Consultant POV

“Conformal coating is the reliability insurance of electronics manufacturing — a small material cost that prevents catastrophic field failure. The market grows with electronics proliferation and gets more interesting as electronics move into harsher environments. UV-curable and selective coating are the processing innovation story; nano-coating and parylene are the performance frontier. The biggest structural growth driver is the EV and renewable energy transition moving high-power electronics into outdoor and thermally challenging environments that demand coating protection that traditional consumer electronics never needed.”
