Patent for an environment friendly, cost-effective and versatile solvent-free white adhesive

National: As one of the global leaders in inks, coatings and adhesives for packaging and labelling applications, UFlex treads on the path of continuous development and delivery of pioneering products for the packaging industry. The Chemicals Business of UFlex has recently acquired a patent for ‘Solvent free pigmented adhesive and a process for its preparation’ (Patent No 406417). With this patent, the Chemicals business of UFlex has once again demonstrated its commitment to 'Harvesting Innovation.'

This patent has been awarded to UFlex by the Government of India in accordance with the provisions of the Patents Act, 1970 for a period of 20 years. UFlex proudly adds this patent to develop innovative and sustainable solution to its growing list of leading-edge products.

The present disclosure relates to a two component adhesive composition and the process for its preparation. The adhesive composition of the present disclosure is solvent-free and works well on existing solvent less lamination machines. It helps reduce the use of white ink, thus significantly reducing costs. The process for the preparation of the adhesive composition is simple, efficient, solvent-free and environment friendly.

Presence of high content of volatile organic solvents in solvent-based conventional adhesives is detrimental to the environment and is energy intensive, thereby increasing overall costs. With the development of this solvent free white adhesive, the customer gets the freedom to be green and cost-effective at the same time.

Advantages of the patented solvent-free pigmented white adhesive:
The adhesive will help achieve higher machine speeds ranging from 300-350 meters per minute, leading to higher productivity with excellent machinability on existing solvent-less lamination machines. This development will cut down the requirement of white ink coating on printed substrates, thereby presenting substantial cost savings. Solvent-free pigmented white adhesive offers excellent wettability, offer enhanced wettability on metallized substrates and improves the look of the packaging. Development of Solvent-free pigmented white adhesive consumes less power and significantly reduces application costs. The fast decay of primary aromatic amines makes it highly environment friendly and sustainable.

On acquiring the adhesive patent, Rajesh Bhasin, Jt. President, UFlex Chemicals stated, “Continuously developing cost-effective and value-added solutions for the packaging industry is integral to our business. Our research team has been continuously working most diligently to outperform our own set benchmarks. This patent is another feather in the cap of UFlex Chemicals, and once again demonstrates our capability to align with client needs while promoting sustainability. I am thrilled that a cost effective and a versatile solvent-free white adhesive is now a reality we will be able to deliver.”

Brands can be highlighted with distinctive visibility as it considerably improves flexible film performance allowing for higher visual appeal in applications. The product is already being marketed globally and is garnering good demand from customers.
