SHOWA DENKO K.K.: Film Adhesive for Bonding Dissimilar Materials
This film adhesive can bond resins like polycarbonate, polyethylene terephthalate, and nylon with metals such as aluminum, iron, and copper.
Showa Denko K.K. (SDK) recently announced that it has developed WelQuick™, a film-type binding material that can quickly bond dissimilar materials together (e.g., resins and metals) with strength. In recent years, manufacturing’s requirements for materials such as lightness, heat resistance, and strength have been advanced so much that almost no single material can meet such sophisticated needs. Therefore, progress has been made in the introduction of composite structure into components, in which dissimilar materials such as resins and metals are bound together. This movement is called “multi-materialization.”
Many methods can be used to bond dissimilar materials, including bonding with liquid or hot-melt adhesives, as well as mechanical fastening with bolts. While manufacturers demand a simple, easy, and timesaving bonding process while securing enough adhesive strength, simultaneous achievement of simplicity and adhesiveness has been difficult.
