Calcium Carbonate for Paints :
Calcium carbonate powder is used as a dilution, an agent to either reduce or enhance gloss. Charbhuja Minerals is one of the leading manufacturers and suppliers of a wide range of Calcium Carbonate powder for Paints and other industries.
The fine calcium carbonate powder is used even more extensively in the aqueous paint industry. It can prevent the pigment from settling, promote good dispersion, and improve luster. The performance intensifying qualities have ensured the large-scale acceptance of calcium carbonate in the paint industry. Calcium carbonate is the pigment that extends in ink, providing turbidity, viscosity, and ball control. They can also be used as dyes and dispersion acids. Calcium carbonate powder is also used in the paint industry as an extender/ spreader for increasing opacity. Not only in the paint industry but calcium carbonate is also used as a filler and extender in many other different industries. Our range of calcium carbonate powder is of high quality and can be used in a different number of other applications. The calcium carbonate powder is an anti-settling agent and also an opacifying agent which enhances the gloss and stability characteristics of the paint.
Magnesium Carbonate (Dolomite) for Paints :
Dolomite is an important mineral filler for paint manufacture. Dolomite has high whiteness, and thus interferes minimally with the paint color, leading to intense, opaque, accurate shades. Dolomite is a cost effective filler providing substantial cost benefits compared to other fillers For application in paint, dolomite must be very pure and in particular devoid of the color imparting impurities such as oxides of iron, chromium, manganese etc. Dolomite is a hard mineral. Dolomite has high whiteness, and thus interferes minimally with the paint color, leading to intense, opaque, accurate shades. Dolomite is magnesium calcium carbonate, which is generally used in paint as a filler. Dolomite is a hard mineral, thus it imparts very good scrub resistance to the paint.
Magnesium Silicate (Talc) for Paints :
Talc pigments are used in a great variety of industrial paints, especially in primers and undercoats. Structural steel primers are fibrous talc as all or part of the extender. It improves selling properties, film strength and recoatability. Talc is used primarily in industrial paint and coatings, wood lacquers, printing inks, fillers as well as in various coatings. … Talc increases coverage and weather resistance of the products. The use of talc creates a barrier effect, which limits the penetration of water and corrosive agents into paints and coatings.
