Transportation electronics in both battery electric vehicles (BEVs) and autonomous vehicles regulate crucial on-board domains such as drive control units, safety systems, proximity sensors, and connectivity controllers. The electronics in these increasingly sophisticated computers are susceptible to corrosion failures from exposure to water and salt during vehicle operation that can result in performance problems, loss of function, and expensive repairs.

To protect these electronics, suppliers of automotive electronics modules often use cure-in-place liquid adhesives or sealants. Suppliers, however, must differentiate among a variety of material types to select high-performance solutions to continuously protect crucial systems through many years of service life.
