General description

Urethane acrylate methacrylate resin (UDMA) is formed by reacting 2,4,4-trimethylhexamethylene diisocyanate and 2-hydroxyethyl methacrylate (HEMA). It is mainly used as a dental resin with a higher water uptake than that of bisphenol A-glycidyl methacrylate (Bis-GMA).[1]

Application

UDMA may be combined with triethylene glycol dimethacrylate (TEGDMA) as a resin to develop composite blocks, which can be used for dental computer aided design applications.[2] It may also be used to decrease the water sorption and increase the mechanical strength of the dental composites.[3]
