The aqueous thickening agent is a salt of acrylic copolymers for rapid thickening aqueous free of volatile (VOC) organic compounds, primarily increased viscosity at a high shear rate, so that products with similar Newtonian fluid rheological behavior.
Thickener aqueous acid to provide the thickener is a typical viscosity at high shear rates, compared with conventional aqueous thickener, the thickening system into the model, brushing edge coverage and an apparent performance are promoted. For low, medium shear viscosity has little effect, after the addition, and the apparent viscosity sag resistance of the system almost unchanged. Unlike generation thickeners, surface can produce a strong bond with the Examples of the polymer binder, even under high shear forces, such as a brush or roller in the application process, which does not interact damaged, and therefore, low shear rate viscosity of the coating with little effect on shear rate viscosity.

Scenario:
The aqueous salt widely used thickeners can be used in the paint industry e.g., aqueous acid, waterproof coatings, waterborne coatings, printing coatings, architectural coatings, interior and exterior paints, paint, leather side of the oil, ink and the like various interior and exterior paint formulations , especially suitable as a synergistic thickening over the balance, providing high shear viscosity using a coating formulation together with the light from matt to high and low shear viscosity is reached. The aqueous acid thickener is a low viscosity liquid, it is easy compatibility, help improve the coating production process.
