Showa Denko Develops WelQuick(TM) to Bond Dissimilar Materials Quickly
TOKYO, Jun 28, 2021 - (JCN Newswire) - Showa Denko K.K. (SDK; TSE:4004) has developed "WelQuick(TM)," a film-type binding material to bond dissimilar materials together, such as bonding between resins and metals, with excellent quickness and strength. SDK has already started to provide potential customers with samples of WelQuick.

In recent years, manufacturing industry'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, there has been a progress in introduction of composite structure into components, in which dissimilar materials such as resins and metals are bound together. This movement is called "multi-materialization." There are many methods to bond dissimilar materials, such as bonding with liquid adhesives or hot-melt adhesives, and mechanical fastening with bolts. Though manufacturers demand simple, easy and timesaving bonding process while securing enough adhesive strength. However, simultaneous achievement of simplicity and adhesiveness has been difficult.
WelQuick, which has been developed by SDK, is a film-type adhesive component, and eliminates the process to apply liquid components which was necessary process for reactive adhesives. Therefore, WelQuick is easy to handle, and shortens bonding time to a few seconds by utilizing the phase change between solid and liquid, while bonding with conventional adhesives takes dozens of minutes.
WelQuick can bond resins and metals. The former includes polycarbonate, polyethylene terephthalate and nylon, while the latter includes aluminum, iron and copper. SDK has confirmed that WelQuick can achieve shear adhesive strength of more than 10MPa with more than 40 combinations of base materials. Moreover, our customers can choose welding method suitable for their needs from wide variety of welding methods including ultrasonic welding which realizes high-speed welding, electromagnetic induction welding which is suitable for metals, and heat welding which is suitable for various materials. Furthermore, films of WelQuick can be stored at room temperature for long periods. WelQuick does not produce volatile organic compounds (VOCs) when welded. Thus WelQuick lowers the burden on the environment.
On the basis of these strong points, WelQuick can contribute to customers' cost reduction and reduction of CO2 emission through improvement in efficiency of production processes.
The Showa Denko Group has wide-ranging technologies and materials concerning inorganics, organics and aluminum. By fusing these technologies into one, the Group will provide various business fields, where multi-materialization is in progress, with new solutions, and aim to maximize the value of Customers' Experience.

Comparison of WelQuick bonding method and conventional bonding method
 Phase change: Changes in the state of material (gas, liquid and solid) caused by changes in temperature and pressure. WelQuick(TM) technology utilizes liquefaction of solid and solidification of liquid.
 Shear adhesive strength: Adhesive strength that acts on the surfaces of adhered materials parallel to adhered surfaces when the base materials are pulled to opposite directions to slide laterally.
 MPa (Mega Pascal): The SI unit of pressure. If the two sample materials show shear adhesive strength of 10MPa, one square centimeter of adhered surface requires forces of about 100kg to be peeled off.
