Coated calcium carbonate powder has many uses in various industries, including:

• Paints: As a filler to increase durability, hiding power, and stain resistance.
• Paper: To make paper opaque and brighter.
• Plastics: As a filler and impact modifier, and to impart strength and whiteness to PVC pipes.
• Food Additives: To increase hardness, stability, and anti-sedimentation.
• Ceramics: As a filler.
• Health Supplements: As a calcium supplement.

Coated calcium carbonate powder is also used in rubber fillers, cosmetics, medicine, construction, and environmental protection. Coating calcium carbonate with stearic acid improves dispersion and processing properties, makes it hydrophobic, reduces friction, enhances formulation stability, improves mechanical properties, and helps reduce production costs.
