I think the catalyst presence likely represents a cure problem to begin with. Often in colder temperatures, a shop will often boost catalyst levels too high in an attempt to get a cure rather than wait to get the shop and molds up to proper working temperature. The additional catalyst doesn't react and remains trapped in the laminate.
question, when digging out blisters, why do they have catalist acid in them?
And that's a classic failure. And it isn't actually a catalyst anyway, it is an initiator but I don't think we'll ever see the terminology corrected.
Sssssshhhhh, you're just gonna confuse people
