Product Details
Introduction
Polyethyleneimine (PEI) is a cationic polymer formed by the polymerization of aziridine under certain conditions. Each PEI monomer contains two Cs and one N. The ratio of the number of primary amines, secondary amines and tertiary amines contained in its molecular chain is 1:2:1.
1. It can form intermolecular forces such as hydrogen bonds on the surface of coatings, fibers, electroplating, and metals to improve the adhesion of the surface layer, especially for difficult-to-attach substrates.
2. Papermaking, paper processing, and petroleum fields; neutralize anionic charged substances to improve the fixation effect and retention rate, exert resin control and white water purification effects, and promote the dispersion and fixation of ketene dimers; PEI has particularly excellent wet strength after adding other substances, and is widely used as a plugging agent in paper processing and petroleum fields;
