Dolomite Powder in Paints


Dolomite is a type of limestone which is highly rich in magnesium and calcium carbonate. It also has smaller amounts of several other minerals. It is an important mineral filler in the paint industry. As it is a hard material, it imparts scrub resistance to the paints. Moreover, it also offers high durability to paint film against weathering. 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 colour imparting impurities such as oxides of iron, chromium, manganese, etc. Golden Exports offers the best quality dolomite powder in India for the paint industry. Its whiteness is extremely high and it has a low oil absorption making it one of the most preferential minerals.



Dolomite in Glass Industry


Dolomite Powder is one of the carbonate minerals composed of calcium magnesium carbonate. It is white in colour and is mainly used as filler in soaps, detergents, paints and ceramics. This powder is well known in the market for its ease of dispersion, high purity and accurate composition. Dolomite is a very useful mineral in the glass industry since CaO and MgO perform the role of network modifiers in the glass manufacturing process. Golden Exports is the leading dolomite powder Exporters & Suppliers in India. They interfere with the network of the glass-forming oxides like SiO2. Since the network gets disturbed, the melting point and viscosity of the glass-forming oxide decreases. Further, depending upon the concentration and composition of network modifiers, one can alter glass transition temperature, density, rigidity, durability and dimension stability. Golden Exports is one of the renowned Exporters and suppliers of a wide range of dolomite powder in India.
