Abstract

A fire-retardant potting compound for a backlit device is disclosed. The fire-retarding potting compound includes a white resin, an Aluminum Trihydroxide powder, and a hardener mixed together. The fire-retardant potting compound may be applied to a panel of a backlit device, in between a light source and one or more transmissive features of the panel.

Description

Background technique [0001] Backlight devices may contain potting compounds that protect components of the device (e.g., electrical components) from liquids, dust, shock, vibration, and the like. Potting compounds can also be used to obtain a more uniform light dispersion. However, some potting compound formulations are more likely to trap heat and / or catch fire. Therefore, there is a need for potting compound formulations that meet thermal conductivity and flame retardancy requirements for specific applications. For example, a potting compound for a backlight unit in an aircraft cabin may need to meet the US Federal Aviation Regulations (FAR) 25.8.53 test standard. Contents of the invention [0002] A flame retardant potting compound for a backlight device is disclosed. In one or more embodiments, the flame retardant potting compound comprises a white resin, aluminum hydroxide powder, and a hardener mixed together. The flame retardant potting compound can be applied to ...
