[labnetwork] Alternative distributor for SPR 955?

[Price, Aimee]

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
