  • The usage of novel acrylic-modified water-reducible Alkyd resin obtained from post-consumer PET bottles in water-based paint formulation
    Journal of Material Cycles and Waste Management, 2019
    Co-Authors: Özge Naz Büyükyonga, Işıl Acar, Nagihan Akgün, Gamze Guclu

    Abstract:

    Glycolysis reactions of waste polyethylene terephthalate (PET) flakes obtained from post-consumer water bottles were carried out at 220–250 °C using diethylene glycol, dipropylene glycol and triethylene glycol, and molar ratios of PET/glycol in the glycolysis reactions were chosen to be 1/3. The obtained glycolysis products were used in the synthesis of medium-oil acrylic-modified water-reducible Alkyd Resins. Acrylic modification was carried out using methacrylic acid–maleic acid copolymer synthesized in our laboratory. The structure of the acrylic copolymer was investigated with FTIR analysis. Films of the modified Alkyd Resins were prepared and their physical and chemical surface coating properties were investigated. When surface coating test results were evaluated, it was observed that waste PET had no adverse effect on these properties of acrylic-modified water-reducible Alkyd Resins. Then, two water-based paints were prepared using PET-based acrylic-modified water-reducible Alkyd resin and reference acrylic-modified water-reducible Alkyd resin as binder. Wet paint properties and physical/chemical dry film properties of paints were determined. When the physical surface coating test results were evaluated, no difference was observed between the properties of both paints. If we evaluate the results of chemical surface coating properties, the hot water and alkali resistance of waste PET-based paint was considerably higher than the reference resin.

  • Synthesis and film properties of long oil Alkyd resin/organo clay nanocomposite coatings
    Research on Chemical Intermediates, 2015
    Co-Authors: Müzeyyen Tahmaz, Işıl Acar, Gamze Guclu

    Abstract:

    This study deals with the synthesis and investigation of the surface-coating properties of nanocomposite long oil Alkyd Resins which contain different ratios of organo clay. The aim is to investigate the effects of organo clay addition on the surface-coating properties of the Alkyd Resins. For this purpose, organo clay-modified long oil Alkyd Resins were synthesized by an in situ polymerization method. Alkyd Resins were formulated to have an oil content of 60 % using a K Alkyd constant system. The obtained nanocomposite Alkyd Resins were diluted with xylene of 60 % solid content, and films were prepared using 50-μm applicators from these solutions. After the nanocomposite Alkyd resin films had been dried at room temperature for 72 h, physical and chemical surface-coating properties and thermal oxidative degradations were investigated. In addition, surface morphology analyses of nanocomposite Alkyd resin films were also performed by scanning electron microscope. Incorporation of organo clay into Alkyd resin structure has significantly improved physical and chemical film properties and thermal stabilities of Alkyd Resins. As a result, long oil Alkyd Resins containing organo clay are suitable for manufacturing surface-coating binders.

  • a novel type of organo clay containing Alkyd melamine formaldehyde Resins
    International Journal of Polymeric Materials, 2013
    Co-Authors: Işıl Acar, Tulin Banu Iyim, Gamze Guclu

    Abstract:

    In this study, organo clay-modified Alkyd Resins were synthesized and these modified Alkyd Resins were cured with different ratios of melamine formaldehyde resin for the first time. Alkyd Resins were blended with 30% and 40% of a commercial melamine-formaldehyde resin. Alkyd-melamine formaldehyde resin films were cured at 140°C for 2 h in an oven. The effect of organo clay addition on the physical and chemical film properties was investigated. These surface coating properties of the Resins enhanced with amount of organo clay up to 2–3%. These Resins are suitable for manufacturing of high-performance industrial baking enamels.

  • comb shaped silicone Alkyd Resins with high solid content
    Progress in Organic Coatings, 2017
    Co-Authors: Maria C Mejia, Juliana Palacio, Edwin A Murillo

    Abstract:

    Abstract An unique com-shaped silicone-Alkyd Resins (SiAR) were synthesized with high solid content (65 wt%) prepared from an Alkyd resin (AR) and a varying weight% (5, 10, 15, 20) of silicone moiety (Z-6018) by etherification reaction. The viscosity and the hydroxyl value (OHV) of the SiAR were found to be higher than those of the AR. The formation of the SiAR was confirmed by infrared spectroscopy and mass spectrometry analysis. The glass transition temperature (T g ), thermal stability, and molecular weight of the SiAR, increased with increasing the silicone content and compared with those of the AR. The results of chemical resistance showed that the SiAR exhibited a better resistance than AR against 0.1 M sodium hydroxide (NaOH) solution.

