Premixed ready made inks such as Speedball or Jacquard, and ink systems for self mixing using acrylic paint and a custom silkscreen printing medium (see below). There are two kinds of acrylic based ink system that are widely used.
Printing with acrylics on a variety of substrates: vinyl saddles (left) Nitrogen-containing plastics such as nylon and polyurethanes typically release hydrogen cyanide chlorine-containing materials such as polyvinyl chloride typically release hydrogen chloride and polystyrene, polyesters such as polycarbonate, nylons, and polyurethanes may be more likely to degrade into their original monomers." Monomers and other by-products are released through various modes of degradation such as heat. This inherent instability contributes to the release of residual monomers, plasticizers, ame retardants, solvents, and other additives as polymers degrade.īased on the toxicity of monomers, research has defined the most hazardous polymer families as polyurethanes, polyacrylonitriles, polyvinyl chloride, epoxy resins, and styrenic copolymers. These highly reactive monomers form stable bonds in polymers through polymerization, though the chemical r eactions are never quite complete. "Plastic polymers are created from monomers almost exclusively derived from crude oil with far-reaching impacts on the health of humans and the environment. Inherent Instability in Monomers and Polymers (from: A pilot study to evaluate VOCs outgassed in polymer filaments, Shari Cheves, 2014)
