Good morning all,

Earlier this morning, not yet fully awake, I indicated:   "Urethane
coatings are pretty good at moisture inhibition and solder masks
are a combination of acrylics and urethanes."

Mike Barmuta correctly pointed out that solder masks are blends of acrylic
and epoxy, except for some older screened masks which are pure epoxy.  Not
urethanes.  Thanks for the catch Mike.
