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.

The global pandemic has accelerated demand for manufactured goods of many types, as consumers stay home and manufacturers continue to operate as essential businesses.

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.

Among all chemical curing techniques, convection and radiant thermal curing represent the most widely used applications for adhesives and sealants. During the curing process, adhesives and sealants usually pass through two physical transformations—evaporation and condensation—while being applied to other materials.
