UFlex chemicals business secures India patent for new process to derive epoxy ester resin 

The company plans for a global patent in due time  


The chemicals business of UFlex Limited has secured a patent on ‘a process for the preparation of Epoxy Ester Resin’ in accordance with the provisions of the Patents Act, 1970. This is the first patent for chemicals business ever in India and it will be considering applying for a global patent in due course of time, Uflex said.

UFlex’ chemicals business is a leading manufacturer of Inks, coatings and adhesives for flexible packaging, cartons, labels, and paperboard.

According to the company, the new patent will ensure technical advancement in providing a process for resin preparation wherein no waste water treatment is required which is a significant move in the direction of sustainability.

Furthermore, Epoxy Ester Resin prepared by this process will be used in radiation curing or energy curing and therefore curing will be faster, unlike the typical Epoxy Ester resin which is thermally cured and takes a longer time besides being uneconomical. With enhanced stability of coating and its chemical resistance attributes a total of 16 claims have been taken under this patent.

We are extremely delighted with the continued strengthening of our R&D prowess. The issuance of this patent is another step in the development of a robust portfolio for our business,” Rajesh Bhasin, joint president, chemicals division, UFlex Limited said. “This is part of our initiative to backward integrate, using our inherent strengths. Such initiatives help us to have greater control on product quality and supply security. This unique achievement is all because of the progressive approach, years of hard work and commitment.”  

UFlex’s newly invented and patented approach arrests the challenges posed in a conventional method as the Epoxy ester produced has no wastewater generation, no odor and neither a dark color which is good for fast curing coatings with efficient cost-effective processing, the company said.
