Modified Polyethyleneimine 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
1) Octadecyl isocyanate modified polyethyleneimine
RP-20 is the modified polyethyleneimine reacted with octadecyl isocyanate. RP-20 has two functionalities: being in the hydrophilic amino group, and being lipophilic (hydrophobic: C18).By using these functions, RP-20 shows an exceptional effect as a rear-side release agent of pressure-sensitive adhesive tape which base materials are polyester, polyethylene, polypropylene, cellophane, and paper, etc.
