Silicones safeguard high-power modules and LED lighting against -55 °C to +200 °C swings, critical for automotive under-hood and avionics.

• Urethane – Tough, chemical-resistant.
Preferred in fuel-vapor zones and harsh industrial plants where aggressive solvents threaten circuitry.

• Epoxy – Rigid, abrasion-resistant.
Used in white goods and power tools where boards face mechanical wear.

• Parylene – Ultra-thin, pinhole-free.
Vacuum-deposited parylene serves implantables and MEMS sensors that demand biostability and sub-micron coverage.

By Operation Method

• Spray Coating – High throughput.
Automated selective-spray systems dominate modern SMT lines, delivering uniform films on complex geometries with minimal overspray.
