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.

UR5640 - Optically Clear Polyurethane Resin

UR5640
Optically Clear Polyurethane Resin

250g - 5kg

Product code: UR5640RP250G - UR5640K5K


UR5640 is an optically clear resin making it ideal for LED encapsulation, suitable for aesthetic as well as protective application over the top of the luminaire. Due to the aliphatic chemical nature of the resin chemistry, the cured UR5640 is naturally resistant to the yellowing effects of UV light, making it useful for a range of outdoor applications. UR5640 shows excellent weather resistance, as well as chemical resistance against a range of chemicals. This enables this clear, though yet flexible resin to be used in a range of applications, both indoor or out.


Key Properties:
  • Water white transparency
  • Ideal for LED applications
  • Excellent resistance to yellowing effects of UV light
  • Excellent scratch and mark resistance
  • High resistance to weather, acids and alkalis, water and mould growth
  • Excellent processability
  • RoHS-2 Compliant
