More Information
Summary:A primer composition has been discovered which improves bonding of dentin and filler resin. The primer composition disclosed in the present invention contains, in weight ratio of 20:1 to 5:1, of 2-hydroxyethyl methacrylate and the esterification product of polyvinyl alcohol and acryloyl chloride. The weight average molecular weight of polyvinyl alcohol ranges from 60,000 to 85,000 with residual acetyl content is less than 10%. The esterification of OH group in polyvinyl alcohol ranges from 5 to 40 mole percent. The present invention does not contain glutaraldehyde, but provides greater bonding strength.
