Araldite 2028-1: a bright idea for LED encapsulation

ARALDITE® 2028-1, make your design stand out by keeping bond lines invisible.

LED potting requires great care in the choice of the encapsulation product : the chosen product must be perfect transparent, in order to allow the LEDs to display multiple colors, and it must keep its optical properties for several years.

Here is an example of potting of touch pad keys : the Araldite 2028-1 plays multiple roles here .This polyurethane must ensure 100% water- and dust-tight LED potting, but it must also ensure a perfect and homogeneous light diffusion.

Moreover, the low viscosity of Araldite 2028-1 allows bubble-free encapsulation, without the need for a vacuum process. Finally, its ease of use and its quick setting time allow you to maintain sustained production rates.
