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.

This Product Has been Superseded with: UR5634, UR5638 and UR5640

The following product has been discontinued and superseded with the listed replacement.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. '

UR5562 is a Semi-rigid, optically clear polyurethane potting compound.

Due to its careful chemical makeup, it is extremely durable and therefore suitable for a range of applications.

Its excellent resistance to scratching or marking give a good cosmetic appearance, along with its water white transparency, make it an ideal choice for LED potting and encapsulation.

It also displays a high resistance to weather, UV light and and mould growth making it a good choice for exposed applications such as outdoor lighting.

It also maintains a high resistance to acids and alkalis giving it good scope for different environments.

Key Properties:
  • Water white transparency, ideal for potting LEDs
  • Excellent resistance to yellowing when exposed to UV light
  • Excellent scratch and mark resistance
  • High resistance to weather, acids and alkalis, water and mould growth
  • RoHS Compliant
