Claims10
An adhesive composition comprising an etchant for a hard tissue surface, at least one multifunctional (meth)acrylate monomer with a functionality greater than 4, wherein the monomer is selected from the group consisting of acrylates and methacrylates derived from a hyperbranched dendritic polyester polyol, and water, wherein the adhesive composition is a water-in-oil emulsion.
A dental adhesive composition, comprising:
- (a) 5-25 wt % of a multifunctional (meth)acrylate monomer with a functionality greater than 4, wherein the monomer is derived from a hyperbranched dendritic polyester polyol;
- (b) 10-25 wt % water;
- (c) 0-25 wt % of a co-solvent selected from the group consisting of ethyl alcohol, ethyl acetate, and isopropanol;
- and
- (d) 5-11 wt % of an etchant for at least one of dentin and enamel,
- wherein the dental adhesive composition is a microemulsion.
