Conformal Coatings
Thin protective coatings that shield printed circuit boards from moisture, dust, chemicals and corrosion.
Protect PCBs in Harsh Environments
A conformal coating is a thin protective film applied over a populated circuit board. It ‘conforms’ to the board’s contours, protecting components and solder joints from moisture, dust, salt spray, chemicals and temperature extremes.
JOME supplies conformal coatings for spray, brush and dip application, helping electronics survive automotive, outdoor, industrial and marine conditions.
Conformal Coating Benefits
Moisture Protection
Guards against humidity, condensation and water ingress.
Dust & Contaminant Barrier
Keeps dust, debris and airborne contaminants off the board.
Improved Insulation
Reduces the risk of shorts, dendrites and current leakage.
Easy Application
Spray, brush or dip grades to suit your process and volume.
Conformal Coating Range
Acrylic Conformal Coatings
Easy to apply and rework, with good general protection.
Silicone Conformal Coatings
Flexible, high-temperature protection for harsh environments.
Polyurethane Conformal Coatings
Tough chemical and abrasion resistance for demanding use.
Conformal Coating Applications
- Automotive electronics
- Industrial control boards
- Outdoor and telecom equipment
- LED lighting electronics
- Marine and offshore electronics
- Aerospace and defence boards
- Consumer electronics
- Power and energy systems
Frequently Asked Questions
A conformal coating is a thin protective layer applied to a circuit board that conforms to its shape and protects it from moisture, dust, chemicals and corrosion.
They can be sprayed, brushed or dip-applied, then cured by air, heat or UV depending on the chemistry. We can advise the best method for your volume.
Conformal coating applies a thin protective film over a board, while potting fully encapsulates the assembly in a solid block. Coatings are lighter; potting gives maximum protection.
