EPOMIN™ HM-2000 Polyethyleneimine (PEI)
- Main Applications
Laminate anchor coating agents for paper, cloth, OPP and PET film, Heavy metal chelating agents, Metal plating additives, Foam retainers for fire extinguishers, Immobilized enzymes, Adhesives (for PVC sol flocculants, Epoxy resin crosslinkers), Ink adhesion enhancer, Water treatment (as coagulants)
Basic Information
High molecular weight type of polyethyleneimine
HM-2000 a high molecular weight type of polyethyleneimine (PEI), has been added to the EPOMIN™ SP series product lineup.
HM-2000 has a high molecular weight but little diluent water. So it is fast drying, and the formulation can be freely improved.
