It was further modified by 2,4-toluene diisocyanate (TDI) in 10–30 wt% of polyetheramide to develop a series of moisture curing urethane-modified polyetheramide resins (UMCOPEtA). The synthesized resin was characterized using 1H NMR, 13C NMR, FTIR and solubility in various organic solvents at room temperature. The thermal and curing behavior of the resin was investigated using thermogravimetric analysis and differential scanning calorimetric techniques. The physico-chemical properties such as hydroxyl value, iodine value, specific gravity and mechanical properties like scratch hardness, impact, and flexibility were determined by standard laboratory methods. Coatings of UMCOPEtA resin were prepared on mild steel panels to evaluate chemical resistance performance against acid, alkali, water and xylene. The newly developed UMCOPEtA coatings showed improved hardness, impact, gloss, water and chemical resistance when compared with unmodified polyetheramide coatings, and thus were found to be suitable as a high performance coating material.

Titre : High scratch resistant anticorrosive ceramic paints Type de document : texte imprimé Auteurs : S. Vishnu Shankar, Auteur Année de publication : 2000 Article en page(s) : p. 111-113 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Peinture anticorrosion' Formulation 'Pigment minéral' 'Matière charge' Céramique 'Propriété mécanique' Feuil 'résistance rayure' 'Résistance choc' abrasion''Etude expérimentale' Index. décimale : 667.9 Revêtements et enduits Résumé : Ceramic high scratch resistant anticorrosive paints offer high scratch resistance to the extent of 20 kg when painted at 100 microns coatings thickness. This coating offers high solid-high scratch-high impact-high wear-chemical resistance properties. All these combined properties helps in enhancing the overall properties of the painted component by a factor of 5-7 times when compared to conventional coating systems. The dry film coatings exhibit enhanced substrate adhesion, intercoat adhesion, thermic shock, hot water, anti-rust properties. These ceramic paints are basically recommended for aircraft and defence purposes where high scratch and abrasion resistance are required. This can be conveniently used where high built coatings are required, like aircraft leading edge areas, machine tools industries, automobile components, plant equipments, machinery components, home appliances, etc. Ceramic paints are available in various shades and at affordable prices. They can be used by conventional spray methods as well as by brush painting.

Titre : Measurement by scanning force microscopy of the scratch and mar resistance of surface coatings Type de document : texte imprimé Auteurs : W. Shen, Auteur ; C. Ji, Auteur ; F. Jones, Auteur ; M. P. Everson, Auteur ; A. Ryntz, Auteur Année de publication : 1996 Article en page(s) : p. 253-256 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Peinture 'Matériau revêtement' 'Propriété mécanique' Feuil 'Résistance rayure' 'Etude expérimentale' 'Microscopie force balayage' Index. décimale : 667.9 Revêtements et enduits Résumé : Scratch and mar resistance are a very desirble characteristic of coatings. Conventional hardness does not provide relevant data about them. The scanning force microscope has been used to carry out a micro-scratch test. This direct measurement provides a reliable comparison of scratch resistance for samples measured under the same condition. To characterize the scratch and mar resistance, a micro-scratch resistance test may be introduced for coatings. It is defined as the force applied normal to the surface divided by the cross section area of the scratch. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=17048
