20 Microns says approvals of up to 10 years lock in supply

20 Microns Limited says a new customer grade typically takes three to 10 years to move from an initial brief to commercial supply. Once a grade is specified in a formulation, changing supplier requires requalification, supporting repeat orders; paints and coatings, its largest FY26 segment at 46% of revenue, includes relationships of up to 25 years.

How do 20 Microns approvals create long-term supply relationships?

20 Microns says its approval process typically takes three to 10 years, starting with a customer brief that defines a target property or cost in a formulation. The company then designs a grade by selecting the mineral, processing route and surface treatment, followed by repeated trials in the customer’s plant and products before commercial approval.

20 Microns says approved grades are incorporated into customer formulations and reordered for years. A supplier change can require the customer to requalify its own product, creating what the company describes as high switching costs. This is a qualification-based retention mechanism, rather than evidence that every customer is contractually committed to a single supplier.

One disclosed example shows the potential duration of the process: a leading fast-moving consumer goods company is moving into commercial supply after nearly 10 years of trials with 20 Microns. The company also states that approval periods vary by customer, sector and application, so the three-to-10-year range is a typical timeframe rather than a uniform schedule.

The model depends on application-specific performance rather than selling standard mineral volume alone. 20 Microns says it supplies more than 100 engineered grades customised to customer formulations, compared with a typical commodity producer selling a few standard grades by tonne. Its stated end-product outcomes include opacity, strength, flow, gloss control and lower formulation cost.

Which 20 Microns end markets have the longest relationships?

20 Microns reports its longest disclosed relationships in paints and coatings, which accounted for 46% of FY26 revenue and included relationships of up to 25 years. Customers listed in that segment include Asian Paints, Berger, Kansai Nerolac, AkzoNobel, Nippon Paint, JSW Paints, Indigo, Jotun, Shalimar and Birla Opus.

Polymers, pipes and cables was the second-largest end market at 26% of FY26 revenue, 20 percentage points below paints and coatings. 20 Microns cites 10-year relationships with Polycab, Supreme and Finolex in this category. Rubber represented 10%, while paper, ceramics and other applications represented 5%, 4% and 9%, respectively; each is described as having relationships of more than 10 years.

The 25-year figure does not apply to every paints customer. 20 Microns says Birla Opus has been a customer for three years since its launch, showing that the 46% revenue segment contains both newly developed and long-established accounts. The company’s stated objective is to grow alongside customers after a grade becomes specified in their formulation.

What makes 20 Microns grades specific to customer formulations?

20 Microns uses mechanical, thermal and chemical processing to tailor mineral grades to applications in paint, polymer and rubber. Mechanical work includes micronising, sub-micron grinding and classification to control particle size and shape; thermal processing includes calcination to alter structure, brightness and hardness; chemical processing can reduce impurities or coat particle surfaces for compatibility.

These processes can change particle-size distribution, brightness, whiteness, purity, surface chemistry, oil absorption and dispersion, according to 20 Microns. The company links those characteristics to opacity and finish in coatings, strength and stiffness in polymers, processing speed and flow, and gloss control. It says the processes are deployed individually or in combination depending on the grade and application.

20 Microns divides its portfolio into three tiers. Tier 1 industrial minerals, including ground calcium carbonate, kaolin, talc, barytes, silica, mica and feldspar, form its core volume base. Tier 2 includes performance and specialty minerals such as sub-micron calcium carbonate and high-aspect-ratio talc, while Tier 3 functional additives and nano products are described by the company as its fastest-growing and highest-value-added category.

The company reports a research and development team of more than 35 scientists and engineers, a Department of Scientific and Industrial Research-recognised research centre in Vadodara, and four breakthrough innovations commercialised in FY26. Those innovations included Talc HFM 25 SD for plastic films, White Kaolin for cosmetics, Hypertherm UT for greenhouse films and Hydroxylgel A1 for coatings and construction.

How do functional additives deepen 20 Microns customer relationships?

20 Microns says functional additives generate 25% of revenue from more than 250 specialised grades and more than 100 customers. Fillers account for the remaining 75% of revenue, with more than 150 grades and more than 800 customers. The comparison shows that functional additives have a larger disclosed grade count despite serving a smaller customer base.

The company attributes this mix to formulation-specific development. Its functional additive range includes white pigment opacifiers, matting agents, anti-blocking additives, rheological additives, flame retardants, rubber activators, micronised waxes and calcium oxide desiccants. 20 Microns says these products are priced on the performance delivered rather than solely on tonnes supplied.

Specific functions illustrate the application role. White pigment opacifiers can partly replace titanium dioxide in paints and coatings; anti-blocking additives prevent polymer-film layers from sticking; and rheological additives control flow, viscosity and settling in paints, inks and adhesives. Rubber activators are intended to speed and improve vulcanisation in tyres and other rubber goods.

In 2026, 20 Microns showcased nano-particle inorganic additives for paint films at PaintIndia, anti-blocking agents and performance minerals at PlastIndia, and products including Zinkomer, Supermag, K STOFF, Akfleef and Delam barrier clay at India Rubber Expo. These events relate to the company’s stated focus on functional additives, customer-specific grades and applications beyond conventional fillers.

Conclusion

20 Microns presents its customer retention model as the result of lengthy technical qualification and formulation specification. The three-to-10-year approval process, the need to requalify products when suppliers change, and relationships of up to 25 years in its 46% paints and coatings segment provide the company’s evidence for recurring supply demand. Functional additives extend that model through more than 250 specialised grades serving more than 100 customers.

What to watch next is execution of the growth levers disclosed for FY2030: a Rs 100 crore capacity expansion, applications beyond paints and research-led launches. 20 Microns is also developing nano-minerals, electric-vehicle fillers and battery-related applications, while the outcome of its submitted bid under India’s rare-earth permanent-magnet scheme remains awaited.
