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 Compliant
