Lupasol Polyethylenimines are branched spherical polymeric amines. Due to their high charge density they adsorb tightly on negatively charged surfaces. This mode of action can be applied to a huge variety of materials such as mineral aggregate, paper & metal. Polyethyleneimines act as adhesion promotor for a variety of Binders and Substrates.
LUPASOL WF EM is a highly versatile polyethyleneimine that has found extensive use in several industries. It is commonly used as an adhesion promoter in adhesives and car tires and for the complexation of heavy metal ions. Besides, it is also used in printing ink and plastic modification, as well as pigment manufacture. It can even immobilize proteins in inorganic materials.
