Wondering if anyone can help me identify a suitable filler to match the black material surrounding these leds.
It has a spongy consistency … you can press your thumbnail right through it easily … far softer than normal silicon.
I cut a section out and it is really easy to tear up, it has no real strength at all.
I assume its role is to weatherproof the leds, keep them aligned and provide a consistent matt background to minimise reflection.
The panel is from a sign … over 3000 leds … and ~120 need replacing. It is behind an outer perspex screen so weatherproofing is not quite as serious.
Thanks for any help.
