Polyethylenimine CAS 25987-06-8

Ethylenediamine terminated polyethyleneimine (also known as branched polyethyleneimine, CAS 25987-06-8) is a water-soluble polymer that appears as a colorless to pale yellow viscous liquid at room temperature. Its molecular chain contains a large number of primary, secondary, and tertiary amine groups, endowing it with extremely high cation density and strong adsorption properties.
This product, with its high reactivity and adhesion, is mainly used as a primary brightener and grain refining agent in alkaline galvanizing to enhance the performance of the coating; It is also widely used in the fields of wet strength agents, water treatment flocculants, ink coatings, and adhesives in the paper industry.
