Do we have to use silicone in the installations? What does it protect from? What if we did not use it?

Answer:

For the busbar area of PDLC film, we suggest using transparent tape or silicone sealant to seal it, to isolate it from water or other liquid, then it can work well for a long time. However, in a dry and clean environment, even if you don’t use it, it doesn’t have a significant impact.
