  • Corrosive Gas Protection
  • Thermal Cycling Resistance
  • Salt Mist Protection
  • Moisture Protection
  • Dust + Environment Protection

The Electronics Control Units are some of the most important parts of a modern vehicle, controlling the majority of the electronics systems on board and connecting with the central / cabin controls. It is important then that the PCB and components of the ECU, which is often exposed to extreme temperature shifts, corrosive gases and other harsh conditions is reliable and protected from corrosion. Electrolube products are created to thrive in such conditions, protecting the PCB and components and ensuring reliability. Electrolube products such as the 2K range have been especially developed for the Automotive industry and offer superb levels of protection.

2K500 - Two Part Conformal Coating

2K500
Two Part Conformal Coating

5 Litre

Product code: Part A Code*: 2K5005L


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 Compliant
  • IPC-CC-830 Approval
  • Meets BMW Group Standard requirement GS95011-5
  • REACH Compliant
