Improve the efficiency of your grinding process with Grind Aids, Surfactants and Dispersants

CARBOWET® GA 100, SURFYNOL® AD01, TEGO® Dispers 747 W 

Dynamic surface tension


  • Grind aid that providing optimal balance of wetting and stabilization for efficient pigment milling
  • Dynamic pigment wetting combined with low foam
  • Minimal impact on rheology and water resistance
  • Improved color rub-out and color acceptance
  • Suitable for low-VOC paints

Recommeded addition level:
Between 0.2 and 0.5 % of total formulation. Higher usage levels, up to 3 % of total formulation, are suitable for wetting and stabilization in higher PVC formulations and pigment pastes. Can be used in grind and letdown stages.

Active matter content: 85 %

Solvent: water

Architectural coatings


  • Multi-functional additive based on Gemini surfactant technology
  • Excellent dynamic pigment and substrate wetting combined with good defoaming properties
  • Reduces minimum film formation temperatures and improves film coalescence
  • Allows formulators to partially reduce co-solvent and meet VOC requirements
  • Suitable for low VOC paints and Ecolabel compliant formulations

Recommended addition level:
Between 0.1 and 1.0 % of total formulation weight. Can be used in grind and letdown stages.

Active matter content: 100 %

Solvent: none

Rub-out test

TEGO® Dispers 747 W

  • Very efficient wetting and dispersing additive for waterborne pigment concentrates and direct grinds; suitable for low-VOC and Eco-Label-compliant paints
  • Effective grinding of inorganic pigments and fillers
  • Leads to outstanding pigment concentrate acceptance with minimized rub-out values and high color strength
  • White base paint formulations show excellent storage stability at low viscosities
  • Minimized influences on coating properties

Recommended addition level:
0.3 – 1.0 % for direct grind

Active matter content: approx. 35 %

Solvent: water

Grind aid surfactants are essential for the milling process, optimizing energy usage and maximizing particle size reduction. CARBOWET® GA 100 surfactant is designed to provide dynamic surface tension control combined with good deaeration, leading to a more efficient milling process.

SURFYNOL® AD01 is a multi-functional surfactant that helps with formulating in a more efficient manner. Besides reducing dynamic surface tension and providing outstanding defoaming in pigment grind and paints, it also acts as coalescing agent.

Added to the binder, SURFYNOL® AD01 decreases the minimum film formation temperature and allows coating formulators to partially reduce the amount of co-solvent to help meet VOC requirements.
