Electro-chemicals specialist, Electrolube launched a new contamination removal product at Southern Manufacturing 2015, that the firm says is set to become the de facto standard for electronics manufacturers. The new product was one of a number being showcased at Farnborough this year, including two protective and decorative polyurethane resins of particular interest to LED lighting manufacturers.
UR5634 is a two-part, semi-rigid, optically clear polyurethane resin that achieves a water-white transparency, ideal for LED potting applications. The RoHS-2 compliant, low-hazard, isophorone diisocyanate-free material is weather resistant, as well as being impervious 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.
A second semi-rigid polyurethane resin, UR5635 was also highlighted. Similar to UR5634, except producing a ‘hazy/cloudy’ finish that the firm says 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.
UR5634, UR5635 is a RoHS-2 compliant, low-hazard, isophorone diisocyanate-free material that is also UV and weather resistant, as well as being impervious to acids and alkalis.
The company also presented 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 suited to those applications requiring rework, being easily removed using Electrolube’s ULS cleaning solvents.
