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.

The use of conformal coatings is particularly important in automotive, military, aerospace, marine, lighting, industrial and green energy applications. Due to the rapid expansion of the electronics industry, conformal coatings are also finding their way into the domestic and mobile electronics industries, providing the necessary combination of high performance and reliability within a vast array of electronic devices.

Conformal coatings can be used in a wide range of environments to protect printed circuit boards from moisture, salt spray, chemicals and temperature extremes in order to prevent corrosion, mould growth and electrical failures, for example. The protection provided by conformal coatings allows for higher power and closer track spacing, in turn enabling designers to meet the demands of miniaturisation and reliability.

Electrolube is among the world’s foremost experts in the formulation and application of conformal coatings designed to meet international approvals (including European and American military specifications). The range of products currently available comprises acrylics, silicones, polyurethanes, hybrid chemistries and environmentally friendly options.

Electrolube can offer both transparent and pigmented coatings to improve or camouflage the appearance of printed circuit boards. The range also includes a number of ancillary products to complement the use of our conformal coatings, including thinners and removers, peelable coating masks and thixotropic materials for dam and fill applications.

Product code: PUC400 - PUC05L


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
