[labnetwork] Alternative distributor for SPR 955?

[Howard Northfield]

I am pretty much now used to getting materials only months from expiry from all sources.

Subject: [labnetwork] Alternative distributor for SPR 955?

Attention : courriel externe | external email

Dear Labnetwork,

Does anyone purchase SPR 955 (or any other Shipley/Dupont products) from a distributor other than Kayaku?  We have had numerous issues with different materials.  In this case, we need to either find a different distributor or begin qualifying another resist, probably both.  The current issue is that we purchased a gallon of SPR955 which was “in stock.”  It arrived last week with an expiration date of 7/8/23.  Kayaku’s response was that they were required to ship what they had on hand first and would ask for an extension to the expiration date from the manufacturer.  I am still hoping for a better response and solution than that but need to find an alternative in the meantime.



If anyone works with a different distributor for Shipley resists, I’d love to hear your experience.  I’ll share the final solution from Kayaku and summarize any responses for alternatives.



Thank you,

Aimee Bross Price
