Utilization of the glycerol phase from biodiesel production for the preparation of alkyd paintsSpringer Science and Business Media LLC - Tập 17 - Trang 1207-1216 - 2020
Svetlana Genieva, Elena Mollova
The glycerol phase, obtained as a by-product during the production of biodiesel from sunflower seeds, was utilized for preparation of alkyd paints. Using appropriate treatment, free fatty acids and crude glycerol were obtained from all organic substances in the glycerol phase. Medium and long oil alkyd resins were prepared by esterification of phthalic anhydride with the free fatty acids and crude...... hiện toàn bộ

Graphene oxide (GO) addition to epoxy can improve various properties provided that the GO features, dispersion and interaction with epoxy are optimized. Herein, the challenge of improving the hydrophobicity, flexural behavior and wear resistance of an epoxy coating on steel substrate was addressed by GO incorporation. Three GO concentrations were tested in the epoxy system (0.1, 0.25, and 0.50% m/...... hiện toàn bộ
Effects of added nanoclay for styrene-acrylic resin on intumescent fire retardancy and CO/CO2 emissionSpringer Science and Business Media LLC - Tập 17 - Trang 115-125 - 2019

Coating plywood with intumescent paint is an effective approach to ensure fire safety in materials. This study investigated the effects of applying an intumescent coating with nanoclay and different amounts of Cloisite 15A (1%, 3%, 5%, and 10%) on 4-mm plywood panels. The nanoclay coating had a lower total heat release and peak heat release rate than other approaches, and it significantly enhanced...... hiện toàn bộ
Crosslinked main-chain-type polybenzoxazine coatings for corrosion protection of mild steelSpringer Science and Business Media LLC - Tập 14 - Trang 937-944 - 2017

Bisphenol A/diaminodiphenylmethane (BA-ddm)-based polybenzoxazine precursor was synthesized from 4,4′-diaminodiphenylmethane, bisphenol A, and paraformaldehyde. The curing behavior of BA-ddm was studied by using differential scanning calorimeter and Fourier transform infrared spectrometer techniques. To verify the anticorrosion property, cured polybenzoxazine (PBA-ddm) coatings were prepared on mi...... hiện toàn bộ
Palladium and tantalum aluminide coatings for high-temperature oxidation resistance of titanium alloy IMI 834Springer Science and Business Media LLC - Tập 6 - Trang 257-268 - 2008
I. Gurrappa, A. Wilson, P. K. Datta
The present article explains the efforts made in developing new protective coatings based on palladium, tantalum, and aluminum with considerably improved oxidation resistance for effective protection of titanium alloy IMI 834. Systematic characterization was carried out on as-prepared as well as oxidized coatings and these results are presented. The performance of new coatings was evaluated by gen...... hiện toàn bộ
