CP 515-2-40% is a solution grade polyolefin adhesion promoter that is used as an additive to coatings, inks, and adhesion to increase adhesion to plastic.
CP 515-2 is a highly compatible chlorinated polyolefin polymer that is useful as an additive to coating, ink, and adhesive formulations that are to be applied to untreated, low surface energy plastics. CP 515-2-40% Aromatic 100 is the solution grade of this polymer at 40% solids in aromatic 100. CP 515-2-40% should be added to coatings and inks at 5 parts CP 515-2 polymer to every 100 parts binder solids by weight in order to maximize adhesion benefits. When used in a formulation CP 515-2 shows little to no effect on color and provides clear films upon drying.
