Electrolube to launch innovative resins at Productronica 2017

Two new optically clear polyurethane resins - UR5640 and UR5641 - offer ‘water white’ transparency, making them well suited for encapsulating LED luminaires. UR5640 cures to provide a flexible, protective and aesthetically pleasing covering over the luminaire elements, and the aliphatic chemical nature of the cured resin is naturally resistant to the yellowing effects of UV light, making it useful for a range of outdoor applications. UR5640 is also scratch resistant and offers high resistance to weather, acids and alkalis, water and mould growth.

UR5641 has similar optical properties to UR5640 but with the added bonus of being flame-retardant and eminently suitable for the protection of LED luminaires exposed to hazardous atmospheres, such as emergency lighting, or lighting intended for installation in ATEX rated/zoned environments. The resin’s halogen free aliphatic chemistry ensures resistance to the yellowing effects of UV light, again making it useful for both exterior as well as interior applications.

The third resin to be launched by Electrolube at this year’s Productronica is the ER2225 RoHS-2 compliant, black epoxy potting compound, formulated to meet the exacting requirements of the automotive sector and other industrial applications that require high temperature resistance, good thermal cycling performance and the ability to withstand attack from a wide range of chemicals, fuels and aggressive fluids.

ER2225 can be used to encapsulate electronic assemblies and PCBs subject to an operating temperature range of -40 to +180°C; ER2225 will even tolerate short excursions of up to 210°C. The resin shows good thermal conductivity (1.1W/mK), making it suitable for industrial applications requiring good heat transfer across a wide temperature range. While ER2225 does contain fillers, in tests the resin shows excellent flow around components and is easy to process in a fast moving production environment.

The new polyurethane and epoxy resins are all initially available in handy 250g pack and 5kg kit sizes to meet every need, from prototyping and product development to full production.

Visitors to Productronica 2017 are invited to meet the Electrolube team in Hall A4 of the Messe München, Booth 466. During the course of the show, Electrolube will be hosting live selective coating demonstrations on a PVA system. Visitors are welcome to put their process and application requirements to the team, who will be happy to discuss solutions that will really make a difference.
