most widely used polyester resin

just wondering what the most popular polyester resin is. and the most durable.

Well, most used is probably the resin that finishes out with maximum clarity or lack of color tint. Clear and durable are not necessarily one in the same. Vinyl esters have been discussed widely here in past threads for providing a high strength to weight ratio lamination, at the expense of clarity. Pigment solves that problem nicely. Silmar polyester resins are widely used for production due to it availabilty and clear finish. Epoxy laminations are common today as well and Greg Loehr’s product (Resin Research)is very clear. Hope that helps. Tom S.
