Chennai-based Cabot Sanmar, a joint venture between Cabot Corporation USA and Sanmar Group, is expanding its fumed silica manufacturing capacity in India to meet rising demand. The expansion targets the growing market for CAB-O-SIL branded products, targeted at industries like construction, coatings, and adhesives.
The investment of US$25 million will be in its brownfield facility located in Mettur, Salem district of Tamil Nadu, and is expected to be commissioned by the end of 2027. These two companies have been in joint venture for the past 30 years in India. Cabot has nearly 40 manufacturing plants across the globe, whereas Sanmar has only one plant in Mettur.
Cabot Sanmar’s CAB-O-SIL fumed silica products are widely used across a diverse range of applications including pharmaceuticals, food, paints and coatings, adhesives and sealants, personal care, crop protection, among others.
The company says the expanded capacity will enhance the availability of high-quality fumed silica for domestic customers, supporting India’s growing advanced manufacturing and specialty chemicals sector.
“With this investment, Cabot Sanmar will expand the domestic availability of a critical ingredient that goes into the making of products we use every day,” Dr Krishna Kumar Rangachari, Director, Cabot Sanmar.
“This expansion reflects our shared commitment to collaboration, innovation, and delivering high-quality fumed silica to support India’s growing demand,” Sean Keohane, President/CEO, Cabot Corporation added.
