Elvacite® 4149

Elvacite® 4149 is a low molecular weight methyl methacrylate / n-butyl methacylate copolymer that is useful in metal lacquers and heat seal coatings.
Product Overview

Elvacite® 4149 is a thermoplastic solid bead acrylic resin that is useful in solvent based lacquers, inks, and adhesives. Elvacite® 4149 is soluble in ketones, esters, and glycol ethers. It is unique in from other acrylic resins in that it will form clear solutions in acetone for VOC exempt formulations. Elvacite® 4149 is often used as a binder and film former in coatings and inks that require excellent durability to UV and heat. When used as a binder it will form films with remarkable clarity and gloss.
