Gene Delivery (Transfection)
Polyethyleneimine (PEI) has important uses in biotechnology and pharmaceutical research as a transfection agent. It helps deliver genetic material (DNA or RNA) into cells by forming complexes with the negatively charged nucleic acids, facilitating their entry into cells.
Water Treatment
Due to its strong positive charge, PEI is a flocculant in wastewater treatment.
Adhesives and Coatings
PEI is used in the production of adhesives, paints, and coatings due to its strong adhesive properties and chemical resistance.
Paper and Textile Industries
In paper manufacturing, PEI improves the retention of fillers and increases paper strength. In textiles, it can enhance dye fixation and durability.
Corrosion Inhibitor
In coatings, Polyethyleneimine can protect metal surfaces from corrosion, especially in industrial settings.
