Phil:

  It is actually possible for a soldermask to be a bit of all those classes, however, most LPI soldermasks are predominantly acrylics.  This is what makes them strippable.

  hi,

i'd like to know the class(es) of organic compounds that lpi soldermasks
fall into. would/could they classified as urethane, acrylic, epoxy, or
other? we need to identify the class(es) to our customer and i haven't
had much luck. i'm sure it depends on the vendor, so if i get reponses
that indicate they could fall into several classes, i'd like to know
what they all are.

thanks,

phil
