Elvacite™ 4347 is a thermoplastic acrylic resin that is designed for use in coating, ink, and adhesive formulations that require good adhesion to bare metal surfaces. It is available as a non-dusting bead that is soluble in common esters, ketones, and aromatics. Solutions containing Elvacite™ 4347 will produce clear films that adhere well to aluminum, brass, copper, steel, bronze, and various other metals. The films have excellent flexibility, toughness, and outdoor durability.
