QK4200 is a liquid rheological additive, which is suitable for water solubility, dispersion and emulsion system additives to produce high tensile fluidity, and improve the resistance of fluid hanging and sedimentation resistance. This additive can also be added later, can be applied to water, water and alcohol ether, alcohol solvent mixture system.

Storage and transportation
Temperature-sensitive, storage under dry conditions. A slight turbidity may occur during storage, but it does not affect the rheological effect.
Storage time is not recommended to exceed 12 months.
Special attention
If it is used in conjunction with a desiccant, it may produce discoloration, which may be due to the formation of metal complexes. The rheological effectiveness in this case should be evaluated. Under the standard measurement, he had no negative effect on the yellowing. Yellow lows and higher additive dosage should be evaluated in suspected systems.
Application message
Industrial paint
Features and advantages:
After stirring is added to the coating system, the additives will produce a three-dimensional network structure, forming the dynamic flow behavior is very suitable to prevent settlement and antifluid hang performance without affecting the flow level.
Recommended dosage
The dosage of 0.2% -1% is based on the total formulation to prevent settlement.
The aid dosage of 0.5% -2% is based on the total formulation to prevent bleeding, but this depends on the overall solid content of the formulation.
The above data are the empirical amount, and the optimal amount should be determined by a series of tests.
Add method guidance
The added additives shall be added to the coating system under moderate shear force to ensure uniform mixing and rapid dispersion. It does not need a special temperature control, the additive can be added to the abrasive stage, and is also suitable for later addition to adjust the viscosity. If the additive is suitable for this system, the rheological effect will be significantly increased. It depends on the time and polarity, and generally the rheological effect can be evaluated at 2-24 hours after mixing.
