SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 667.9 Revêtements et enduits Résumé : Nano-TiO2-dispersed polymeric coatings have been extensively studied in recent years owing to their photocatalytic-induced self-cleaning characteristics. However, durability and long-term retention of self-cleaning performance of such coatings remain a challenge for practical applications. In the present work, we report the self-cleaning properties of nano-TiO2/silicone soya alkyd-based coating formulations comprising 0.5–5 wt% of nanofiller as well as conventional additives of rutile TiO2 and BaSO4. The nanocomposites were prepared by an in situ process involving dispersion of nano-TiO2 in soya oil, soya alkyd synthesis by alcoholic process, followed by silicone modification. The coatings prepared from the nanofiller-dispersed resin showed significant UV radiation-induced hydrophilicity and photocatalytic degradation of methylene blue (MB) solution. A coating formulation with 2 wt% of nano-TiO2 loading showed a decrease in water contact angle from 87° to < 10° after 24 h of UV radiation exposure and a 50% decrease in intensity of the 664-nm absorbance peak of MB solution after 8 h of UV irradiation. Further, Fourier transform infrared spectroscopy in reflectance mode (ATR-FTIR) and thermogravimetric analysis (TGA) studies revealed minimal degradation of the host matrix after 500 h of accelerated weathering studies with retention of self-cleaning characteristics. These results imply that silicone-modified alkyd resin can be a suitable host matrix for combining the requisite properties of self-cleaning, organic contaminant degradation, photocatalytic stability, and weathering resistance for sustainable self-cleaning applications.

Structure chimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : The aim of this work was to study the morphology and physical properties of siloxane–polyacrylate (SPA) dispersion and coating films. The SPA dispersion was synthesized by seeded emulsion polymerization using two different types of silane coupling agents, i.e., vinyltriethoxysilane (VTES) and 3-(trimethoxysilyl) propyl methacrylate (MPTMS), at 1–9% by weight. The effect of the type and content of silane coupling agent used in the SPA dispersion synthesis on the resulting morphology and physical properties of the obtained SPA dispersion and coating films were studied. The results revealed that SPA dispersion synthesized using VTES exhibited a smaller particle size and a higher stability than those using MPTMS. Furthermore, the hydrophobic surfaces and water repellence of the coating films using VTES in the emulsion were higher than those using MPTMS, due to the smoother surface morphology.

Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : Phosphorus source in transparent intumescent fire-retardant (IFR) coatings plays a crucial role in determining its performance against protecting structures from fire. In the present work, naturally occurring environmentally benign phosphorus-rich phytic acid (PA) was used as a phosphorus source. Phosphate ester resin (PER) was synthesized using PA and hyperbranched polyol (HBP), which was then used as a precursor for preparing optically transparent IFR coatings. The prepared PER was further modified with hydrogenated bisphenol-A (DGEHBA)-based epoxy resin in different wt% (25–100) to get PER-1, PER-2, PER-3, and PER-4, respectively. The formation of the PER resins was confirmed by Fourier transform infrared spectroscopy (FTIR), 13C-nuclear magnetic resonance, 31P-nuclear magnetic resonance spectroscopy (31P-NMR), and acid value analysis. The transparent IFR coatings were prepared by suitably mixing PER with hexamethoxy methyl melamine (HMMM) resin, and their performance was studied by measuring mechanical properties, optical transparency, thermal stability, fire retardancy, and smoke emission characteristics using various analytical instruments. The combination of PA and hyperbranched polyol improved the physicomechanical properties of PER-based transparent IFR coatings. The char formed after burning was also analyzed using FESEM and UTM. Results revealed that phytic acid and HBP combination increased the height as well as strength of the char. Among the prepared transparent IFR coatings, PER-0 and PER-1 have shown higher char height and strength.

Stabilité thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : In recent years, the chemical industry is not only striving to produce the best possible products for various applications, but the new products should ideally be based on renewable resources. The ideal case of "cradle to cradle" is generally not achievable in the coatings industry, as maximizing product life and preventing product degradation in the environment is usually one of the main goals of the coatings industry. Therefore, if the coatings industry wants to act sustainably, its efforts should be focused on renewable raw materials. This paper presents a process that makes the renewable raw material phytic acid easily accessible for conventional epoxy and polyol resin coating systems through hydrophobization- and oligomerization. Phytic acid, as a phosphorus reservoir in plants and with beneficial properties for corrosion protection and as a flame retardant, could be a new base for various coatings. In this work, a simple one-pot oligomerization of phytic acid with green mono- and difunctional alcohols is investigated. The aim of this work is to create a phytic acid hardener system based on renewable raw materials that can produce coatings with solvent-based epoxy and polyol binders as well as water-based epoxy binders. The successful reaction was observed by infrared, 1H-NMR, and 31P-NMR spectroscopy and the acid equivalent weight was determined by conductivity titration. The renewable curing agent was then used equivalently with different binder systems to prepare coatings. Crosslinking and glass transition temperature were monitored using oscillatory rheology. The coatings were applied to glass plates and the pendulum hardness was measured. A simple heating test followed by 31P-NMR and IR spectroscopy was also performed to demonstrate the stability of phytic acid under reaction conditions.
