Overview
Lupasol® PS is an aqueous solution of a high molecular weight polyethylenimine. The polyethylenimine polymer in Lupasol® PS carries a very high cationic charge density that makes this product useful as an adhesion promoter, cross linker, dispersion aid, and flocculant. Lupasol® PS is soluble in water as well as most polar solvents and can be diluted easily to your desired working concentration. Lupasol® PS is available commercially as a clear to pale yellow, viscous liquid in 55 gallon drums.

Applications
Lupasol® PS is most commonly used to improve adhesion of inks, coatings, and adhesives to low surface energy substrates.
Lupasol® PS can be added directly to alkaline formulations or it can be used as pretreatment / primer to increase adhesion.
Lupasol® PS is often used in combination with polyvinyl alcohol, polyvinylbutryral, polyvinyl acetate, and styrene copolymers as a cross linker to improve cohesion of tape and label pressure sensitive adhesives.
Lupasol® PS is an excellent flocculant and chelating agent for negatively charged contaminants and heavy metals.
It is used as a flocculant in both
water pretreatment and household detergent applications.
