I just bought a mechanical keyboard and in the interest of keeping it quiet have found that some people recommend pouring liquid silicone into the keyboard case to form a silicone sound dampener that fits below the keyboard PCB.
I was wondering if silicone is a safe material to use next to/in contact with a PCB. I'm wondering if it will short out the contacts on the board? I'm also wondering if it will be corrosive?
Here's an example of someone making a silicone damper How to Make a Silicone Mold
