Hereunder a brief introduction to our fillers and Extenders for Paints, Coatings & Inks

Barites / Barytes / Barium Sulphate

Barytes or Barites is a well-known name for Barium Sulphate (BaSO4).

Natural Barytes can be characterized by high inertness in various media, high density and, as a result, low oil absorption, medium Mohs hardness of 3, easy wetting and easy to disperse. It is a good replacement for titanium dioxide and is used as a filler. It is useful in regulating the thickness of the pain. It is also very effective in increasing the stability of the paint and adding more brightness to the color of the paint. It has a clean whiteness that makes it a very efficient extender for primers. It is also useful in giving smoothness to the undercoats and chemical resistance to the walls, thereby ensuring beautiful smooth walls. It is insoluble in water. We offer high brightness (up to 98% brightness) Barytes between 300 Mesh to 500 Mesh.

Calcium Carbonate / Ground Calcium Carbonate / Calcite/ Limestone

Ground calcium carbonate (GCC) also known as marble based Calcite powder is used in a number of paint and coating applications.

Interior wall paint is the most important applications of calcium carbonates in the coatings industry. Calcium carbonate can significantly improve paint properties such as sheen, opacity (covering power) and wear resistance. Natural calcium carbonate has an alkaline pH-value and low oil absorption. This important combination of properties is ideal for primers. Calcium carbonate has become an appropriate component for top or finishing coats as well, where high gloss and gloss retention are demanded. In other applications, such as powder coatings, calcium carbonate is employed to adjust gloss level. In wood coatings it is used as a filling material to lessen cost. In automotive paint it is used as anti-stone coating and topcoat.

Calcium carbonate is a non-toxic, odorless, non-irritating white powder and one of the most versatile inorganic fillers. Calcium carbonate is neutral, which means it is insoluble in water and soluble in acid.

We offer various grades of Calcium carbonate with purity upto 99% and particle size between 100 Microns to 2 microns, we have the entire range of Calcium Carbonate.

Hydrous Clay / Kaolin / Clay

Clay is used as an extender (mostly in glossy paints) or suspending agent in oil paints, and as a pigment in water paints or in distempers. White colour, easy dispersion with anti-settling properties and chemical inertness are the main criteria for use of china clay in the paint industry.

We offer high brightness and fine particle size of China Clay for the paint industry. Our grades can be compared to that of BCK & KCG.

Calcined Clay

Calcined clays are generally used as extenders in decorative paints. Their main use is in interior matt emulsion paints, where they give a combination of high opacity, good scrub resistance and low sheen.

Calcined Kaolin, contributes to your color and performance value. It can be used in both waters based and solvent based applications as well as electrophoretic paints and inks. Calcined Kaolin has high whiteness, it provides uniform particle distribution, high dispersibility and high gloss. It is also used as a partial substitute for Titatium Di Oxide.

We offer Himafine and Himatex equivalent grades of Calcined Kaolin for the paints and coatings industry. These products have high whiteness, brightness and ultra-dispersion particle size.


Mica is used as a pigment extender that also enhances suspension, reduces chalking, prevents shrinking and shearing of the paint film, increases the resistance of the paint film to water penetration and weathering and brightens the tone of colored pigments. Mica also promotes paint adhesion in aqueous and oleo resinous formulations. There are two types of Mica and they have different applications:

  • Dry ground micronized mica: 10-20% of such mica is loaded into oil emulsion paints. The relatively larger sized jagged plates of mica align themselves in a planar fashion and serve to impart a matt finish to the coated surface.
  • Wet ground mica: Emulsions are loaded with wet ground ultra-fine smooth-surfaced plates of mica. It is also used in small-scale industrial and fire protection paints that are exposed to hazardous environment.

We offer several grades of Mica, both wet and dry ground Mica for the Paint Industry.

Quartz /Silica

Silica acts as a great low-cost extender in paints and coatings. Silica is desirable for its chemical inertness which enables for good acid, chemical, and heat resistance. Along with its chemical inertness silica’s hardness enhances abrasion resistance in paints.

High Purity Silica Powder is used in paint industry & coating for the purpose of Primers, Water based paints, Distemper, Wood Finish, Undercoat, Chemical resistance Coating, Floor Coating, Epoxy coating etc.,

We offer several grades of Quartz for the Paint Industry.


Talc is used primarily in industrial paint and coatings, wood lacquers, printing inks, fillers as well as in various coatings. Due to the characteristics of talc, it is outstandingly suitable for paints and coatings. The lamellar, hydrophobic and chemical inert structure of talc makes it to a perfect filler for the industry. 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. These properties of Talc lead to a reduction in bubble formation, corrosion and peeling.

We offer various particle sizes and brightness of Talc. We have an exhaustive range of Talc for the paints & coatings industry.


Dolomite is an important mineral filler for paint manufactures. It imparts several benefits to the paint. Dolomite is a hard mineral. Thus, it imparts scrub resistance to the paint. Moreover, it offers tremendous durability to the paint film against weathering. Dolomite has high whiteness, and thus interferes minimally with the paint color, leading to intense, opaque, accurate shades. Dolomite powder is highly dispersible and doesn’t clump together. This ensures homogeneous filler distribution in the paint which is important for uniform consistency in the paint. Dolomite has low oil absorption. 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 and manganese.

We offer good brightness, cost-effective dolomite for the use in Wall putty and paints.

Micaceous Iron Oxide, MIO

MIO (Micaceous Iron Oxide) is used in paints as a pigment extender to formulate coatings. MIO provides protection to steel because of its lamellar and flake structure. Due to its scale like formation, the steel is protected by MIO’s shiny barrier that protects against water ingress, UV light and degradation of the steel surface. The natural colour of MIO pigment is a dark, charcoal grey. Some MIO coatings also contain aluminum flakes (another lamellar pigment) that lightens its color. MIO coatings are formulated for high performance in harsh environments such as steel bridges, oil rigs and offshore environments.

Ochre (Yellow & Red)

Both red and yellow varieties of ochre are natural pigments and are characterized by their permanence of colour, opacity to ultraviolet light and their covering power. They produce high impervious paint films which resist weathering, give good protection to wooden or metal structure and can be used in either oil or water media.
