Introduction

David Wen-Lung Chang is a notable inventor based in Troy, MI (US). He has made significant contributions to the field of adhesive technologies, holding 2 patents that showcase his innovative approach to creating advanced adhesive systems.

Latest Patents

One of his latest patents is for a two-component, curable hot melt adhesive. This system includes a first hot melt adhesive formulation with a softening temperature greater than room temperature, which contains a first component of a curable adhesive. The second formulation also has a softening temperature above room temperature and includes a second component that reacts with the first to create a durable adhesive bond. When heated and mixed, the resulting thermoplastic bond cures to form a permanent adhesive bond, enhancing performance across various temperature ranges.

Another significant patent involves a radiation-cured, non-blocking heat-activated label adhesive and coatings. This innovative coating composition includes a curable acrylic material, a curable elastomeric material, and a hydrocarbon tackifier. The composition remains non-blocking at room temperature but becomes adhesive when heated above the tackifier's softening temperature, demonstrating versatility in adhesive applications.
