“…To study the structural and morphological characteristics of the coatings, Fourier transform‐infrared (FTIR) spectroscopy and scanning electron microscopy/energy dispersive X‐ray analysis (Fedrizzi et al , 1996) have been used. FTIR (Satoh and Urban, 1996; Mamiya et al , 2002) is an established analytical technique for functional group analysis and for study of the hydrogen bonding and phase separation behaviour in polymers, since mid‐infrared spectral changes in band intensity and frequency shifts are known criteria for the presence and strength of hydrogen bonds. SEM is one of the better methods to study the surface morphology of the coating surface.…”

PurposeSilicone and polyester resins have been prepared at various compositions with the purpose of determining the best performing binder system. The coating materials that have been developed have been analysed and evaluated for their protection ability.Design/methodology/approachSilicone and polyester resins have been prepared at various compositions to identify best performing binder system. To evaluate the properties, different analytical methods have been employed. Fourier transform infrared spectroscopy has been utilised to study the chemical changes when the polymers were mixed together. Corrosion resistance has been tested through potential time measurement test using NaCl solution. The surface morphology has been evaluated using scanning electron microscopy/energy dispersive X‐ray (EDX) analysis.FindingsThere is a change in intensity of the peaks and shift in the peak values of the functional groups observed. Scanning electron microscopy graphs show the uniform surface morphology of the systems developed. From the EDX analysis, the composition of the coating material has been found. The results showed that the coatings could protect the substrate for 30 days of immersion in 3 per cent NaCl electrolyte solution.Originality/valueThe paper provides an analysis of coatings containing silicone‐polyester resins.

“…Epoxy-silicone resins may also be cured by means of butyltitanates [27]. Coatings with good protective properties and decreased combustibility may be obtained using a composition of cycloaliphatic diphenylepoxy resin cured with triethylenetetramine and the addition of glycidoxypropyltrimethoxysilane (GPTMS) [28,29]. Silicone resins may be applied for the modification of non-aqueous acrylic dispersions [30,31].…”

Oligomeric glycidylsiloxanes are promising components of hybrid amino-epoxy-siloxane coatings with improved properties. The thermal stability of amine-cured glycidylsiloxane resins were studied by means of thermogravimetric analysis. Four samples of glycidylsiloxane resin, with 18 to 30 glycidyl groups per molecule and molar masses from 5 to 10.5 kg/mol, were cured at 140°C with triethylenetetramine (TETA), isophorone diamine (IDA) and a polyamide (PF). The onset temperatures of degradation, residual masses and heat effects were measured. Maximal degradation rates were registered at temperatures above 400°C. Infrared spectra of the residues indicate that the least stable bonds are Si-C, C-H and C-N. A second degradation step takes place above 700°C resulting in disperse silica.

“…Silane compounds have been increasingly used in coatings (Mamiya et al , 2002), composites (Piotr et al , 2015), adhesion (Indulekha et al , 2018; Liew et al , 2017) and biomaterials (Kaliyathan et al , 2018) because of their impressive physical and chemical properties such as high energy of Si-O bond, surface energy and low surface tension (Liao et al , 2018; Song et al , 2015; Morshedian et al , 2009). Further, improvements in heat and water durability of acrylate are the main direction of the modification of acrylate (Luo et al , 2006).…”

Purpose This paper aims to improve some properties of poly (methyl methacrylate) by copolymerization with butyl acrylate (BA) monomer along with the incorporation of the stable and economical synthesized silicone-containing monomer hexamethyldisilazanomethacryloxyphenyl ketone (HDMK) into the copolymer matrix. Design/methodology/approach For this target solution copolymerization of methyl methacrylate (MMA), BA and HDMK were carried out using a 250 mL four-necked round-bottom flask. Before solution polymerization start-up, the reaction vessel was first charged with 34.8 mL toluene and heated to 170 Â°C with stirring and reflux cooling. A monomer mixture of 25.86 g (260 mmol) MMA, 26.40 g (200 mmol) BA, 3.00 g (8.60 mmol) HDMK and 0.45 g (2.00 mmol) dibenzoyl peroxide was added continuously from the dropping funnel over a period of 4 h. Findings The HDMK was successfully synthesized and the water resistance of acrylic resins was improved because of the existence of HDMK. Research limitations/implications The materials that were used in this research paper had a reasonably low cost. Also, the procedures for synthesis of monomers and polymers were extremely easy because there was no need for high pressure or temperature and no dangerous solvents were used. Practical implications The acrylic resin that contained HDMK was used to synthesis a white architectural paint for exterior coating. Examining the paint characteristics has shown acceptable washing and abrasion resistance, good brushing, excellent storage stability and great surface coating. Originality/value HDMK was synthesized for the first time.
