Hello everyone.

I have heard that sodium is a proper chemical for higher Tg resin like BT.
But I'm using potassium permanganate system now.
Is it possible to etch BT resin if I exchange potassium permanganate into
sodium permanganate? And what's the relationship between Tg and etching process?
If anyone has experienced with sodium type or has a good reference,
please let me know.

Best regards
Taegon Lee
