I’ve been using Airtac spray for years with epoxy products and never noticed a residue left behind once the part is cured/released. Lately I’ve been using it with polyester resins and I have a residue on the mold surface after releasing parts. The parts have been curing fine and seem to have a very light tackiness that washes off pretty easily.
Anyone have similar experience with airtac and polyesters? Is there a better option to placing reinforcements for infusion that won’t have these compatibility issues?
Thanks!
