Optigel CG

Coatings Industry
Special Features and Benefits
Optigel CG generates thixotropic flow behavior. It improves processability and storage stability as it is highly effective at preventing solids settling. In addition, it reduces the sagging after application which makes it possible to achieve greater layer thicknesses. Optigel CG is inorganic and stable to diluted acids and bases.
Recommended Use
Optigel CG is suitable for a variety of aqueous coating systems and particularly suitable for use in highly filled architectural coatings.

Recommended Levels
0.1-3.0% additive (as supplied) based upon the total formulation, depending on the properties of the formulation to be achieved.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests. 
Incorporation and Processing Instructions
Optigel CG is hydrophilic and easy to incorporate in water. To ensure optimum distribution and the best possible effectiveness and reproducibility in applications, the additive must be added to water (20 °C ± 5 °C) slowly whilst stirring, and pre-dispersed at high shear forces for at least 20 minutes. Optigel CG should be fully hydrated before the remaining formulation components can be added to the dispersion. No wetting or dispersing additives are required to produce this dispersion. Ionic substances with potassium, calcium,
magnesium or ammonium ions or acids should be added only after the additive has been fully dispersed.

Activated phyllosilicate

Optigel CG is hygroscopic and should be transported and stored dry in the unopened original container at temperatures between 0 °C and 30 °C.
