Latest Patents

Dinh's latest patents include a laminate food packaging material and a method for producing laminate. The first patent describes a laminate film that consists of a substrate, a polyurethane layer formed on the substrate, and a metal vapor deposition layer formed on the polyurethane layer. The method involves applying a coating liquid on the substrate, which is then dried to produce the polyurethane layer. This coating liquid contains a water-dispersible polyisocyanate and a polyurethane dispersion made from a reaction of an isocyanate group-terminated prepolymer with a chain extender. The prepolymer is produced by reacting a polyisocyanate component, including xylylene diisocyanate, with a polyol component that has a hydrophilic group.

The second patent focuses on a laminating adhesive prepared from a water-borne resin. This resin is created by allowing an isocyanate group-terminated prepolymer with an anionic group to react with a chain extender, along with a swellable inorganic layer compound and a water-dispersible polyisocyanate curing agent.
