Conformal Coatings

Enhanced protection for enhanced PCB performance

An Electrolube brand conformal coating product on printed circuit board undergoing UV cure.
  • UL, MIL and IPC-CC-830 approved
  • Solvent removable and solvent resistance coatings
  • Acrylic, Silicone, Polyurethane and Hybrid Materials
  • UV cure and water-based options available
  • UV trace to aid inspection
  • Thinners and masking products

Conformal coatings are designed to protect printed circuit boards and related equipment from their environment. Typically applied at 25-75μm, these coatings ‘conform’ to the contours of the board allowing for excellent protection and coverage, ultimately extending the working life of the PCB.

PUC is a clear amber modified Polyurethane Conformal Coating, specifically designed for the protection of electronic circuitry. PUC is tough and has excellent mechanical and dielectric properties while maintaining flexibility to protect delicate components.

PUC can be sprayed, dipped or brushed. The thickness of the coating depends on the method of application (typically 25-75 microns). Temperatures of less than 16°C or relative humidity in excess of 75% are unsuitable for the application of PUC. As is the case for all solvent based conformal coatings, adequate extraction should be used (refer to MSDS for further information) For full product details including test results please refer to the TDS below. If you still require further information please don't hesitate to get in touch.

Key Properties:
  • Excellent abrasion resistance and mechanical strength
  • Excellent adhesion under all climatic conditions
  • Excellent resistance to a wide range of chemicals and solvents
  • UV trace to aid inspection
  • High level of flexibility, even at low temperatures
  • Resistant to mould growth
  • RoHS-2 Compliant
  • Meets MIL-1-46058C
  • Meets IPC-CC-830
  • DEF-STAN 59/47
