20 Microns Limited says approval cycles underpin repeat supply

20 Microns Limited says a new mineral grade typically takes three to 10 years to progress from a customer brief to commercial supply. The company says approved grades become part of customer formulations, making replacement subject to requalification; it reports customer relationships of up to 25 years in paints and coatings and more than 1,000 business-to-business customers.

How does 20 Microns turn a grade into repeat supply?

20 Microns turns a grade into repeat supply through customer briefing, grade design, trials and approval, followed by repeat orders. A customer first identifies a target property or cost in its formulation, after which 20 Microns selects the mineral, processing route and surface treatment for the required application.

The company says repeated trials take place in the customer’s plant and products before commercial approval. This process typically takes three to 10 years from the initial brief to commercial supply, although the period varies by customer, sector and application. Once approved, the company says the grade is locked into the formulation and reordered for years.

One disclosed example involves a leading fast-moving consumer goods company that is moving into commercial supply after nearly 10 years of trials with 20 Microns. This example illustrates the gap between product development and revenue generation in the company’s qualification process.

The development process can combine mechanical, thermal and chemical methods. Mechanical processing includes micronising, sub-micron grinding and classification; thermal treatment includes calcination; and chemical processing can reduce impurities or coat particles to improve compatibility with a polymer, paint or rubber formulation.

Which customer markets have the longest 20 Microns relationships?

Paints and coatings is 20 Microns’ largest disclosed end market at 46% of FY26 revenue, and the company reports relationships of up to 25 years in that sector. Its listed paint and coating customers include Asian Paints, Berger, Kansai Nerolac, AkzoNobel, Nippon Paint, JSW Paints, Indigo, Jotun, Shalimar and Birla Opus.

Polymers, pipes and cables is the second-largest market at 26% of FY26 revenue, 20 percentage points below paints and coatings. Listed customers include Supreme, Astral, Finolex, Ashirvad, Polycab, Reliance, LyondellBasell and Ampacet, while the company identifies 10-year relationships with Polycab, Supreme and Finolex.

Rubber accounts for 10% of FY26 revenue, while paper, ceramics and other markets account for 5%, 4% and 9%, respectively. The other category includes adhesives, inks, personal care, oil and gas, with named customers including Pidilite, Henkel, Micro Inks, IMCD, Unilever, Dabur, ITC, Oil and Natural Gas Corporation and Schlumberger.

Why are 20 Microns grades difficult to replace?

20 Microns says its grades are difficult to replace because changing supplier requires a customer to requalify its finished product. The company identifies this requalification requirement as a high switching cost after the original three-to-10-year route from brief to commercial supply.

The company supplies more than 100 engineered grades customised to customer formulations, compared with the few standard grades it associates with a typical commodity producer. Its mineral feedstocks include calcium carbonate, kaolin, talc, barytes, silica, mica and feldspar, which can be engineered for particle size, brightness, purity, surface chemistry, oil absorption and dispersion.

These characteristics affect specific customer outcomes, including opacity and finish, strength and stiffness, flow and processing speed, gloss control and formulation cost. For example, a chemical coating can help a particle bond with a customer’s polymer, paint or rubber system, while calcination can alter mineral structure, brightness and hardness.

20 Microns also contrasts formulation approval with an ordinary transaction based on tonnes. It states that the customer relationship is based on a grade being approved into a formulation, so switching requires the alternative material to undergo the customer’s testing and approval process.

How do functional additives deepen 20 Microns customer relationships?

20 Microns says functional additives deepen customer relationships because each product is tailored to a customer formulation and designed to deliver a defined function. Functional additives account for 25% of revenue from more than 250 specialised grades sold to more than 100 customers.

Fillers account for the remaining 75% of revenue, with more than 150 grades supplied to more than 800 customers. Functional additives therefore have about two-thirds more grades than fillers while serving about one-eighth as many customers, according to the company’s disclosed counts.

The functional range includes white pigment opacifiers for hiding power, matting agents for gloss control, anti-blocking additives for polymer films, rheological additives for flow and viscosity, flame retardants, rubber activators and calcium oxide desiccants for plastics and masterbatch. The company says these products are priced on performance delivered rather than per tonne.

20 Microns places functional additives and nano products in Tier 03, which it describes as its fastest-growing and highest-value-added portfolio tier, as well as the focus of research and development and capital expenditure. Tier 02 performance and specialty minerals, including sub-micron calcium carbonate and high-aspect-ratio talc, have margins above the company average, according to management, while Tier 01 industrial minerals remain the core volume base.

What supports 20 Microns customer-specific development work?

20 Microns supports product development with more than 35 scientists and engineers, a Department of Scientific and Industrial Research-recognised research and development centre in Vadodara, two application centres and pilot processing infrastructure. Its listed infrastructure includes wet and dry processing, calcination, spray drying and advanced analytics.

The company commercialised four breakthrough innovations in FY26 and reports more than 50 specialty products in its current portfolio. The FY26 products include Talc HFM 25 SD for plastic films, White Kaolin for cosmetics, Hypertherm UT for greenhouse films and Hydroxylgel A1 for coatings and construction.

Hydroxylgel A1 is described as capable of replacing up to 50% of organic thickener. 20 Microns also lists collaborations with the Indian Institute of Technology Bombay, the Central Glass and Ceramic Research Institute and the Paint Research Association in the United Kingdom.

In 2026, the company showcased nano-particle inorganic additives at PaintIndia, anti-blocking agents and performance minerals at PlastIndia, and rubber products including Zinkomer, Supermag, K STOFF, Akfleef and Delam barrier clay at India Rubber Expo. These exhibitions covered paints, polymers and rubber, three customer application areas represented in its FY26 revenue mix.

Conclusion

The disclosed figures indicate that 20 Microns bases its customer retention case on qualification and formulation integration rather than mineral volumes alone. Its stated three-to-10-year approval cycle, more than 100 engineered grades and relationships of up to 25 years provide the company’s evidence for recurring supply after a product enters customer production.

The next development to watch is execution of 20 Microns’ FY2030 direction for a rising share of specialty and functional products, supported by Rs 100 crore of capacity expansion, applications beyond paints and research-led launches. The company’s disclosed transition of a leading fast-moving consumer goods customer into commercial supply after nearly 10 years of trials is another relevant measure of the qualification model’s conversion into revenue.
