Further reading......I just found on Faceache!
Hi ......I have recently bought some acrylic blanks before really knowing the differences between acrylic,polyester and epoxy. I was a bit startled to find this article
Acrylic resin (but not acrylic emulsion, which is the basis of acrylic paint) is a thermoplastic, which means it is one of a group of plastics which can be heated and manipulated repeatedly, whereas polyester resin and epoxy are thermosetting plastics, which use heat or a catalyst to solidify into a solid mass that won’t melt down. Acrylic is mixed from acrylic polymer, a dry powder, a methyl methacrylate monomer, a thin liquid, and usually an organic peroxide hardener of some sort. If pieces of any size are contemplated, an autoclave or hydraulic press is necessary for reducing air-bubbles and counteracting the internal stresses created by the strongly exothermic reaction. The dust is toxic, as is the monomer and its vapors. And the organic peroxides are especially poisonous, some of them being explosive and others causing instant blindness if they get in ones eyes.
Am I right in thinking that once the resin has cured these issues don't apply, or is the dust produced from turning and sanding still toxic ?
I don't know any of the validity but a good point to research from
