Acrylic resins are particularly durable synthetic resins and are used in various adhesives, paints and coatings. Before curing, they are present as monomers in liquid form and therefore not nanoparticles. Due to the wide range of possible applications, they may contain various additives e.g. consisting of nanoparticles. However, there is no health risk associated to nanoparticles containing acrylic resins as the nanoparticles are firmly bound in both the liquid and cured form and cannot be released into the environment.
