Vernis en phase aqueuse -- AdditifsIndex. décimale : 667.9 Revêtements et enduits Résumé : A non-crystalline aluminum silicate related to allophane (i.e., clay mineral) was synthesized by a hydrothermal reaction after which the synthetic mineral was mixed with clear or multicolored aqueous emulsion paint as a nanofiller. The nanofiller was revealed by X-ray diffraction to have an amorphous morphology, showed a narrow particle size distribution with a volume mean diameter of 1.2 µm and indicated a specific surface area of 228 m2/g. Clear films prepared with the nanofiller had significantly improved wettability compared to a blank film. The results of outdoor exposure tests exhibited that multicolored films with the nanofiller showed higher antifouling ability than films with a commercially available silica filler. A proposed antifouling mechanism is that the proportion of Si-OH and Al-OH active sites exposed on the nanofiller surface had a significant effect on the surface wettability of the films and exquisitely controlled the sliding of rain droplets.

Traitement thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : The UV protective coatings were developed by incorporating triazine derivative organic UV stabilizers into inorganic titania particles which were produced by sol–gel method. The objective of this study is to delay the color change of heat-treated wood subjected to outdoor conditions. The protective coatings were prepared in air at room temperature. The coatings were not further treated thermally after their application to heat-sensitive materials. Coatings were applied to heat-treated jack pine wood. Subsequently, accelerated aging tests were carried out using coated and uncoated jack pine samples. The color change of the wood samples was studied, and the results were compared. Also, the morphological analyses were done using XPS after having weathered the wood at different times.

Revêtements protecteurs -- DétériorationIndex. décimale : 667.9 Revêtements et enduits Résumé : Cathodic protection (CP) is widely used internationally as a major corrosion mitigation technique in pipeline integrity. The use of protective coatings in conjunction with cathodic has been an extensive record of proven performance in the protection structure including underground pipelines, ships, underground storage tanks, pipings, and tank bottoms. The use of both a protective coating and a cathodic protection system presents unique design, installation and maintenance consideration. However, if the coating is not properly chosen there will be premature failure of adhesion between a coating and the material substrate which directly attributed to cathodic protection conditions. This paper will discuss about the correlation of vapour permeability with the extent of cathodic disbondment of different coating materials under accelerated conditions. Note de contenu : 1.

ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : The objective of this work was to compare the anticorrosion effects of organic coatings containing zinc metal consisting of either lamellar particles or isometric particles and to reduce the zinc metal content of the coatings while preserving their high anticorrosion efficiency. The optimization and Zn metal content reduction can be achieved using zinc with a lamellar particle shape and application of conductive polymers. Conductive polymers are expected to enhance the electrochemical effect of zinc metal in paints. Organic coatings with lamellar zinc particles also exhibit better mechanical properties. Optimization of the amount of zinc lamellar particles could promote a wider use of this material in anticorrosion paints. The conductive polymers used in this work included polyaniline phosphate, polyaniline benzoate, and carbonized polyaniline. A solvent-based epoxy–ester resin served as the binder. Model paints consisting of this resin and containing different concentrations of polyaniline phosphate, polyaniline benzoate, and carbonized polyaniline were prepared. The paints were tested at the critical pigment volume concentration (CPVC) of Zn dust and at lower Zn dust concentrations, specifically 2% below the CPVC. The paints containing combinations of zinc and a conductive polymer contained the sum of the pigments just below the CPVC of the zinc dust species used. This implies a level of 39% of (PVCZn-lam) for the systems with lamellar zinc and a level of 61% of (PVCZn–sf) for the systems with spherical zinc. The pigment volume concentration (PVC) of the conductive polymers in the zinc-containing paints was (based on results obtained previously) 1%, 5%, and 10% in the systems with lamellar zinc and 1%, 5%, 10%, and 15% in the systems with spherical zinc. The organic coatings were subjected to accelerated cyclic corrosion tests and electrochemical measurements. The sample containing polyaniline carbonate (PVC = 1%) and spherical zinc exhibited a significantly lower corrosion rate as compared to that of uncoated steel.

Vernis -- Propriétés mécaniquesIndex. décimale : 667.9 Revêtements et enduits Résumé : A series of four polyol macromers with similar hydroxyl number was prepared by reacting palm fatty acid distillate with neopentaglycol, pentaerythritol, and separate equimolar amounts of isophthalic acid (IPA), terephthalic acid (TPA), phthalic anhydride (PA), and adipic acid (AA). Each macromer was then copolymerized with 2-hydroxylethyl acrylate (2-HEA) and toluene diisocyanate to produce the UV curable resins labeled as UA-IPA, UA-TPA, UA-PA, and UA-AA, respectively. The glass transition temperature (Tg), pendulum hardness, and adhesion properties of the cured films were studied. In general, all the resins produced coatings with high gloss and good adhesion. When accelerated weathering tests were carried out, films of UA-TPA could withstand UVA exposure up to 1500 h. When subjected to methyl ethyl ketone double rub test, cured films of UA-IPA and UA-TPA could withstand the highest double rubs at 90 times, followed by UA-PA and UA-AA at 45 and 15 times, respectively. Under salt spray corrosion test for 720 h, cured films showed good corrosion resistance with no observable blistering, except for UA-AA that showed slight blistering. Excellent water resistance was achieved by all cured films with good adhesion and minimal gloss reduction.
