Abstract:Coatings for high temperatures (HT > 400 • C) are obtained from interpenetrating polymer network (IPN) binders formed by simultaneous polymerization of silicone and epoxide pre-polymers. A ceramic layer; mainly composed of silica and fillers; remains on the metal surface after a thermal treatment at 450 • C. The layer adhesion and the inorganic filler's distribution have been investigated by, firstly, exchanging the organic substituents (methyl and phenyl) of the silicone chains and, secondly, by adding conductive graphene nanoplatelets with the aim to assure a uniform distribution of heat during the thermal treatment. The results are evidence that different substituent ratios affect the polymer initial layout. The adhesion tests of paint formulations are analysed and were related to instrumental analyses performed using glow discharge optical emission spectroscopy (GDOES); thermal analyses (TG/DTA and DSC); electron microscopy with energy dispersive X-ray analysis (SEM-EDX). A greater resistance to powdering using phenyl groups instead of methyl ones; and an improved distribution of fillers due to graphene nanoplatelet addition; is evidenced.

The industrial application of a vegetable oil is determined by the oil properties. This work was undertaken to alter the properties of Jatropha curcas Kernel oil and possibly find new applications for it. The seed kernels were roasted to different temperatures (140 to 230°C) and the physicochemical properties of the cold hexane and hot water extracted oils were studied. The oil yield, saponification, iodine, acid and peroxide values were affected by roasting temperature and method of extraction and these showed significant difference (p < 0.05). The calculated fuel properties: cetane number and calorific value were improved upon roasting, with cold hexane extracted oils yielding better results. Roasting improved the properties of the oil as diesel substitute but its suitability for use in paints and surface coatings formulation was reduced. The hot water extracted oil showed improved properties for soap production.

“…One of the most commonly used group of curing agents for liquid epoxy resins are aliphatic [9][10][11][12][13][14], or aromatic [15][16][17][18] amines or imidazole derivatives [19,20]. Recently, among frequently studied modifiers of epoxy polymers are silicone containing compounds, including various siloxanes or silsesquioxanes [21][22][23][24][25][26][27][28][29][30]. The effect of two low-molecular siloxanes: 1,3-Bis(glycidyloxypropyl)-1,1,3,3-tetramethyldisiloxane and 1,3-bis(aminopropyl)-1,1,3,3-tetramethyldisiloxane on performance properties of liquid bisphenol A epoxy resin cured with triethylenetetramine were reported in our previous paper [25].…”

The reactivity of a system comprising commercial epoxy resin Epidian Ò 6 (E6) and triethylenetetramine (Z-1) hardener was studied. The system was modified with two low-molecular siloxane modifiers: 1,3-bis(glycidyloxypropyl)-1,1,3,3-tetramethyldisiloxane (DS1) and 1,3-bis(aminopropyl)-1,1,3,3-tetramethyldisiloxane (DS2). The modifiers replaced 10 mass% of E6 or Z-1, respectively. The systems E6/DS2 and DS1/Z-1 were also studied. Enthalpy of curing was determined for all systems in isothermal conditions and dynamically, i.e., in the range of 0-250°C with linearly increasing temperature at the rate of 2, 5, 10, and 20°C min -1 . The activation energy of curing was determined using isoconversional methods by Friedman and Kissinger-Akahira-Sunose. The epoxy systems containing siloxane modifiers had generally lower activation energies than the reference E6/Z-1 system. The time to gelation measurements were taken using the temperaturemodulated differential scanning calorimetry.
