Q1: Why is calcium carbonate used in paint formulations?
It improves opacity, brightness, and durability while reducing reliance on expensive pigments like titanium dioxide.

Q2: How does it enhance paint performance?
It increases paint viscosity control, improves scrub resistance, and provides a smooth, matte finish for better appearance.

Q3: Can calcium carbonate help lower paint production costs?
Yes. By partially replacing titanium dioxide, it can significantly reduce raw material expenses without sacrificing quality.

Q4: Does particle size matter in paint applications?
Absolutely. Fine-grade calcium carbonate provides better opacity and smoothness for decorative paints, while coarser grades are used in textured coatings.

Q5: Is it suitable for both indoor and outdoor paints?
Yes. High-purity, fine-particle calcium carbonate works well in interior wall paints, while weather-resistant grades are used in exterior coatings to enhance UV and moisture resistance.
