Resins for LED lighting manufacturers

8 April 2015 Manufacturing / Production Technology, Hardware & Services Opto-Electronics

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 material that achieves a water-white transparency, ideal for LED potting applications. This RoHS-2 compliant, low-hazard, isophorone diisocyanate-free resin is resistant to weather, 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 – 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 its 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.
