Elvacite® 2045

Elvacite® 2045 is an iso-butyl methacrylate polymer that is used in coatings for solvent sensitive substrates, plastic topcoats, and printing inks.
Product Overview
Elvacite® 2045 is a high molecular weight, solid bead acrylic resin with broad solubility and a relatively low glass transition temperature (Tg).
It is highly soluble and is used in coating applications where the substrate can't tolerate the use of powerful solvents.
Elvacite® 2045 provides a good balance of flexibility and toughness.
It is commonly used in protective top coats for metalized plastic films and as a binder in printing inks being printed onto flexible substrates.
Additionally, Elvacite® 2045 burns out very clean and works well in applications that require a temporary binder to improve green strength.
