Electronics Control Unit (ECU)

Electrolube Conformal Coatings, Potting Compounds, Thermal management solutions and other associated product solutions for all areas of the Automotive Electronics industry.
  • 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.

2K300 - Two Part Conformal Coating

2K300
Two Part Conformal 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.
