NazDar has a pretty good range of ADE, (air dry epoxy) inks but their Pantone Matching Guide book is labeled for "conventional" inks and many of the color numbers in the guide are not available in the ADE pallet.
You should be able to come close to your customers colors but tell them outright that you cannot match Pantone colors perfectly. That's just the way it is with most screen inks.
May I ask what your need is for epoxy inks? About the only time I use them is for imprinting powder coated control panels. White, Black and Reflex Blue pretty much cover my needs. Are you sure you can't get away with catalyzing the 9700 all purpose inks? That series is totally covered in the Pantone Guide.
