China Suppliers and Factory of Ground Calcium Carbonate (GCC) for Coatings and Paints - Enhance Hardness and Gloss
Product Description
Improving coating smoothness and enhances the visual appeal of high-demand surface coatings.
The addition of Useeen ground calcium carbonate can improve the surface smoothness of the coating, making it smoother and more uniform, and reducing defects such as bubbles and cracks on the coating surface. It enhances the overall appearance of the coating, making the product visually smoother and finer, and is suitable for high-demand surface coatings, such as those used in furniture and automotive surface treatments.
Improving UV resistance in coatings, preventing discoloration and ensuring long-lasting color stability for outdoor paints.
Ground calcium carbonate helps improve the UV resistance of painting, reducing the degradation caused by ultraviolet radiation. It can delay discoloration, yellowing, or cracking of the coating caused by UV light, enhancing the coating's UV resistance. This is especially suitable for outdoor coatings or paint products exposed to strong sunlight, ensuring the stability of their color and appearance after prolonged use.
