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.

Two-Part Coating

200ml Sample Kit - 5 Litre

Product code: Sample Kit :- E2K300KIT - Bulk Part A Code*: 2K3005L


2K300 is a highly elastic, solvent-free two-part polyurethane conformal coating. It has been carefully formulated to combine the protection and properties of a resin, while keeping the ease of application. Applied more thickly than the average coating, it provides excellent coverage, even in tight spaces while its extreme flexibility offers protection even around delicate components.

The 2K Range of coatings can be applied using selective coating machines such as PVA using the specially adapted part VPX-2KS) and Nordson Asymtek (using the latest in the AM range).

It displays enhanced thermal performance compared to 2K100, with an operating range of -40 to +130°C while still offering good chemical resistance.

2K300 is a hydrophobic coating which gives excellent water and moisture protection including salt mists making it an excellent choice for automotive electronics.

2K300 is available in bulk, however we have also developed a unique sample kit for the prototyping and validation process, eliminating the need for specialist machine equipment or machine down time.

*Two Part System requires 2K300 as Part A and 2KPB01L as Part B, please refer to the product TDS for recommended mix ratios.
