Epoxy resins Araldite

For the calibration of the constructed sensors and the electronic tongue, different stock solutions containing a single ion or both are prepared. These are KC1 solutions in doubly distilled water with concentrations 0.001 M, 0.01 M, 0.1 M and 1.0 M, NH4C1 solutions in doubly distilled water with concentrations 0.001 M, 0.01 M, 0.1M and 1.0 M, plus two KC1 and NH4C1 mixed solutions in doubly distilled water with concentrations of 0.01 M and 0.1 M of both ions, respectively. Accessory materials to facilitate construction and electrical connection are TV antenna coaxial cable, alligator clips (for an easy connection of the coated wire sensors) and epoxy resin (Araldit). [Pg.1247]

Cover with an epoxy resin (Araldit) the portion of the exposed wire not covered with membrane. Apply epoxy resin around a short portion of the coaxial cable near the exposed wire. This step assures that only the coated wire is in contact with the analyte s solution. Leave the epoxy resin to cure for 24 h at 40°C. [Pg.1248]

Lucite positive relief structures. Epofix was selected as the chip substrate, among acrylic-polyester resin (Casolite) and epoxy resin (Araldite), because of its having the best mechanical properties and the least chemical interference needed for fabricating the MS chip [780]. In another report, PDMS was chosen over epoxy to fabricate MS chips because of its less chemical noises (interferents) in MS, and over polyurethane because of good adhesion properties. Even so, in the use of PDMS its curing (at 70°C) should be carried out for at least 72 h to further reduce the chemical noise [800]. [Pg.27]

Hadjistamov (1999) examined the effect of nanoscale silica on the rheology of silicone oil and uncured epoxy-resin (araldite) systems. Shear thickening and yield-stress-like behaviour were observed and found to be due to a build-up of network structure associated with the nanocomposite phase. [Pg.370]

Some typical results are shown in Figure 16.2 (LLE for PS/acetone), Table 16.4 (infinite dilution activity coefficient for PBMA solutions in a variety of solvents). Tables 16.5 and 16.6 (activity coefficients of low- and heavy-molecular-weight alkanes in asymmetric athermal-alkane solutions). Table 16.7 (VLB for ternary polymer-solvent solutions). Figure 16.6 (VLB calculations for systems containing the commercial epoxy resin Araldit), and Table 16.8 (comparison of LLE results from various thermodynamic models). [Pg.711]

To obtain reproducible results, it was necessary always to use the same syringe, because although any particular syringe can deliver a reproducible amount, apparently similar syringes deliver considerably different amounts. It was also found necessary to use a syringe with a needle cemented in place with epoxy resin (Araldite) because syringes with detachable needles delivered different amounts at different times for no obvious... [Pg.127]

The epoxy resins Araldite LY556 with the hardener HY932 and Ruetapox LV 0164 with a polyetheramine hardener (Jeffamine T-403) were used. The Jeffamine T-403 can be used as hardener and/or as flexibilizer for epoxies and leads to thermosets with improved ductility. [Pg.8]

Materials Description. Three CIBA-GEIGY epoxy/hardener systems were studied Araldite 6010/906, Araldite 6010/HY 917 and Araldite 6010/972 with stoichiometries 100/80, 100/80 and 100/27, respectively. Araldite 6010 was a DGEBA epoxy resin. The hardeners 906, HY 917 and 972 were, respectively, methyl nadic anhydride (MNA), methyltetrahydro phthalic anhydride (MTPHA) and methylene dianiline (MDA). These systems were investigated previously for the matrix controlled fracture in composites (6-8). The curing cycles used can be found in (6). The ideal chemical structures of the systems are shown in Table I. Neat resins were thoroughly degassed and cast into 1.27 cm thick plates for preparation of test specimens. [Pg.137]
