Optigel LX

Coatings Industry
Special Features and Benefits
Optigel LX 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 tendency after application which makes it possible to achieve greater layer thicknesses.Optigel LX is a mineral with a protective colloid and is stable to diluted acids and bases.
Recommended Use
Optigel LX is suitable for a variety of aqueous coating systems and particularly suitable for use in architectural coatings.

Recommended Levels
0.5-1.2% additive (as supplied) based upon the total formulation, depending on the properties of theformulation 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 LX 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 LX 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. Optigel LX can be also be added to the formulation directly, as a powder at the start of manufacture.
Special Note
Optigel LX reacts sensitively to ions. If the mains water being used has a high total hardness, use deionized water for processing.

Activated phyllosilicate

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