Similar to Elvacite® 2016 but yields clear solutions in acetone. Elvacite® 4149 is a low molecular weight methyl methacrylate / n-butyl methacrylate copolymer. Elvacite® 4149 works well in clear, translucent or pigmented metal lacquers. It is a quick dissolving, low viscosity resin for coatings, inks, and adhesives.
Elvacite® thermoplastic acrylic resin copolymers or polymers are seen in solvent-applied high-quality coatings. Due to the wide range of attributes, Elvacite® is suitable for numerous applications.
