Encapsulation Resins

Meeting the challenge of challenging environments

Electrolube resins in use.
  • 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.

UR5547 - Black Polyurethane Resin

UR5547
Black Polyurethane Resin

250g - 500g resin packs - 5kg - 10kg kits

Product code: UR5547RP250G - UR5547RP500G - UR5547K5K - UR5547K10K


UR5547 black Polyurethane potting and encapsulation resin is a semi-rigid compound ideally suited to electronics with small or delicate components, as the cured resin exhibits very little stress on components, even when thermally cycled.

Its adhesion to a wide range of substrates and low water absorption make it a great choice for cable joining applications. While it is also a thermally conductive resin, dissipating heat away from delicate components making it a suitable in a wide range of electronic applications .

UR5547 is also flame retardant to a UL94-V0 approval and are RoHS Compliant


Key Properties:
  • Semi rigid, flame retardant casting resin
  • Thermally conductive polyurethane resin
  • High thermal shock resistance
  • Low Water absorption
  • Excellent adhesion to a wide variety of substrates
  • Ideal for use in potting or cable jointing applications
  • UL94 V-0 approval
  • RoHS Compliant
