Claytone® VZ

Coatings Industry
Special Features and Benefits
Due to its special organic modification, CLAYTONE-VZ is ideally suited to influencing the flow behavior of polar to medium-polarity coating systems. Using the additive produces thixotropic flow behavior, and therefore results in significant improvement to the anti-sagging properties while at the same time maintaining good leveling. This also optimizes storage stability, and prevents pigments and fillers from settling.

Recommended Levels
0.3-2% additive (as supplied) based on the total formulation.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
The additive is incorporated while stirring, and is preferably dispersed in the mill base at high shear forces for at least 10 minutes. Alternatively, it can also be incorporated using a 10 % pregel. The effect of CLAYTONE-VZ can be increased by adding a booster or small quantities of a polar solvent or water.

Special Features and Benefits
Claytone® VZ is a modified phyllosilicate rheology additive in powder form. In unsaturated polyester based putty compounds Claytone® VZ develops a strong thixotropy that provides a smooth application behavior. The additive improves in particular the resin separation on top of the putty surface during storage. Compared with commonly used thixotropes, a lower dosage can be applied.

Recommended Levels
0.2-2% additive (as supplied) based on the total formulation.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
Claytone® VZ can be incorporated directly into the resin, and should be dispersed together with the fillers at a high shear force.

Organophilic phyllosilicate

Claytone® VZ should be transported and stored dry in the unopened original container at temperatures between 0 °C and 30 °C.
