Ground Calcium Carbonate (GCC) is widely used in the paint industry as an important filler and extender. It enhances the paint’s opacity, brightness, and whiteness, improving overall coverage and finish. GCC also increases the durability and weather resistance of paints, making them more effective for both interior and exterior applications. Its fine particle size helps improve the paint’s texture and flow properties, ensuring smooth application and better adhesion to surfaces. Additionally, using GCC reduces production costs by partially replacing more expensive raw materials, making it a cost-effective and eco-friendly additive in modern paint formulations.
