Transition vitreuseIndex. décimale : 667.9 Revêtements et enduits Résumé : The results of studies on the effect of introducing double bonds and siloxane segments to the polyurethaneurea chain on the properties of polyurethane and polyurethane-acrylic/styrene dispersions and coatings are presented. In order to investigate that effect a 23 factorial experiment was designed and conducted. Several properties of dispersions, coatings and films were determined, including,inter alia, particle size, stability, and MFFT (minimum film-forming temperatures) of dispersions, hardness, resistance to water and solvents, adhesion of coatings and mechanical properties, and the glass-transition temperature (Tg) of films. Properties of coatings and films subjected to additional curing were also investigated. Analysing the results of the factorial experiment helped to better understand the mutual effect of several factors on the properties of the investigated materials. ESCA (electron spectroscopy for chemical analysis) and DCA (dynamic contact angle) studies of the surface properties of the coatings were also carried out.

Signaux et signalisationIndex. décimale : 667.9 Revêtements et enduits Résumé : Nine formulations of thermoplastic materials for traffic marking were prepared using a resin based on maleic anhydride modified with rosin in different proportions (18, 22, and 26%). A liquid coconut long oil alkyd resin (100% solids) was employed as a plasticizer.Titanium dioxide was used as a hiding pigment while calcium carbonate and micronized talc were used as extenders. Coarse marble powder facilitated the incorporation of glass beads. The operation was made by employing a double Z mixer heated with oil to obtain a mass temperature of 180-190°C. The mixer was equipped with two asynchronous arms rotating at 46 rpm.Dry and wet abrasion tests were carried out and the results obtained indicated that wearing values are three times greater in the case wet test.It is demonstrated that plasticization degree controls hardness variation as a function of temperature; therefore, a critical point, which is the beginning of an abrupt reduction of hardness, is determined. Water absorption increases when the plasticizer content increases. A matrix correlation of tests results was used to analyze the obtained numeric values.

Polarisation (électricité)Index. décimale : 667.9 Revêtements et enduits Résumé : Ni–SiC nanocomposite coatings were prepared on a brass substrate by electrocodeposition. The electrodeposition was carried out by adding the SiC nanoparticles to a nickel-containing bath. Nickel deposition processes were analyzed by cathodic polarization curves, and the plating parameters were determined preliminarily by analyzing the effects of different technological parameters on the deposition process. Then, electrocodeposition processes were carried out with different concentrations of SiC nanoparticles in the bath. The effects of current density, stirring rate, and SiC nanoparticle’s concentration in the plating bath on the hardness of coatings were investigated by microhardness tests. Besides the microhardness tests, wearing tests and corrosion tests were also applied to the coatings with the highest hardness and coatings of pure nickel. The structures and surface morphologies of the coatings were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM) methods. The experimental results show that the microhardness of the codeposited coating increases with increasing current density and attains a maximum at the SiC concentration of 6 g/L. The decrease in the microhardness at higher SiC concentrations may be due to agglomeration of nanosized particles in the plating bath. Increasing the stirring speed did not give a better quality deposition as coatings produced at low stirring rates always had higher microhardness values than did those at high stirring rates. Furthermore, the Ni–SiC nanocomposite coatings have lower friction coefficient and better corrosion resistance than those of pure nickel coatings.

VernisIndex. décimale : 667.3 Teinture et impression des tissus Résumé : In this study, the effect of accelerated weathering on the surface properties of Scots pine specimens impregnated with wolmanit-CB, tanalith-E, and adolit-KD5 and coated with synthetic and polyurethane varnishes was investigated by measuring surface hardness, glossiness, and colour. Results showed that weathering caused an increase in the hardness of impregnated and varnished specimens, while it caused a decrease in the glossiness of specimens. Surfaces became rougher and darker after weathering in comparison with the initial surfaces of wood specimens. Positive values of the chromatic coordinates indicated that the wood surfaces changed from their original colour to a reddish and yellowish colour. The highest colour change was detected in the specimens coated with polyurethane varnish alone. Both copper-based wood preservative treatment and varnish coating improved the surface properties of specimens in comparison with the surface properties observed on specimens coated with varnish alone.

Tanins végétauxIndex. décimale : 667.3 Teinture et impression des tissus Résumé : The aim of this study was to determine selected surface properties of varnished beech wood impregnated with natural extracts after exposure to accelerated weathering. Beech wood samples were impregnated with aqueous solutions of 5 and 10% mimosa (Acacia mollissima) and quebracho (Shinopsis lorentzii) tannins. After weathering, colour changes (?L*, ?a*, ?b*, and ?E*) in addition to scratch resistance and surface hardness values were calculated and evaluated. As a result of the weathering process, greater colour changes (?E*) were detected in the beech wood samples impregnated with tannins compared with the unimpregnated control samples. The least colour change occurred in the Tanalith-E-impregnated samples. Total colour change was adversely affected with tannin impregnation after the weathering processes. In terms of surface hardness and scratch resistance, the highest values were observed in the mimosa-solution-impregnated and control samples. Furthermore, it was found that scratch resistance and hardness values tended to increase during the first period of weathering and decreased thereafter. Regarding surface properties, the best results were obtained when polyurethane varnish was employed compared with the other varnish types.
