Calcium Carbonate Micronized

Available from 5 to 40 Micron

A white colored stone or so called calcite rock, which is according to its low price range and high capabilities is widely used in paint, rubber, plastic, paper, P.V.C granule, cable, adhesive, artificial leather, cosmetics, health and pharmaceutical industries. Due to minimum oil absorption as well as its easy permeability in the resins, this substance is widely used in paint productions, mentioning that in brightness control and viscosity adjustment, paint could be prevented from becoming mildewed.

Calcium carbonate in Industrycalcium-carbonate-powder


Building Materials

​Building Materials covers all natural materials, artificial materials and products used in the construction and repair of buildings and structures.

ADT Co. has divided Building Materials into five groups, namely Paints, Coatings & Inks, Adhesives & Sealants, Plasters & Renders, Glass & Ceramics and Construction.



Paints, Coatings & Inks

​ADT Co. offers an extensive range of standard and specialty grades of calcium carbonate with different particle sizes and optical values. The filler selection can significantly influence the paint properties. The sheen, opacity and wet-scrub resistance can all be modified to improve the properties of the end product.


Calcium carbonate has established itself as the main extender in paints and coatings, but should be considered as a functional filler rather than an extender due to its ability to enhance paint performance. Ultrafine ground calcium carbonate types and modified calcium carbonates provide special properties in decorative coatings which allow the usage of titanium dioxide to be optimized.


Industrial coatings are primarily used for protection against potentially adverse environmental conditions. They are formulated below the critical pigment volume concentration and with lower filler content than emulsion paints. However, the selection of the appropriate filler is still of great importance because of the potential impact on sheen, viscosity and durability.


Besides its wide application in primers, calcium carbonate has become a suitable component in top coats, where high gloss and good gloss retention are demanded. Calcium carbonate is used to adjust the gloss level in other applications, such as powder coatings.


The wide variety of applications calls for fillers with a wide range of different characteristics. The natural properties of calcium carbonate, combined with ADT’s application expertise, ensure the right product for every application.


To meet the challenging demands of its customers, ADT Co. offers technical advice and a wide selection of both mineral and chemical raw materials, such as additives, binders and pigments.





Adhesives & Sealants

​Mineral fillers such as calcium carbonate and dolomite are basic raw materials in adhesive and sealant formulations. Traditionally, the main reason for using filler was cost reduction. However, functional properties are now increasing in importance as the market demands on adhesives and sealant products advance. Mineral fillers can be used to improve the mechanical properties, resistance and rheology.


The range of fillers used nowadays is almost as wide as the range of adhesives and sealants available. From white marble powder for wet-room sealants, fine and coarse powders based on calcite for tile adhesives and grouts to surface-treated fillers for moisture-sensitive systems, ADT Co. offers a wide variety of mineral fillers from a global network of local production facilities.


Specially treated carbonate grades offer an extremely low moisture content and uptake, and are thus designed specifically for reactive adhesives and sealants based on hybrid-polymer systems.






Plasters & Joint Fillers

​Plasters are used for both decorative and functional purposes. Textured plasters require mineral particles with a mean diameter of up to 7 mm and high brightness to meet the aesthetic demands of customers. In order to protect buildings from damage, the plaster should act as a water barrier yet also allow water vapor to evaporate at the same time.


Other products such as primers and fillers are used to prepare the wall surface for subsequent treatment. Operators require materials to be crack-resistant and have good sanding properties to help them work with rough surfaces.


These demanding requirements are achieved by selecting the right quantity and balance of fine and coarse mineral particles.


Natural calcium carbonate is an ideal mineral for developing products that meet these specific requirements. The nodular particle shape of natural calcium carbonate offers good workability and enhances the application properties. It also improves the hardness and mechanical properties of the films.


The available products range from powder to granules and offer different particle size distributions. The customer therefore has a wide range of options for selecting the ideal mineral fillers for any application. In addition, a variety of specialty chemicals is available through ADT Co. to provide further value for this market.





Glass & Ceramics

​Natural glass has existed since the dawn of time. It is formed when certain types of rocks melt as a result of high-temperature phenomena such as volcanic eruptions, lightning strikes or the impact of meteorites, and then cool and solidify rapidly.


Today we can subdivide the glass market into three segments:


Flat glass

Container glass (hollow glass)

Fiber glass

Calcium carbonate is used in glass as a stabilizer, and modifies the viscosity and increases the durability of the glass. For all types of glass, the common properties required of calcium carbonate are extremely low iron content, consistent chemical characteristics and low moisture content. Dolomite, a magnesium calcium carbonate mineral, can also be used as a stabilizer to improve the resistance of glass to natural or chemical attack in all three types of glass.


The ceramic market can be divided in two major segments – ceramic glass bodies and porous ceramic tiles.


Besides silica sand, calcium carbonate is another main component in the production of ceramics. Calcium carbonate is an economical source of calcium oxide, which is needed as a melting agent at high temperatures (1,050 °C), improves the mechanical and chemical strength of the glass body and reduces shrinkage from firing.







​The properties of calcium carbonate in construction have been well known for centuries. Ancient Egyptians built their pyramids from this material and the Romans later used it to erect their famous architectural structures. As a natural mineral, calcium carbonate has a multitude of characteristics that make it an ideal raw material for a wide variety of uses in concrete, asphalt, roofing, tiles and bricks. For each of these applications, there is a tailor-made product available with an optimal balance of fineness and particle size distribution for the specified purpose.


Calcium carbonate fines (5M) in the form of various Betocarb grades are used in the concrete market as high-quality fillers in concrete products such as paving stones, tubes and sewage tanks, as well as in ready-mixed and pre-cast concrete.


The workability of semi-dry, plastic or self-compacting concretes and self-leveling mortars is improved by using 5M. The particle size distribution in combination with cement and admixtures can be optimized, resulting in increased green strength, better pumping ability and less bleeding, for example. For self-compacting concretes, 5Ms have proven to be the most reliable and practical industrially produced stabilizer.


5Ms accelerate the hydration of the cement matrix, resulting in higher early strength figures. Durability is improved by better permeability. The light and stable color makes the product more aesthetic, rendering it ideal for architectural applications.


Lightweight fillers and polyethylene fibers are just two examples from the wide range of specialties that distributes for concrete applications.
