Synthesis of new silane coupling agents with a trimellitic anhydride group and application as primers for ceramics and alloys.

摘要: With a view to improving the bond strength of resin dental ceramics and alloys, new silane coupling agents, namely 4-trichlorosilylpropyl- 4-trimethoxysilylpropyl-trimellitic anhydride (4-CSTA 4-MSTA, respectively), were synthesized. In addition, mixtures 4-CSTA with 3-methacryloyloxypropyltrimethoxysilane (3-MPS) 4-MSTA 3-MPS used as primers for adhesion poly (methyl methacrylate) glass, silver-palladium-gold alloy (Ag-Pd alloy), cobalt-chromium (Co-Cr alloy). The tensile strengths glass using 4-CSTA+3-MPS 4-MSTA+3-MPS 28.5 +/- 5.3 23.9 8.1 MPa respectively. metal 14.8 Ag-Pd 24.7 7.2 Co-Cr alloy. light these results obtained, it seemed that mixture was an effective primer both metals ceramics.
