The use of adhesives in electric vehicles (EVs) is even more widespread than in conventional automobiles. In both types of vehicles, adhesives offer many advantages, including ease of use compared to welding, environmental resistance, sealing, distributing stress, and joining dissimilar materials.
The new versatile and single-component hot-melt polyurethane reactive range has been designed specifically for the manufacture of miniaturized handheld and wearable electronic devices.
Called thermoset polyesters, these materials are glass fiber-reinforced unsaturated polyesters. They are also often referred to as “sheet molding compounds” (SMCs), “fiber-reinforced plastics” (FRPs), or simply “fiberglass.”
I have worked with companies that manufacture superglue and polyurethane glue, both of which are single-component, no-mix adhesives. Superglue, which is the common term for cyanoacrylate adhesive, has been around for about 60 years. In contrast, the polyurethanes are about 20 years old in the retail market and somewhat older in professional woodworking. I admit to using both types of adhesive regularly.
I realize that the meter/mix equipment can be a major inconvenience. Adhesives come in two forms, namely two component or one component. Two-component adhesives are mainly epoxies, reactive acrylics, or polyurethanes.
CMC, which will be 51% owned by Bostik for an investment of around $11 million, will produce specialty cyanoacrylate monomers on an industrial scale at a competitive cost.
Arkema recently announced an investment in Crackless Monomer Co. (CMC), a joint venture between Bostik and Taiwanese company Cartell Chemical Co., to accelerate the development and production of high-value-added engineering adhesives.
Adhesives can be classified in several ways, including their material origin (e.g., natural or synthetic) and their type of cure (e.g., physical curing such as drying or chemical curing).
Adhesives and surgical sealants are used during medical procedures to fill surgical wounds, rebuild injured tissues, and replace and improve common stitching in medical practices.
The global market for surgical sealants and adhesives is forecasted to top $3.5 billion by the end of 2026, growing at a CAGR of over 9.3% from 2019-2026.
