Description

Lencolo 4051 is a phosphate-ester grafted polymer containing highly reactive phosphate-carboxyl groups. It effectively promotes adhesion on metals, plastics, and other substrates. Its high intermolecular polarity significantly enhances adhesion on low-polarity surfaces. With excellent compatibility and outstanding adhesion-promoting performance, it is widely used in UV-curable coatings, vacuum metallized primers, plastic topcoats, 3C spray coatings, inks, laminating adhesives, as well as epoxy, polyurethane, acrylic, and nitrocellulose-based coatings.
