Our EE cleanroom is looking to reduce the amount of photoresist we have to dispose of due to its age. We have, over the past 10-12 year, been receiving a generous donation of HPR-504 positive photoresist, developer and stripper all in gallon containers. The developer and stripper are used in its donated quantities, however, the photoresist we use less than a pint in a 2 year span. This leaves us over ¾ of a gallon to dispose of as chemical waste which negates the benefit of the donation. Our EHS would like us to see it there is a way to get the resist in smaller quantity to reduce the cost of disposal.
I would appreciate a source where I could get smaller amounts of the photo resist.
Thanks
