Latest Patents

Dhiren's recent patents showcase his expertise and dedication to improving manufacturing processes. His first patent introduces systems and methods for laminating aluminum can end stock. This innovation features an adhered polymer coating that exhibits low feathering and exceptional performance in various acid tests. The key to this advancement lies in incorporating a copolymer adhesion promoter film to an aluminum alloy prior to lamination. In certain applications, the metal strip receives a pretreatment with a conversion layer that contains trivalent chromium compounds and phosphates or titanium and zirconium.

His second patent revolves around laminated can end stock with elevated temperature annealing, resulting in a laminated, amorphous polymer coating with low feathering and low blushing. This novel product demonstrates excellent performance in acetic acid tests as well. The laminated metal strip is designed with a polymer coating on one side and a lacquered finish on the other. The annealing process utilized raises the metal strip to a temperature above the polymer’s melting point for an adequate duration, which allows the polymer to become amorphous. In some instances, the polymer film laminated onto the metal strip is a Polyethylene terephthalate (PET) film.
