Talc Mineral And Its Usage In The Paints & Coatings Industry

Minerals, both natural and synthetic, play an important role in regulating the efficiency of paints and coatings. They contribute to the colour, durability, protective features, texture, gloss, and application properties of the paints and coatings. Paint manufacturing requires various raw materials such as mineral additives, binders, surfactants, polymers and solvents. The extenders or fillers used in the manufacturing of paints amplify its properties such as opacity, hardness and UV stability. The mineral additives used in this industry are calcite, talc, titanium dioxide, quartz, feldspar, mica and clay to mention a few.

But which of these minerals is the best to be used in the paints and coating industries?

The main criteria to select a mineral solution for paint manufacturing is high opacity and low cost.

For example, titanium dioxide offers high opacity but is an expensive mineral and that makes it an inefficient choice of mineral for the commercial paints and coatings industry.

Calcite works as a brilliant substitute for titanium dioxide, as it is less expensive and has more or less similar properties. However, talc mineral can massively optimize paint manufacturing and enhance its properties. 

Do you know what Talc mineral is?

Talc is an amazingly variable mineral with a massive range of uses across several industries. It is the softest rock on the planet. Softness, water repellency, chemical inertness, platyness, and an affinity for organic compounds are all characteristics of talc. It has low electrical and thermal conductivity. It can resist heat up to 1300 degrees celsius and it is non-explosive and non-flammable.

These properties make talc a highly desired multi-functional filler and process facilitator in several industries such as plastics, paper, ceramics, and paint to mention a few. Usage of talc mineral has optimized paints and coatings manufacturing immensely.

We have listed a few of the benefits of using Talc mineral in the Paints and coatings industry below:

1. The size of the talc mineral enhances and affects the physical properties such as impact resistance, scrub resistance, and adhesive behavior of paints.
2. The stabilization in the paints and coatings industry achieved using talc mineral is much better than titanium dioxide.
3. Talc creates a physical barrier when used as an additive in coatings and prevents the core areas of the film from oxidizing.
4. It usually gives a subtle satin finish thus decreasing the glossy finish of the paint.
5. Talc minerals with high purity give high opacity without having no adverse effect on the viscosity, density, and hardness of the paints.
6. It can enhance the stability in paints and coatings using talc mineral as a primer.
7. Talc and chalk can be used as a filler or extender of expensive pigments in solvent and aqueous paint applications. Talc is used in surface coatings because of its off-white colour.

The manufacturers must consider certain factors such as the purity of talc mineral, whiteness, size of the particle, oil-absorbing properties and matting effect while selecting Talc mineral solutions for the paints and coating industry. 

Aryan Tiles is one of the biggest producers and suppliers of talc minerals in India. We extract our talc mineral from several regions of Rajasthan. Our scientists and process experts collaborate with customers to develop innovative minerals that satisfy their specific industries’ needs.
