Lupasol P, is a high-molecular weight, branched polyethyleneimine (PEI) polymer supplied as a 50% aqueous solution. Known for its high cationic charge density, it functions as an excellent adhesion promoter, flocculant, and dispersing agent. It's infinitely soluble in water and polar solvents. Key applications include improving adhesion in water-based primers for packaging films, textiles, and metals, as well as in coatings and ink formulations, and for complexing heavy metal ions in water treatment.
