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.

Product code: Part A Code*: E2K500A5L


2K500 is a hard, two-part polyurethane conformal coating system which provides the protection properties of an encapsulation resin, with the ease of application of a conformal coating and without the use of harmful solvents. It can be easily applied to provide excellent coverage, even areas with difficult geometries and maintains clarity even after prolonged exposure to UV light.

It is more abrasion resistant than 2K100 or 2K300 and has a wider operating temperature range providing protection for electronics exposed to temperature over a long period of time, as well as providing excellent thermal shock resistance.

2K500 is applied using selective coating machines from PVA (using the specially adapted part VPX-2KS) and Nordson Asymtek (using the latest in the AM range).

*Two Part System requires 2K500 as Part A and 2KPB01L as Part B, please refer to the product TDS for recommended mix ratios.


Key Properties:
  • Two-part conformal coating
  • Wide operating temperature range
  • Good abrasion resistance
  • Excellent thermal shock performance
  • Maintains good clarity even when exposed to UV light
  • Excellent coverage, even over difficult geometries
  • RoHS-2 Compliant
  • IPC-CC-830 Approval
  • Meets BMW Group Standard requirement GS95011-5
  • REACH Compliant
