50% aqueous solution of polyethylenimine with a molecular weight around 1,300.
Lupasol® G 20, a 50% aqueous solution, is a multi-functional cationic polyethyleneimine (PEI) with a branched polymer structure. The unique properties of Lupasols allow them to promote adhesion, disperse fillers and pigments, flocculate suspended solids, enhance and modify surface characteristics, protect materials after surface modification and bind unwanted materials.
