Glass Stripper Overview
An amine-based stripper that enables fast and complete D/F stripping. Suitable for stripping on glass
substrates,
with excellent stripping performance for D/F crosslinked through exposure and
Post-Exposure Bake (PEB).
It can be used as-is (neat) in the bath, making make-up replenishment also easy.
