Conformal Coatings

Enhanced protection for enhanced PCB performance

  • 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.

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.

Electrolubes Conformal Coatings Technical Director Phil Kinner recently wrote a micro e-book on conformal coatings for harsh environments. It’s a great little insight into the selection, implementation and testing of protective coating process.

FSC - Flexible Silicone Conformal Coating

Flexible Silicone Conformal Coating

15ml - 400ml - 5 Litre

Product code: FSC15ML - FSC400 - FSC05L

FSC is a specialist conformal coating which has been formulated based on a high quality silicone resin. It is highly flexible for delicate components, while it exhibits excellent adhesion to a wide variety of substrates and operates within a wide temperature range. It's an ideal choice for humid environments offering excellent protection from moisture.

It can be sprayed, dipped or brushed and is fast drying, allowing for efficient production while it also contains a UV trace, which allows inspection of the PCB after coating to ensure complete and even coverage. FSC is widely used through the rail industry, but is suitable for a rage of high end applications. 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.

We also have available FSCP (plus) which offers enhanced adhesion to a variety of substrates, including solder resists with low surface energy, for full details see the TDS below.

Key Properties:
  • Flexible
  • Transparent
  • Very high surface insulation resistance
  • Wide operating temperature range
  • High level of protection offered in humid environments
  • May be removed with solvents such as Ultrasolve (ULS)
  • May be soldered through for rework
  • RoHS Compliant
  • IEC 61086-2
  • IPC-CC-830
  • MIL-I-46058-C
  • UL94V-1
