Q1: How does Low O.A. Active CaCO₃ enhance coating stability?
Its surface treatment improves compatibility with resins, preventing particle agglomeration. This results in stable viscosity, reduced thickening, and excellent anti-settling performance during long-term storage.

Q2: Why is Low O.A. active CaCO₃ easier to disperse?
The treated surface reduces friction between particles, allowing them to break down quickly under shear. This leads to shorter dispersion times and more uniform distribution of fillers in the final formula.

Q3: Does it improve the final film quality?
Yes. Active CaCO₃ enhances the overall appearance by producing smoother, glossier films with fewer defects. It also improves sag resistance, which helps the coating maintain even thickness on walls and metal surfaces.

Q4: Can Low O.A. CaCO₃ help reduce viscosity problems?
Traditional ground CaCO₃ tends to raise viscosity, making mixing difficult. Active CaCO₃ helps reduce viscosity, giving formulators better rheology control. This improves brushability, roller spreading, and spray application.

Q5: Where is Low O.A. Active CaCO₃ commonly used?
It is widely used in paints, water-based coatings, solvent-based coatings, inks, adhesives, plastics, and sealants. Manufacturers prefer it when they need a combination of stability, flow performance, and enhanced final appearance.
