Lupasol^® polyethylenimeines are branched, multi-functional, cationic polymers.  Due to the polycationic nature of branched polyethylenimine can be used in a wide range of applications. Lupasol^® polymers will adsorb tightly to negatively charged surfaces.  This makes Lupasol^® polyethylenimines incredibly efficient as an adhesion promoter, primer, or tie-layer for dissimilar materials.  Additionally, the cationic nature of Lupasol^® Polyethylenimines makes them effective at dispersing cationic pigments.  Pigments dispersed with Lupasol^® are easier to process and yield higher color strength.  Finally, Lupasol^® can be used to flocculate and separate negatively charged contaminants and heavy metals from water and waste water sludge.
