[labnetwork] SU-8 distributors (Kayaku ending SU-8 2000 series early 2025)

[Eric Johnston]

Hi Ben

We have been working with Kem Lab recently. They offer their version of SU8
and Jeremy Golden has been very helpful.

My understanding is that the surfactants that have been used in these types
of resist are on the verge of being banned, as they are the same or similar
to PFAS. Please, anyone feel free to correct me on this!

Regarding your specific question, we have experience with SU8 3000, which
offers better adhesion at the cost of slightly poorer resolution.

Best

Eric
