FAQS
Ground calcium carbonate (GCC) is produced by mechanically grinding natural limestone, chalk or marble. Precipitated calcium carbonate (PCC), on the other hand, is manufactured through a chemical process, leading to a purer, more consistent product with controlled particle size and shape. PCC typically offers superior optical properties and reactivity compared to GCC, making it suitable for applications demanding high performance, like specialized coatings and plastics. Choosing between the two depends on the specific application requirements and cost considerations.
Particle size is critical in paint. Finer particles enhance opacity, gloss, and color development, leading to a smoother finish. Larger particles contribute to scrub resistance and durability. The optimal particle size distribution depends on the specific type of paint—architectural, industrial, or automotive. Careful control of particle size during production ensures optimal paint performance and desired aesthetic properties.
Calcium carbonate itself is a naturally occurring, non-toxic material. However, its environmental impact depends on the sourcing and production methods. Utilizing recycled calcium carbonate or by-products from other industrial processes significantly reduces its carbon footprint.
