Lupasol® FG is a polyethylene imine that serves as an adhesion promoter in adhesives, a crosslinker and hardener in epoxy and polyurethane adhesives, and is used for the complexation of heavy metal ions. It can also be used as a primer for improved adhesion of coatings to the substrate, for easier dispersion of pigments and higher color strength, and for the immobilization of proteins on inorganic materials.
