New Delhi, 6 October 2022 – As one of the global leaders in inks, coatings and adhesives for packaging and labelling applications, the UFlex Chemicals Business 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 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 solutions 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.
The 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 greener and more cost-effective simultaeneously.
Patented solvent-free pigmented white adhesive – advantages
The newly patented adhesive will help achieve higher lamination speeds ranging from 300 to 350 meters per minute, leading to higher productivity with excellent machinability on existing solvent-less lamination machines. Its use will also cut down the requirement of white ink coating on printed substrates, leading to substantial cost savings.
