Health concerns regarding polyester resin handling



I'm an artist and want to do a large piece with transparent polyester resin. First of all I want to know how safe is it to work with this resin. Does breathing the vapor of the resin have serious health hazards?

Polyester resin, as well as the hardener are noxious chemicals. If you have to use them, do it in a well ventilated area, wear eye and hand protection and adequate clothing. If possible, use epoxy or acrylic resins instead of polyester.

What Alfonso said is essentially correct.

From what I've seen of largish FRP manufacturing operations, ventilation is fairly important, sometimes people use Protective Gloves [linked by editor to product info at Amazon], sometimes eye protection, most often they don't.

And an art piece would be far easier for you to do using Polyester which, anyhow, costs less than epoxy. Get some Acetone [linked by editor to product info at Amazon], too, as that will help you to clean up things!

When you say 'large piece' do you really mean it? Why? Because if you get a whole drum of resin you'd need catalyst and maybe promotor .. in which case NEVER mix the two together and store separately.
