Continuous price fluctuation of crude oil and eco-friendly approach has stimulated the development of products from renewable resources as an alternative; among which, vegetable oils are one of the most preferred because they are easily available, sustainable, and cost-effective. India is a major source of various vegetable oils. The anticipated vegetable oil production from 45.64 million tonnes of oilseeds in the year 2022 is 13.69 million tonnes. Thus, efforts are being made to achieve a renewable approach via the utilization of vegetable oils as a fundamental material for the synthesis of raw materials.

High molecular weight pigment hyper-dispersants with a molecular weight greater than 1000 Daltons and flexibility towards application into different binder and pigment-based printing ink formulations are particularly suitable for food packaging application.

Keeping this in mind, the R&D team of Yansefu recently developed a high-end hyper-dispersant SARJOADD-HDA primarily aiming at various ink systems including polyurethane-based inks for gravure and flexographic applications. SARJOADD-HDA is intended to provide a strong attraction for pigment surfaces and stabilizes against re-aggregation of the dispersed pigment particles.

This hyper-dispersant uses cutting-edge dispersion control technology which can stabilize both organic and inorganic pigments from flocculation and thereby increases the shelf life of inks. It also supports stabilizing a narrow and uniform particle size distribution of pigments inside the ink matrix, which improves the ink printability.

“Innovation and sustainability should go in parallel and our team is fully determined to meet these challenges. Focus on sustainability and development of regulatory compliance products is in the DNA of Yansefu,” says JK Sharma, CEO, Yansefu Inks and Coatings.
