin penetration and reduction of mottling in coloured decorative   papers.

Plastics and rubber

Thermoplastics

Enhances the efficiency of coloured pigments in   masterbatches and pastes. Imparts a feeling of quality and luxury. Has a   positive effect on mechanical and visual properties, in particular impact   strength and gloss, in thermoplastic compounds.

Elastomers

Particularly suitable as an extender, since free of   rubber toxins. No effects on storage stability and resistance to aging.

Thermosets

For formulation of colour adjustments. Combination   with coloured pigments permits attainment of brilliant and reproducible hues   and perfect surfaces.
