Water-based coatings, water-based inks, petroleum drilling, daily chemicals, building materials, etc.
1. With good thickening property in aqueous system;
2. With the rheological characteristics of shear dilution and rapid viscosity recovery after shear stop.
3. Exhibit excellent acid and alkali resistance, with thickening efficiency remaining stable across the pH range of 2 to 12, and demonstrates good thermal stability.
4.When coexisting with high-concentration electrolytes (e.g., NaCl, CaCl), prevent viscosity reduction or precipitation caused by salting-out.
