Talc

Talc in paint and Coating is not used as a filler (to increase the volume) but as a functional component that introduces a number of properties. The surface of pure Talc is hydrophobic, and the particle form is laminar. Different Talc grades have a more or less pronounced laminar structure (macro or microcrystalline) and can contain other minerals. Talc in industrial Coatings has many benefits, which include corrosion protection, solvent reduction and adhesion. Talc is used in paint to improve its physical properties, which include wet scrub resistance, optical properties, weathering protection and more. Read more . . .

Other Usages of Talc:

Talc basically has five characteristics that make it a valuable mineral for industrial and domestic applications.

• Softness
• Chemical inertness
• Lamellarity
• Whiteness
• Affinity for Organic Chemicals

In fact, Talc is found in everything from animal feed to tires, and has been for millennia. As long as 15,000 years ago, cave dwellers used Talc in their paints. For at least 5,000 years, it has been used in cosmetics, especially as a skin lightener, and 1,000 years ago, the Chinese began using it in their glazed pottery. Listed below are several of Talc’s uses for the industries of the world:

• Paper Industry: Talc's number one consumer is the Paper Industry. It is used as filler and Coating for paper products. Furthermore, Talc helps control the paper's pitch while the paper is being processed. It improves paper smoothness, water retention in certain papers, and printability and runnability for coated papers.
• Ceramics Industry: The Ceramics Industry is another Talc consumer. The glazing and bodies of the ceramics rely on Talc to give ceramics their gloss, whiteness and shape. Dinnerware, Sanitary ware, tiles, porcelain, and electrical insulation are all part of ceramics made with Talc. It is also used as a flux and to control thermal expansion - particularly in catalysts and particulate filters. Read more . . .

Red & Yellow Iron Oxide

Natural Iron Oxides are derived from Hematite, which is a Red Iron Oxide mineral; Limonites, which vary from yellow to brown, such as ochers, siennas, and umbers; and Magnetite, which is black Iron Oxide. Synthetic Iron Oxide Pigments are produced from basic chemicals. The three major methods for the manufacture of synthetic Iron Oxides are thermal decomposition of iron salts or iron compounds, precipitation of iron salts usually accompanied by oxidation, and reduction of organic compounds by iron. Synthetic Iron Oxides have become increasingly important due to their pure hue, consistent properties, and tinting strength. Single-component forms are mainly produced with red, yellow, orange and black colours. Read more . . .

Red & Yellow Iron Oxide Usages:

• The building materials industry is the biggest user of Iron Oxide Pigments. Uses include colouring concrete and mortar because of their good dispersibility and good tinting strength. They are extensively used in the manufacture of Paving Blocks, Chequered Tiles, Stamped Concrete and etc.
• Paints industry is the second largest user of Iron Oxide Pigments. Most paint applications require use if micronized and dispersible grades of Pigments to get optimum colouring effects and maintain paint film strength.
• Pigments used in Plastics need high purity, tinting strength, high heat resistance and good dispersibility. Read more . . .

Calcium Carbonate

Calcium Carbonate is an exceptional mineral. The chemical formula CaCO3 covers a raw material, which is widespread throughout nature, whether dissolved in rivers and oceans, in molten form as “cold” carbonatite-lava, or solid as a mineral in the form of stalactites, stalagmites or as the major constituent of whole mountain ranges. Plants and animals need calcium carbonate to form their skeletons and shells. In fact, when considering our lives, modern mankind could hardly imagine existing without calcium carbonate. Almost every product in our daily lives either contains calcium carbonate or has some association with the mineral during its production. Read more . . .

Calcium Carbonate Usages:

• Coatings: In paints and Coatings, calcium carbonate has established itself as the main extender. Fineness and particle-size distribution can contribute to the opacity of Coatings. Moreover, calcium carbonate can offer improvements in weather resistance, anti-corrosion and rheological properties, coupled with low abrasiveness, low electrolyte content, and a pH stabilising effect. In water-based systems calcium carbonate reduces the drying time.
• Paper: Over the last 30 years, the use of calcium carbonate has grown significantly as technology in the paper industry has moved from acid to neutral sizing.
• Plastics: Calcium carbonate is by far the most important mineral for compounding with polymers. By weight it accounts for more than 60% of the filler and reinforcements market. Read more . . .
