Title: Jum-kyun Lee: Innovator in Aqueous Polyurethane Emulsion Technology.

Introduction

Jum-kyun Lee is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of polyurethane technology, particularly through his innovative patent related to aqueous polyurethane emulsions.

Latest Patents

His most recent patent is titled "Aqueous polyurethane emulsion composition and polyurethane film using the same." This invention provides an aqueous polyurethane emulsion composition that features a urethane-urea bond. The composition is created by reacting a polyisocyanate, a polyester polyol, and an ionic compound to prepare a polyurethane prepolymer. This prepolymer is then neutralized with an alkali or trialkylamine, dispersed in water, and reacted with an amine, which serves as a chain extender. The resulting polyurethane gloves manufactured with this emulsion exhibit superior antistatic properties, which are maintained even after washing. Additionally, they offer wearing comfort comparable to gloves made of natural latex and do not cause allergic reactions.
