Electrolube Australasia supplied a silicone encapsulation compound to an LED lighting manufacturer to help them address environmental challenges in their installations.

Modern commercial lighting systems not only have to meet a variety of standards and specifications, but must also ensure robust construction and adequate environmental protection in an aesthetic package.

The manufacturer of LED lighting systems sought Electrolube’s advice on a new project where it was supplying luminaires for use in a range of commercial buildings and hotel lobbies. The location and design of these buildings presented certain challenges in terms of environmental protection, since the lighting units needed to be resistant to UV light and outside weather conditions. Additionally, since the lighting units were likely to be visible even when switched off, they needed to have a pleasing appearance.

The LED lighting manufacturer’s key requirement was to protect the LED units from corrosion without compromising their appearance. A protective material was sought for the LEDs that would provide the required environmental protection while preserving the units’ high quality finish.

Following an appraisal of its customer’s needs, Electrolube recommended its silicone resin SC3001 for the application as it offered excellent clarity as well as good protection against harsh weather conditions.

Electrolube’s SC3001 is an optically clear, RoHS-2 compliant (2011/65/EU), flexible, two-part encapsulation compound particularly suited for use in the LED lighting industry where optical clarity is vital. The new optically clear silicone potting compound is very easily applied in thin film due to its low viscosity and moisture cure nature.

In addition to supplying the appropriate encapsulation material, Electrolube also offered advice about potting methods and the selection of appropriate production equipment since care needed to be taken to avoid the introduction of excessive amounts of air when mixing the SC3001 components. Electrolube referred its customer to suppliers of specialist automatic mixing equipment, which not only mixed both resin and hardener accurately in the correct ratio but also achieved this without introducing air.
