AKA: Film-forming polymer
Synthetic
Not Clean
OriginDerived from polyethylene glycol (PEG) polymers and alicyclic isocyanurate compounds combined through synthetic chemistry. Synthesized by reacting methoxy PEG chains with HDI isocyanurate trimers via crosslinking polymerization.
ethoxy PEG-17/Methoxy PEG-11/HDI Isocyanurate Trimer Crosspolymer is a copolymer of methoxy PEG-17, methoxy PEG-11 and hexamethylene diisocyanate (HDI) trimer in which the free isocyanate groups are crosslinked by water to form urea linkages.
