LED Driver Protection

The LED driver is a crucial element to the unit, powering and regulating the LED during use, protection is vital.
  • PCB Coating
  • Thermal Management
  • Potting Compounds
  • Encapsulation Resins

The LED driver is a crucial element to the unit, powering and regulating the LED during use. Whether the driver be directly installed with the LED or housed within a separate unit itself, it is important to protect the driver to maintain efficiency in any operating environment. Electrolube offer a wide selection of thermal management products, coatings and encapsulants - find your Electrolube solution.

The LED driver is should not be overlooked when considering a design, both the environmental protection of the unit and the thermal management can play a crucial part in efficiency. As with any power electronics unit, thermal management is a key consideration utilised to dissipate heat away from the unit; this is particularly important in LED designs where the Luminaire is housed with the driver, (see Thermal Management of LEDs). The second consideration is the protection of the PCB from the environment. As is discussed in Protection of LEDs the entire unit can be potted in order to provide complete protection, however in less extreme environments a conformal coating may be a more cost effective option. Electrolubes 2K materials also offer ‘the best of both worlds’ providing protection for both the PCB and the Luminaire from the environment without the need to fully pot the unit and 2K500 has been used in LED applications such as street lighting.

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
