Electrolube's protective and decorative polyurethane resins are engineered for manufacturing LED lighting products

Dec. 1, 2014
Electrolube will also showcase at Southern Manufacturing & Electronics Show, Farnborough, UK, 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 offers a high level of protection in a range of environments. It is also strongly resistant to yellowing when exposed to UV light – of particular benefit to LED luminaires and light fixings.

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

Like UR5634, UR5635 is a RoHS-2 compliant, low-hazard, isophorone diisocyanate-free material and offers a high level of protection in a range of environments. Both materials also have a simple 1:1 by volume mix ratio and low viscosity, thus improving the efficiency of the potting process.

The company will also present its AFA aromatic-free acrylic conformal coating for the protection of electronic circuits. Formulated without the use of hazardous aromatic solvents such as Toluene and Xylene, it is UL746-QMJU2 compliant, achieves flame retardancy to UL94 V-0, and meets IPC-CC-830 and MIL-1-46058C approvals. AFA is ideal for those applications requiring rework, being easily removed using Electrolube’s ULS cleaning solvents.
