  • Sealing and protection
  • Cable jointing
  • Coloured and optically clear
  • Bespoke and ex-stock

Resin systems are designed to protect and insulate printed circuit boards (PCBs) and electronic components from the threats of harsh and challenging environments, including; moisture, vibration, thermal or physical shock and general contamination. By encapsulating the entire device, resins can form a complete barrier against such environments offering superior performance under extreme conditions.

Potting and encapsulation resins also offer excellent mechanical protection. Mechanical protection can be identified in a number of ways; superior performance is evident in applications involving prolonged exposure or immersion in harsh chemicals, or those exposed to vibrational, thermal or physical shock, for example. The higher level of protection is achieved through the mass of the resin surrounding the unit. This is different for every application however potting and encapsulating resins always provide a far more substantial covering than thatoffered by conformal coatings.

Due to the bulk of material surrounding the PCB, potting and encapsulation resins are commonly two-part systems which when mixed together form a solid, fully cured material, with no by-products. In cases where the conditions are not considered extreme, Electrolube offer a range of conformal coatings which provide a combination of protection in humid and corrosive environments with ease of application. They can be used for complete coverage or selective application onto the PCB, thus minimising the weight added as a result of applying a protective material.

ER2222  - Red Thermally Conductive Epoxy

ER2222
Red Thermally Conductive Epoxy

5kg - 25kg

Product code: ER2222K5K - ER2222K25K


ER2222 is a red variation of Electrolube's ER2221 Thermally conductive Epoxy potting compound. The resins properties are identical to ER2221 but has been formulated with a red finish for aesthetic appearance.

It's a highly temperature resistant epoxy with excellent thermal conductivity and a wide operating temperature range -40°C to +150°C retaining excellent characteristics even through extensive thermal cycling.

Although ER2222 is a filled system, it is easy to mix and has a low viscosity allowing the resin to flow around and under tricky components or into tight spaces.

ER2222 are an excellent choice for encapsulating an electronic device which requires high levels of thermal resistance and protection such as automotive, aerospace, industrial or other applications which are subject to harsh environments.


Key Properties:
  • Two component red epoxy resin
  • Excellent high temperature resistance up to 150°C
  • Enhanced thermal conductivity
  • Low viscosity for a filled system;
  • Does not contain abrasive fillers; low wear on dispensing machinery
  • Meets UL94 V-0
  • RoHS Compliant
