  • LED Encapsulants
  • Conformal Coating for LEDs
  • LED potting compounds
  • Optically Clear Resins
  • Light Diffusing Resins
  • Flame Retardant Optically Clear

The protection of an LED Luminaire and the supporting components is an important consideration for many LED designers. With the LED market expanding into more and more sectors, so too is the need to protect LEDs from the vast variety of different operating environments in which the LED is expected to perform.

UR5644 - Flame Retardant Cloudy/Hazy Polyurethan

UR5644
Flame Retardant Cloudy/Hazy Polyurethan

250g - 5Kg

Product code: UR5644RP250G - UR5644K5K


UR5644 is a flame retardant polyurethane resin / potting compound which has a hazy, light defusing effect ideal for potting LEDs. It is flame retardant and will pass UL94 V-0 (approval pending) making it an excellent choice for LEDs used in Hazardous or ATEX areas giving a softer light than the optically clear UR5641 while still offering excellent levels of protection. UR5644 is based on the same halogen free aliphatic chemistry as UR5641, offering resistance to the yellowing effects of UV light as well as good chemical resistance while allowing the transfer of the majority of RF radio frequencies with the minimal of scattering.

UR5644 has good adhesion to a wide range of substrates meaning it can be used to encapsulate any number of components that require a high level of flame retardantcy while it also offers good chemical resistance and low water absorption.


Key Properties:
  • Hazy Light Diffusing Effect
  • Flame retardant UL94 V-0 (pending)
  • Resistant to UV yellowing
  • Excellent for the protection of LED's in hazardous environments
  • Halogen free
  • Good Adhesion
  • Good Chemical resistance
  • RoHS Compliant
