From automotive and construction to general industrial applications, the use of adhesives and sealants is expanding in assembly operations around the world.
We’re focusing on adhesives in assembly applications in this issue of ASI, and it’s always exciting to see the industry’s development of new technologies in this sector, as well as the increasing willingness of OEMs and others to accept them.
Vehicle manufacturers are improving fuel economy while reducing emissions by lightening the overall weight through material replacement. Using thermoplastics and adhesives instead of traditional screws and metals create less weight.
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.
Environmentally friendly cleaning and preventative maintenance can pay dividends in terms of efficient operation and a safer manufacturing environment.
Have you ever run your hot-melt tank above the adhesive manufacturer’s recommended operating temperature? Did someone on the line ever forget to turn the equipment off at the end of the day? What about drips on the tank lid, or that one spot on the nozzle that always seems to collect buildup?
As part of a collaborative project focusing on coatings and joining systems for lightweight materials, the U.S. Army Combat Capabilities Development Command (DEVCOM) Army Research Laboratory (ARL) tasked PPG to develop a high-strength, highly ductile structural adhesive to meet the requirements of the U.S. Department of Defense’s (DoD) test method standard MIL-PRF-32662, Tier I-III specification. MIL-PRF-32662 incorporates a decade of rigorous research efforts to statistically correlate the complex ballistic response of adhesively bonded armor assemblies to universally translatable and commercially relevant quasi-static mechanical properties.
Recent innovations in the electronics industry, such as hybrid vehicles, mobile electronic devices, medical applications, digital cameras, computers, defense telecommunications, and augmented reality headsets, touch nearly every part of our lives.
The company reports that the approximately $2.1 million investment is in response to increasing customer demand for its products.

Scott Bader recently announced that it has made a capital investment to expand production capacity for its range of Crestabond® and Crestomer®structural adhesives, Crystic® gelcoats, and formulated products.
The company reports that it is seeing increased demand, especially in the UK where the polyurethane tooling board industry is now more focused on quality and durable supply chains.

Ru-bix recently announced that it is gearing up for full production this month, which will involve utilizing a tripling of capacity.
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.
