Values are typical reference ranges and may vary depending on material chemistry, thickness, substrate condition, curing process, application method and validation standard.

Power electronics are the control core of EV, inverter and energy storage systems. They are exposed to moisture, contamination, vibration, dielectric stress and heat, so material selection directly affects long-term reliability. Conformal coatings shield PCBs from moisture and contamination, potting compounds insulate and protect high-voltage assemblies, and thermal interface materials pull heat out of power modules. VAMS supplies all three, validated for demanding automotive and industrial electronics.

VAMS supplies conformal coatings, potting compounds, and thermal interface materials covering every protection requirement for PCBs and power electronics

Three Failure Modes — Three Material Answers

Electronics assemblies fail in three main ways: moisture and contamination corrode tracks and cause leakage between conductors; high voltage arcs across insufficient insulation; and heat from power devices accumulates until junctions exceed their limits. Each failure mode has a dedicated material answer.

VAMS supplies conformal coatings for environmental protection, potting compounds for dielectric isolation and mechanical protection, and thermal interface materials for power-device cooling — covering the full electronics protection stack from signal PCBs to high-power inverters.

• Moisture / corrosion / contamination → conformal coating
• Dielectric stress / vibration / mechanical shock → potting or encapsulation
• Heat / high power density → TIM, thermal pad or gap filler

Conformal Coating for PCB Protection

A thin conformal film (25–100 µm) protects PCBs against moisture, dust, and chemicals — applied by selective, dip, or spray coating

A conformal coating is a thin protective film (typically 25–100 µm) that follows the contours of a populated PCB, sealing it against moisture, dust, condensation, and chemical contamination — the leading causes of field failure in automotive and industrial electronics. VAMS offers a full chemistry range so the coating can be matched to the operating environment:

Potting for High-Voltage Electronics

Engineered potting encapsulates high-voltage assemblies for dielectric isolation, vibration damping, and full environmental sealing

Potting fully encapsulates a high-voltage assembly in a cured resin, providing dielectric isolation between conductors, mechanical protection against shock and vibration, and a complete barrier against moisture and contaminants. VAMS supplies epoxy, polyurethane, and silicone potting systems selected for dielectric strength, thermal class, and flexibility:

Thermal Interface Materials for Power Modules

Thermal grease, pads, and gap fillers move heat from power devices to the heat sink — keeping junction temperatures within limits

Power devices — IGBTs, MOSFETs, and SiC modules — generate intense, concentrated heat that must reach the heat sink before junction temperatures exceed their limits. VAMS thermal interface materials fill the microscopic air gaps between device and heat sink with a continuous, high-conductivity path:
