Lupasol® G 20 is a water-free polyethylene imine that functions as an adhesion promoter in adhesives, a crosslinker and hardener in epoxy and polyurethane adhesives, and aids in the complexation of heavy metal ions. It is used as a primer for improved adhesion to the substrate for coatings, facilitates the easier dispersion of pigments and provides higher color strength, and enables the immobilization of proteins on inorganic materials.
