Electrolube’s New Polyurethane Resins for LED Applications

Electro-chemicals specialist, Electrolube has launched two new protective and decorative polyurethane resins that will be of particular interest to LED lighting manufacturers.

The first of these - UR5634 - is a two-part, semi-rigid, optically clear polyurethane resin that achieves a water-white transparency, ideal for LED potting applications. This RoHS-2 compliant, low-hazard, isophorone diisocyanate-free material is weather resistant, as well as 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.

Another two-part, semi-rigid polyurethane resin - UR5635 - will also be shown. Similar to UR5634, however, this produces a ‘hazy/cloudy’ finish that is ideal 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.

As an ISO 14001 qualified manufacturer of specialist chemical products supplying the world’s leading manufacturers of electronic, industrial and domestic devices, Electrolube is a trusted provider of high performance chemical solutions, formulated with the utmost responsibility to the environment and operator.
