Description

Coace® K2D is a chemical modified polyethylene , which offers excellent adhesion to foil, paper and other polar substrates.

Coace® K2D is a type of polyethylene that has been chemically modified to enhance its adhesive properties, particularly to polar substrates such as foil and paper. This modification of the polyethylene structure alters its surface energy, allowing it to form strong bonds with polar materials.
