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.

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.

You have a wide range of structural adhesive possibilities here. Normally, you require an adhesive that has been toughened with a rubber for this. Very rigid, quite brittle adhesives have been successful, however.

Ushering growth in the 2020s, legacy players in the adhesives and sealants market are striving to cater to the demands of transportation companies. Traction for adhesives and sealants among manufacturers of cars, buses, trucks, and caravans/recreational vehicles (RVs) has surged in the past several years.

The requirements for the bonding of carbon parts are getting more and more demanding. Kisling, a Switzerland-based manufacturer of adhesives, has developed a new 2K-epoxy to improve bonding performance for a variety of applications in the automotive industry.
