Liquid acrylic is methyl methacrylate, sometimes referred to as methyl methacrylate monomer (acrylic is poly methyl methacrylate, PMMA). But this is fairly nasty stuff and I think toy store casting resin is polyester (polyester/styrene, still somewhat nasty but not quite as volatile). Try a search for casting resin.

Dear Glen Walpert and Uncle Al,
Menny thanks for your answers.
I will go look for these "nasty" products. :-)
Best regards Søren Momsen

In my experience with acrylics, it is the little guy that has all the safety problems. Like the dental lab blowing fumes out an apartment window causing neighborhood problems with smell or the thermoformer out in the country that cannot protect his workers from fumes. You can smell MMA at less than 1 ppm while 50 ppm is safe. Just consider safety and neighbors when handling. Frank