  • styrene hydroxyethyl acrylate copolymer based Alkyd Resins with a comb type structural morphology obtained with a high solid content
    Journal of Applied Polymer Science, 2016
    Co-Authors: Maria C Mejia, Edwin A Murillo

    Abstract:

    Nowadays, so many studies are being carried out with the goal of obtaining environmentally friendly materials. In this study, styrene–hydroxyethyl acrylate copolymer (St-co-HEA) based Alkyd Resins with high solid contents and comb-type structural morphologies were synthesized from St-co-HEA and macromonomers [MMs; dimethylol propionic acid modified with different proportions of tall oil fatty acids (TOFAs)]. The molar mass and gloss values of St-co-HEA were lower than those of the Alkyd Resins, but the thermal stability, viscosity, and glass-transition temperature exhibited the opposite behavior. In all cases, the conversion percentage was higher than 80 %. The hydroxyl value and viscosity of the Alkyd Resins decreased with the TOFA content present in the MMrs, but the molar mass and the thermal stability increased. The rheological behavior of these Resins was mainly pseudoplastic. Furthermore, the viscosity values were lower than 10 Pa s. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43996.

  • hyperbranched phenolic Alkyd Resins with high solid content
    Progress in Organic Coatings, 2015
    Co-Authors: Pedro P Vallejo, Betty L Lopez, Edwin A Murillo

    Abstract:

    Abstract Hyperbranched phenolic-Alkyd Resins (HPARs) with high solid content (70 wt%) were obtained in this study, with the aim of obtaining new environmentally friendly materials. The HPARs were synthesized from hyperbranched polyester polyol of fourth generation (HBP), phenol, and tall oil fatty acids (TOFA). In all cases the proportions of HBP (75.40 g) and TOFA (69.60 g) were kept constant, and those for the phenol were 10 (HPAR1 resin), 20 (HPAR2 resin) and 30 wt% (HPAR3 resin). The structural, rheological, thermal and film properties of the HPARs were evaluated and compared with those of a hyperbranched Alkyd resin (HBAR) obtained in our earlier work with the same proportion of HBP and TOFA employed in this study. The reaction between TOFA and phenol with the HBP was evidenced by acid value ( AV ), hydroxyl value ( OHV ) and nuclear magnetic resonance (NMR) analyses. The modification percentage of the HBP increased with the phenol content, which was higher than 60%. The conversion percentage of TOFA was higher than 90%. The molar mass of the HPARs determined by gel permeation chromatography (GPC) was upper than that of the HBP. Dynamic light scattering (DLS) analysis showed that the intensity distributions of the HPARs were monomodals except for the HPAR1 resin. HPARs gloss and hardness values increased with phenol content. Glass transition and thermal decomposition temperatures, viscosity and hardness values were higher for HPARs than HBAR.

  • novel waterborne hyperbranched acrylated maleinized Alkyd Resins
    Progress in Organic Coatings, 2011
    Co-Authors: Edwin A Murillo, Betty L Lopez

    Abstract:

    Abstract Different waterborne hyperbranched acrylated-maleinized Alkyd Resins (HBRAAM) were synthesized by modifying a hyperbranched Alkyd resin (HBRA) with three different butylmethacrylate–maleic anhydride copolymers (BMA–MA) in the presence of p-toluenesulfonic acid (PTSA). The HBRAAM Resins were characterized by using infrared analysis, iodine value, hydroxyl value, vapor pressure osmometry (VPO), dynamic light scattering (DLS), acid value, rheological analysis, differential scanning calorimetry, adhesion, flexibility, drying time, gloss, hardness and chemical resistance to solvents. The iodine value and hydroxyl value decreased with the amount of BMA–MA copolymer employed in the synthesis. Infrared analysis, VPO, and hydroxyl values allowed us to conclude that the reaction between HBRA Resins and BMA–MA copolymers occurred. The viscosity of the HBRAAM Resins was between 50.5 and 468 Pa s. All HBRAAM Resins presented good properties of adhesion, flexibility, drying time, gloss, hardness and chemical resistance.

  • effect of tall oil fatty acids content on the properties of novel hyperbranched Alkyd Resins
    Journal of Applied Polymer Science, 2011
    Co-Authors: Edwin A Murillo, Pedro P Vallejo, Betty L Lopez

    Abstract:

    Hyperbranched Alkyd Resins (HBRA) were synthesized by modification of hydroxylated hyper- branched polyester (HBP1-4) with tall oil fatty acids (TOFA). The core is a hydroxylated hyperbranched poly- ester of fourth generation with OH groups in the periph- ery (18), which is endcapped with tall oil fatty acids. The occurrence of these reactions, HBP1-4 and TOFA, was determined by making use of acid value, nuclear magnetic resonance, and hydroxyl values. The effects of TOFA and HBP1-4 on properties of the HBRA Resins were investigated by vapor pressure osmometry, differential scanning calorimetry, thermogravimetric anal- ysis, friction resistance, and hardness. The Resins with higher modification percentage (HBRA4) presented the best thermal and hydrolytic stability, but lower friction resistance and hardness. All HBRA Resins presented amorphous characteristics, OH groups, and double bonds in the periphery. V C 2011 Wiley Periodicals, Inc. J Appl Polym Sci 120: 3151-3158, 2011
