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 25-75m, 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.

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.

MCS - Moisture Cure Silicone Conformal Coating.

Moisture Cure Silicone Conformal Coating.

4 Litre

Product code: MCS04L

MCS is a low viscosity, solvent free silicone conformal coating featuring a moisture cure mechanism that is designed to be touch dry in 10 mins at ambient temperature of 25°C. A full cure is achieved in less than 48 hours. This cure time may also be accelerated with heat for faster processing.

As a silicone coating it is flexible, with low stress on components (ideal for small or delicate components) As with other silicones, it has a wide operating temperature range of -65°C to +200°C. This makes it especially suited to applications such as the automotive industry, power electronics or other electronic applications which require high temperature performance.

Key Properties:
  • Flexible coating, low stress on components
  • Fast Touch Dry Time (10 mins @ 25°C)
  • Fast Full Cure (under 48 hours)
  • Excellent adhesion.
  • Very Wide operating temperature range
  • Good stability at high temperature.
  • REACH Compliant
  • RoHS Compliant
