Crosslinking mechanism of an anhydride‐cured epoxy resin as studied by fourier transform infrared spectroscopy Fourier transform infrared spectra, including absorbance difference spectra, are presented which indicate that the accepted mechanism of tertiary amine-catalyzed copolymerization of cyclic anhydrides a...
Further, the surface of the irradiated epoxy resin was analyzed by x-ray photoelectron spectroscopy (XPS) to evaluate the functional group concentration after exposure to different doses of VUV light. The difference in principle between FTIR-ATR and XPS analyses was used as the basis to examine ...
In this study, resin-dentin interfaces produced by two dentin adhesive systems, Optibond (OPTI, Kerr) and Scotch-bond Multi-Purpose (SBMP, 3M), were comparatively investigated by TEM in epoxy-embedded and nonembedded non-demineralized sections. The hypothesis advanced was that no difference in ...
Epoxy/BaTiO3 composite embedded capacitor films(ECFs) were newly designed for high dielectric constant andlow-tolerance (less than 5%) embedded capacitor fabricationfor organic substrates. In terms of material formulation, ECFsare composed of a specially formulated epoxy resin and latentcuring agent, an...
(CE)modified epoxy resin were investigated by the thermal deformation meter and FT-IR.The results showed that the HDT of epoxy could be improved greatly by adding cyanate ester.The influence degree of curing temperature on the HDT of systems with different content of CE was obvious difference....
LUVOTIX® - Rheological additives for 2-component high-solid paints on an epoxy resin basis 来自 tecmos.com 喜欢 0 阅读量: 110 摘要: Figure 2 shows the flow curves of a formulation based on epoxy resins without and with 2 % of a rheological additive, measured immediately after the ...
Ultrasonic welding is a joining process based on the introduction of high-frequency and low-amplitude vibrations transverse to the interface to be welded [10,11]. In order to promote local heat generation an energy director (ED), either resin protrusions molded on the adherends or a loose ...
resin was added into the suspension. Meanwhile, the mass of the mixture was measured and recorded. The mixture was then kept being stirred with an electric stirrer at 80 °C for 4 h. After that, the mixture was weighed every ten minutes and the mass difference was calculated. When ...
Here, core–shell impact modifier particles (CSIMPs) and multiwalled carbon nanotubes (MWCNs) were used as reinforcing agents for improving the toughness and tensile properties of epoxy resin. For this purpose, emulsion polymerization technique was exploited to fabricate poly(butyl acrylate-allyl metha...
