Electrolube has launched two new protective and decorative polyurethane resins that will be of particular interest to LED lighting manufacturers.
UR5635 is a two-part, semi-rigid polyurethane resin that produces a ‘hazy/cloudy’ finish, well suited for creating a warm, diffused lighting effect when used as a potting agent for LED installations. Instead of incurring additional costs for plastic light diffusing mouldings, manufacturers of LED luminaires can make use of UR5635′s properties to achieve the same effect, while also providing maximum protection for the LED elements.
UR5635 is an extremely durable, RoHS-2 compliant, low viscosity system, which can be used for a wide variety of applications. Also free from isophorone diisocyanate, the low hazard material has a 1:1 volume mix ratio to facilitate processing and provides high resistance to weather, UV, acids, alkalis, water and mould growth, making it suitable for a wide range of environments.
Electrolube’s UR5634 is another polyurethane resin that is also suitable for LED potting applications. The two-part, semi-rigid UR5634 is an optically clear polyurethane resin that achieves a water-white transparency. This RoHS-2 compliant, low-hazard, isophorone diisocyanate-free material is weather resistant and provides good resistance to acids and alkalis. It is also strongly resistant to yellowing when exposed to UV light – of particular benefit to LED luminaires and light fixings exposed to direct sunlight.
