| abstract |
Two component adhesive formulations are described that can be mixed to form compositions containing a curable liquid resin binder and filler. The liquid resin binder comprises from about 1% to about 60% of a lower alkoxy, lower alkyl methacrylate comprising methoxyethyl methacrylate, and from about 40% to about 99% of a polyunsaturated agent selected from the group consisting of aliphatic or aromatic diacrylates or dimethacrylates or mixtures thereof, the percentages being by weight based on the liquid resin binder. The filler forms up to 80% by weight of the adhesive composition and consists of finely divided inorganic filler, finely divided organic filler that may be soluble in the liquid resin binder, and mixtures thereof. The preferred compositions are useful as orthodontic adhesives and contain from about 10% to about 50% by weight of the liquid resin binder of methoxyethyl methacrylate. |
