Dispersant for titanium dioxide in automotive primer

Automotive Primer Additives: Dispersants, Anti-Settling Agents, Leveling Agents, Defoamers & Adhesion Promoters Primer is where an automotive coating system either holds or fails. It carries the adhesion to metal, the filling and hiding power, the corrosion resistance and the sandability that everything above it depends on. Yet formulators keep running into the same six problems: pigment and filler dispersion with high millbase viscosity, settling and sagging during storage and vertical application, poor substrate wetting, entrapped foam, film shrinkage, and adhesion loss on difficult substrates.
