“…(2) Surface adsorbed water was removed by heating the samples at 110 8C for 2 h under vacuum. Two percent AEAPS solution in ethanol was prepared in argon ambient [4,5]. To maintain orientation of NH 2 group of AEAPS away from the surface, the pH of the silane solution was optimized to 3.7 by adding acetic acid.…”

The aim of this study was to evaluate the reactions of silanes prior to attaching the composite to titanium and evaluate these silanes as coupling agents. Veneered titanium may be used as a prosthetic material.Methods. Two silane solutions, a mixture of both g-methacryloxypropyltrimethoxysilane and vinyltriisopropoxysilane, and tris(3-trimethoxysilylpropyl)isocyanurate were prepared as 2 wt% in two different (95% 2-propanol and 90% acetone) solutions. A control, 2 wt% g-methacryloxypropyltrimethoxysilane was prepared in both solutions. These six silane solutions were applied onto flat titanium surfaces. The samples ðN ¼ 250Þ were divided into two main groups: air-dried (room temperature) and heat cured for 1 h at 110 8C. Sinfony w veneering composite was applied and light-cured on the titanium. The control group was non-silanized. The specimens were assigned to two subgroups: not thermocycled, and thermocycled (5000 cycles, 5-55 8C). Shear bond strength of the composite was tested at a crosshead speed of 1.0 mm min 21 . Fresh silane solution hydrolysis, and condensation reaction on titanium surface were monitored by FTIR spectrometry.Results. Dry samples could be successfully tested, while thermocycling after 3700 cycles had gradually de-bonded the composite from the silanized titanium substrate. For dry samples, statistical analysis (ANOVA) showed that solvent and silane significantly affected the shear bond strength. The silane mixture in 2-propanol reacted at room temperature yielded 11.3 MPa (Standard deviation, SD, 3.6 MPa) and on the other hand, tris(3-trimethoxysilylpropyl)isocyanurate in 2-propanol yielded 10.7 MPa (SD 8.0 MPa) and g-methacryloxypropyltrimethoxysilane 20.4 MPa (SD 12.2 MPa). Non-silanized samples yielded 4.8 MPa (SD 2.1 MPa).Significance. In all solvents used, silanes reacted chemically with the titanium surface and covalent Si-O -Ti -and -Si-O -Si-bonds were evident.

“…The remaining silanol groups may condense with adjacent silanols to form a siloxane layer (Si-O-Si) or remain partly uncondensed at the surface. The organofunctional group 'methacrylates' exhibits the best wet strength with polyester and the functional group -(CH 2 ) 3 Si(OMe) 3 of methacrylate additive exhibits the highest flexural strength of polyester glass laminates [3]. The functional group -(CH 2 ) 3 Si(OMe) 3 reacts with hydroxylated SiC surfaces through hydrogen bonding and through covalent siloxane (Si-O-Si) bonds [4].…”

The effect of dispersants on particle dispersion and flexural properties of SiC/vinyl ester nanocomposites was studied by factorial and response surface designs. The results show that the coupling agent 'gamma-methacryloxy propyl trimethoxy silane (MPS)' has no adverse side effect on the flexural properties as illustrated by the good correlation between maximizing the flexural strength and minimizing the agglomerates. However, the dispersant 'BYK-W 966' has a slight adverse side effect on the flexural properties although it improves dispersion at higher dosage. With an optimal dosage of MPS and W966, a small amount of SiC in 0.5 wt% results in 8% increase in strength and 14% increase in modulus. The flushing operation using the dispersant '1-octanol/decane' achieves an excellent SiC dispersion but it does not result in improved flexural properties. This confirmed that a better state of nanoparticle dispersion does not necessarily lead to improved flexural properties. A good dispersion coupling with a strong filler/matrix interfacial bonding is the key to obtain enhanced flexural properties.
