Hi Guys,
<div class=""><br class="">
</div>
<div class="">I have no experience with ZEP, but the data sheet suggest a critical dose of ~35 uC/cm2, approximately 1/10 of PMMA. What are the problems with ZEP and under what conditions is it worth the cost? Does it last forever in storage like PMMA?</div>

<div class="">Thanks,<br class="">
