LUPASOL PR8515

Lupasol® PR 8515 is a polyethylene imine that functions as an adhesion promoter in adhesives, a crosslinker and hardener in epoxy and polyurethane adhesives, aids in the complexation of heavy metal ions, facilitates the easier dispersion of pigments and increases color strength, and enables the immobilization of proteins on inorganic materials. It is also used as a primer to improve adhesion to the substrate for coatings.
