Paints & Coating
Our grounding calcium carbonate is used as a filler in the paints industry due to its competitive pricing, chemical and physical properties such as whiteness, low oil absorption and enhancement for opacity. Ground calcium carbonate is used as a booster for adhesives and sealants profile.
Adhesives
Calcium carbonate is a relatively soft, insoluble mineral that is widely used to reduce cost and to control shrinkage in adhesive and sealant formulations.
Powder coating
calcium carbonate products can improve the physical and rheological properties of powder coating.
Joint sealant
calcium carbonates increase the resistance and durability of adhesive & sealant joints, and thus the life cycle of the final products.
Paper
Calcium carbonate is commonly used in conjunction with kaolin in papermaking: it can increase the luster, whiteness, opacity, and ink absorption of paper. The shift from acidic to neutral sizing methods in the papermaking industry has greatly increased demand for calcium carbonate. Calcium carbonate is chiefly used as a surface coating in the neutral papermaking process, and is also used as a filler to cut expenses.
Inks
Calcium carbonate activated with a compound coupling agent is used in ink, and can effectively cut costs, increase volume, prevent settling, and improve the ink's luster, transparency, adhesion, and color brightness.
