The Universal Selection Source: Coatings Ingredients

Coatex
Thanks to its robust range of thickeners and dispersing agents, Coatex provides technical solutions to recurrent formulators issues (color acceptance, storage stability, water resistance...) for waterborne wall paint, wood coating and specialty coating formulations.

Ease of Process

Improved fillers dispersion

A good dispersion of fillers and pigments is the requisite condition to achieve good stability and for good shelf life to the finished coating system. It also contributes to the required film properties such as opacity, colour strength and gloss level if needed.

The process of dispersion of the fillers and pigments includes operation time, the use of the appropriate mechanical stirring equipment and the use of a dispersing agent.

The below graph shows the benefit of using dispersing agents to make slurries. The dispersibility is considerably facilitated allowing an increase of filler content, while achieving easily pumpable slurries (low viscosities), so it's very important to choose the right dispersing agent!

Ecodis™ and Coadis™ types dispersing agents from the Coatex range are the most recommended valuable tools facilitating the deflocculation of fillers and pigments. The choice of the right dispersing agent is also required to optimize the dispersion state.

Optimal dosage of dispersing agent is determined by carrying out preliminary deflocculation curves. The lower the viscosity, the better the dispersion state and the better the predictable storage stability.

Product recommendation per performance and formulation type:
  • High loading in fillers: Ecodis™ P 50 / P 90
  • High loading in oxide pigments and fillers: Coadis™ BR 3 / Coadis™ BR 4*
  • High loading in TiO2 + fillers: Ecodis™ P 30
  • TiO2 dispersion for Semi gloss/Gloss: Coadis™ 123 K
  • TiO2 dispersion for Gloss: Coadis™ BR 85

Ready to use

All Coatex dispersing agents, thickeners, acrylics or polyurethanes are ready to use.

Their liquid form enables easily pumpable use in addition no preparation solubilization is needed resulting in better product flow.
