- INORGANIC DENTAL FILLERS INCLUDING A SILANE TREATED SURFACE
-
The present disclosure provides an inorganic dental filler including a surface treated with at least one silane. Exemplary silanes described in the present disclosure for the suface treatment of the inorganic filler include silanes of Formula I and/or Formula II: (RSi)-(CR1R2)n-(NH-C(O)-O-CH2-CH2)q-N(R5)-C(O)-NH-(CH2-CH2-O)t-CR3R4-CH2-(A) Formula I (RSi)-(CR1R2)n-NH-C(O)-O-CR3R4-(L)q-CH2-(A) Formula II, wherein: RSi is a silane-containing group of the formula -Si(Yp)(R6)3-p, wherein Y is a hydrolysable group, R6 is a monovalent alkyl or aryl group, and p is 1, 2, or 3. Methods of making and using the surface treated inorganic dental fillers are also disclosed.

- Monofunctional acrylate monomer containing siloxane structure and preparation method of monofunctional acrylate monomer
-
The invention discloses a monofunctional acrylate monomer containing a siloxane structure and a preparation method of the monofunctional acrylate monomer, belongs to the field of preparation of functional photopolymerization monomer. The monofunctional acrylate monomer containing the siloxane structure provided by the invention is prepared by using a silane coupling agent containing amino group and isocyanate group to react with different substances. The prepared monomer contains a hydrolyzable silicone structure and a photopolymerizable acrylate structure, and can be added to a formulation of a photo-curable product to enhance adhesion force to the surface of a hydroxyl-rich substrate (such as oxidation-treated glass); the prepared monomer also contains an amide bond, which improves the flexibility of a photocurable film.
