Vertal

Vertal® Your cost-effective solution for interior and exterior latex paints

  • Reduced formulation costs
  • Improved opacity and stain blocking
  • Film reinforcement

Vertal® products are highly lamellar (platy), multi-functional, cost-effective mineral pigments that improve the performance and reduce the formulated costs of interior and exterior latex paints and primers.

Using Vertal® products offers coating formulators the following performance advantages:

  • Opacity and stain hiding
    Vertal® mineral pigments improve TiO2 distribution in the bulk paint film and across the %PVC spectrum.  This keeps formulated costs at a minimum while optimizing the effectiveness of expensive prime pigmentation.
  • Barrier properties and stain-blocking
     The unique, lamellar morphology of Vertal® talcs provide improved barrier properties for interior and exterior waterborne primer/sealer applications. They increase coating hydrophobicity, reduce permeability, and reduce bleed-through of stains and salts that can cause further discoloration failures of topcoats and enamels.
  • Film reinforcement
    Vertal® platy talcs provide improved film reinforcement and dimensional stability to coatings for additional protection against grain-cracking and mud cracking.
  • Ease-of-dispersion 
    Vertal® mineral pigments are low binder-demand talc products that disperse readily in waterborne systems with a minimum viscosity build.
