Encapsulation Resins

Meeting the challenge of challenging environments

  • UL approved
  • Potting / encapsulating
  • 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.

ER1455, Discontinued
Black Epoxy Resin

250g - 5 KG

Product code: ER1455RP250G - ER1455K5K

This Product Has been Superseded with: ER2223RP250G / ER2223K5K

The following product has been discontinued and superseded with the listed replacement. While the replacement product will exhibit improved characteristics, we would always advise further testing to ensure the product is suitable for your application. '

ER1455 is a two part chemically resistant epoxy resin which has been carefully formulated to withstand a wide range of harsh chemicals and solvents including fuels. The resin system does not contain any solvents or unreactive diluents and therefore is a 100% reactive system offering the highest level of protection even in the harshest of environments. It can be cured at ambient temperature or accelerated using heat.

It also exhibits good thermal resistance with a wide operating temperature range and offers good adhesion to a wide range of substrates.

It is an ideal choice for applications such as automotive sensors exposed to harsh fuel and oil.

Key Properties:
  • 100% reactive system;
  • highest level of performance in harsh environments
  • High chemical resistance
  • Good adhesion to a wide variety of substrates
  • Wide operating temperature range
  • Excellent thermal resistance
  • RoHS Compliant
