WT-121-Product manual

WT-121 Waterborne Polyamide Wax Rheology Additives are prepared by pre-dispersing and activating a specially modified polyamide wax in deionized water and a co-solvent to form a thixotropic paste. It is specially designed for use in waterborne coating systems, effectively establishing thixotropic viscosity in the system, controlling sagging and anti-settling.

Features

Compared with traditional aqueous rheological additives, it has the following advantages:

1. Excellent thixotropy, sag resistance and anti-settling properties.

2. In the waterborne metallic paint, the positioning of the aluminum powder can be strengthened, and the gloss of the paint film can be increased.

3. Can be used in high polarity systems that are compatible with water.

4. It is easy to disperse and can be dispersed in a high-speed disperser without grinding.

5. Good water resistance.
