Product Name: Exothane 9, PEG 400 Extended Urethane Dimethacrylate
Synonyms: PEG400 UDMA, Extended UDMA
CAS#: 72869-86-4
INCI: Di-HEMA Trimethylhexyl Dicarbamate

Our extended UDMA is commonly used in photo-cure applications. The PEG 400 backbone creates a flexible polymer upon curing. Adding X-726-0000 has been shown to increase the fracture toughness of UDMA. X-726-0000 also has very low viscosity and low color.
