Thickener
Description
An efficient thickener for waterborne VOC-free acrylic copolymers, primarily to increase viscosity at high shear rates, resulting in products with Newtonian-like rheological behavior. The thickener is a typical thickener that provides viscosity at high shear rates compared to traditional waterborne thickeners, and the thickened system is more efficient in molding, paintability, edge coverage and apparent performance were improved. It has little effect on low and medium shear viscosity. After addition, the apparent viscosity and sag resistance of the system are almost unchanged.

Application Field
Architectural coatings, printing coatings, silicone defoamer, water-based industrial coatings, leather coatings, adhesives, paint coatings, metal working fluids,Other waterborne systems.
Advantage
1. High-efficiency thickener, compatible with various adhesives, easy to prepare, and good in stability.
2. Reduce costs, save energy, reduce environmental pollution, and have obvious effects on ensuring production safety.
3. It is used for roller printing and round and flat screen printing, which can make the printed products have clear outline, bright color and high color supply. The color paste is easy to prepare, has good stability, does not crust on the surface, and does not plug the net during printing.
Application method:
It can be added to abrasive slurries. Ideal results can also be obtained when post-adding in the pre-painting stage. In this case, care should be taken to check the compatibility of the coating system, due to the extremely high polymer particle surface. Therefore, it may cause coagulation or flocculation due to excessive local interaction. If this phenomenon occurs, it is recommended to dilute it with water in advance, such as diluting to a concentration of 10% before use.
The increase in high shear viscosity is a function of the amount added, the exact amount depending on the rheology required for the particular coating.
Remarks: It is better to add an appropriate amount (0.5%-1%) of ammonia water with a concentration of 20%. (This recommendation is based on product needs)
Generally, 0.2-3.0% is added to the total amount, and the color of the product is milky white.
