Case Study

Application: Potting LEDs in Electronic Keypads with ARALDITE® 2028-1 Adhesive

Achieve water- and dust-tight transparent potting for harsh environmental conditions.

The Challenge

Efficiently potting LEDs behind touch pad keys that will be exposed to tough conditions.

The Solution

In customer trials, the ARALDITE® 2028-1 adhesive has proven to be the best adhesive able to ensure 100% water- and dust-tight LED pottings in PCBs.

With no need for a vacuum process, this non-foaming adhesive is easy to apply, enabling a fast and highly efficient production cycle. The result is an end-product with perfect transparency, allowing LEDs to display multiple colors.
