Fluorinated urethane dimethacrylate with carboxylic units (UF-DMA) was proposed as co-monomer in dental adhesives.
UF-DMA exhibits good photoreactivity in mixture with commercial dental monomers.
Water sorption/solubility and diffusion coefficient depend on the amount of UF-DMA.
The infiltration of adhesive mixture into the dentin tubules was evidenced by SEM.
