FAQ

GCC 1250 mesh is ground natural limestone with irregular particle morphology (D50 ~2 µm), lower cost, and higher hardness. PCC has controlled crystal morphology (rhombohedral or scalenohedral), narrower PSD, and higher surface area, making it preferred for high-gloss paint. GCC is the cost-effective choice for flat/semi-gloss formulations.
