Overview
Lupasol® G 20 WF, is an anhydrous, low molecular weight, polyethyleneimine (PEI) with a branched polymer structure. Lupasol® G 20 WF carries a high cationic charge density that makes it multi-functional and highly efficient at promoting adhesion, crosslinking polymers, flocculating contaminants, and dispersing pigments. It is available commercially as a clear to pale yellow, viscous liquid in 55 gallon drums. Lupasol® G 20 WF is soluble in water and other polar solvents and can be easily diluted to your target working concentration. Due to the cationic nature of the polymer, Lupasol® G 20 WF is recommended for use in alkaline, nonionic and cationic formulations.
