As shown in the graph above, compared to other competitors, the extremely high level of gloss required for alkyd emulsion based formulations is achieved by using COADIS™ BR 85!
The offered solutions of COATEX provide also a gloss level similar to that of solvent-borne paints!

Figure 2: Viscosity evolution after 1 week at 50° C
Alkyd Emulsion paints formulated with a combination of COADIS™ BR 85 and COAPUR™ XS 22 are more stable. In fact, viscosity drop is drastically limited and application properties are not damaged (Sag and leveling compromise is improved)

Compared to other competitive dispersing agents, superior in-can stability is achieved!
Thanks to its reduced ionic character, COADIS™ BR 85 allows a better dispersion and stabilization of various TiO2 grades for high gloss paints and calcium carbonates of finest grades as well.
