Viscosity: 1500-4500 cp (25 ℃)

application area 

Waterborne paint, latex paint, leather paint, water-based ink

Characteristics and use

It provides high shear viscosity, small thixotropy, and can obtain rheological properties similar to Newtonian body

Good flow and leveling performance

Improve the water resistance, fullness and good gloss of the film

Anti-roll coating splash, anti-microbial degradation, insensitive to PH value

It has good compatibility with most waterborne resins and additives

It does not contain any organic solvent and alkyl phenol polyoxyethylene ether (AP EO), and can be used for the preparation of environmental protection

Addition amount and use method

When single use is required, generally add 0.1-3.0% to the total amount

If it is necessary to match with other rheological additives, generally add 0.2-1.5% of the total amount

It can be used with other rheological additives to obtain the required rheological properties

Under good mixing conditions, it can be used directly

In order to make it more easily dispersed and uniform, it can be diluted with water and used

Dilution method: VOK ®- WT 204 ／ water=1 ／ 1

Storage

Keep away from heat and fire. Keep the product in a cool and ventilated place, and keep the container tight
