“…Washing with a polar solvent, such as ethanol, removes the physically deposited but not the chemically adsorbed monomers [21]. The chemically adsorbed silane-coupling monomers will serve as receptors for co-polymerization with other methacrylates, such as bisphenol A-glycidyl methacrylate (Bis-GMA), diurethane dimethacrylate (UDMA), etc., commonly being present in adhesives and cements [22]. Separate silanization as part of SAP_CP resulted in high surface hydrophobicity that was not significantly different from that measured upon the application of the silane-containing self-adhesive composite cement SAU.…”

Objective: Hydrofluoric-acid etching followed by silanization is a routine clinical protocol for durable bonding to glass ceramics. Simplifying ceramic-bonding procedures, new technological developments involve the inclusion of a silane coupling agent in a self-adhesive composite cement. To investigate the effectiveness of the incorporated silane coupling agent, shear bond strength (SB) to ceramic and dentin, contact angle of water (CA), transmission electron microscopy (TEM), X-ray diffraction (XRD) and 29 Si nuclear magnetic resonance (NMR) assessments were correlatively conducted.Materials and Methods: SB to glass ceramic was measured without ('immediate') and with ('aged') 50K thermocycles upon application of (1) the silane-containing self-adhesive composite cement Panavia SA Cement Universal ('SAU'), being light-cured: 'SAU_light', (2) 'SAU_chem': chemically cured SAU, (3) 'SAP_light': light-cured Panavia SA Cement Plus ('SAP'), and (4) 'SAP_CP': SAP light-cured after separate silanization using Clearfil Ceramic Primer Plus ('CP'). CA was also measured on glass ceramic. The cement pastes before and upon mixing were characterized using 29 Si NMR. SB of SAU or SAP onto dentin was measured. Finally, the cement-dentin interface was characterized by TEM and XRD.Results: The immediate and aged SB to glass ceramic of SAU did not significantly differ from those of SAP_CP, while they were significantly higher than those of SAP. CA of SAU did not significantly differ from that of SAP_CP, but it was significantly higher than CA of SAP. 29 Si NMR revealed siloxane bonds after mixture. SB of SAU and SAP to dentin did not show any significant difference. SEM, TEM and XRD confirmed tight and chemical interaction, respectively.Significance: Incorporating silane in a 10-MDP-based self-adhesive composite cement combined efficient silane-coupling ability at the ceramic surface with effective bonding ability at dentin. HighlightsThe clinical procedure to adhesively lute ceramic restorations is complex, by which a simplified application procedure is desirable.Silane-coupling monomers degrade in water; hydrolysis is avoided when the silane-coupling monomer is added to the cement's hydrophobic paste. Once mixed, the silane-coupling monomer hydrolyses to chemically interact with the ceramic surface.The novel silane-containing self-adhesive cement combined efficient silane-coupling ability onto glass ceramics with adequate self-adhesiveness onto dentin.

“…The surfaces of the plates were sandblasted (alumina particle size: 50 μm, pressure: 0.2 MPa) and ultrasonically cleaned with cleaning solution (Solmix AP-7) for 10 min. The blocks were then dried in air, and their surfaces were treated with 100 μL of the surface treatment agent (Multi Primer LIQUID) containing MPTS 27,28) . Specimens without the surface treatment agent were also prepared for comparison.…”

Light-curing resin cements, each comprising one of five different inorganic fillers (non-porous and porous spherical SiO2 particles, irregularly shaped glass and ZrO2 particles, and porous ZrO2 spheres), monomers, and polymerization initiators were prepared to determine the effect of filler morphology on the adhesive strength of the resin cement. The strength of adhesion to a computeraided design/computer-aided manufacturing (CAD/CAM) resin block was investigated mechanically by measuring the tensile bond strength, flexural strength, and elastic modulus. The resin cement containing sub-micron porous ZrO2 spheres had significantly higher tensile bond strength than the other resin cements. The resin cement containing the porous ZrO2 spheres had markedly lower flexural strength and elastic modulus values than the resin cements containing SiO2 and glass fillers.

“…On the other hand, KH-560 silane coupling agent generally contained two different chemical functional groups such as a methoxy functional group and epoxy functional group [39][40][41]. The methoxy functional group after hydrolysed can connect with hydroxyl group contained inorganic materials to form a hydrogen and/or chemical bond and the methoxy functional group can connect with organic molecule.…”

Carbon fibre reinforced polyetheretherketone (CF/PEEK) biocomposites were prepared by the method of hot casting under pressure. The influences of CF surface treatment methods on the tensile strength and modulus of CF/PEEK biocomposites were investigated. The results indicated that the CF modified with concentrated nitric acid was beneficial to improve the tensile strength of CF/PEEK composites. On the contrary, the surface of CF treated by KH-560 silane couple agent has a little or unfavourable influence on the tensile mechanical properties of CF/PEEK composite. Furthermore, the CF surface treatment methods and CF content have a synergistic effect on the mechanical properties of the biocomposites. With the CF content rising, the difference of the effect of different treatment methods on the tensile mechanical properties of CF/PEEK composites is more and more significant. Meanwhile, the tensile stress-strain relationship of the composites showed linear variation and the break strain of the CF/PEEK composites decreased with increasing CF content. The fracture mechanism of the biocomposites gradually changed from ductile to brittle fracture with the increase of CF content. The tensile strength of the biocomposites first increased and then decreased with the increasing CF content. However, the tensile modulus increased monotonically with CF content rising.
