PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.
Revêtements:PeintureIndex. décimale : 667.9 Revêtements et enduits Résumé : Epoxy polyamide based paint was coated on glass plate and mild steel panels inoculated with pseudomonas bacterial species. The weight gain experienced in the coated panels after 90 days of immersion, indicates the polymer-coated surface. Similarly the impedance data revealed that the enzyme produced by the pseudomonas did not influence the coating surface. But after 90 days the resistance value has decreased due to diffusion of water into the polymer coated surface. The FTIR analysis confirmed the epoxy polyamide coating has strong resistance to microbial activity resulting in no biodegradation. Note de contenu : - Preparation of coated panels

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 667.9 Revêtements et enduits Résumé : Nano-technology involves the manipulation of materials at a molecular level in order to make new materials with superior properties. The development of nano-materials, a category ofnano-technology, has potential for applications in a number of local industries. After few years of research work, an innovative new clear IPN (Interpenetrating Polymer Network) based on CNSL-S and silicone resin binder is developed and by using ceramic pigments as nano-particles for high temperature surroundings. Ground breaking nano technology ensures that the new product is substantially more impact resistance and good glossy with very good scratch resistance as conventional heat resistant coatings. The developed coatings provided long term benefits to the ferrous metal in the corrosive as well as high temperature environments. The XRD and TGA/DTA analysis were used to find out the thermal behaviour of the coatings. The EIS studies were carried out to ensure that the coating life lasted for a longer time.

Titre : Comparative performance of coating system on steel surface at laboratory and Chennai naval base environment Type de document : texte imprimé Auteurs : M. Selvaraj, Auteur ; M. Natesan, Auteur ; K. Maruthan, Auteur ; P. Jayakrishnan, Auteur Année de publication : 2003 Article en page(s) : p. 49-54 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Maintenance coating systems viz. vinyl, epoxy - polyurethane and polyurethane were coated on wire brushed steel surface and exposed at Chennai naval base for 18 months and in a salt spray chamber for 720 hrs. After this duration, the panels were removed and subjected to impedance measurement studies in 0.5 M sodium chloride solution. The photographs of salt spray chamber exposed panels and those exposed in atmosphere indicate that the latter gets highly corroded when compared to the panels in the salt spray chamber. This is mainly due to the atmospheric corrodant present in the air in addition to the marine environment. The AC impedance measurement shows that the vinyl and epoxy-polyurethane coating system exhibited 109 ohm-cm2 resistance even after 720 hrs salt spray and a 18 month exposure at the navel base. But the resistance produced by the polyurethane system is in the order of 106 ohm-cm2 and 104 ohm.cm2, which shows comparatively poor protective property of this system. This study indicates that better correlation is possible between exposure studies and the electrochemical methods of evaluating the coating systems. The studies further conclude that vinyl and epoxy-polyurethane coating systems can be used as maintenance coating system for steel structures at the navel base environment in Chennai.

Titre : Comparison of the electrochemical behaviour of MIO, TIO2 pigments in chlorinated rubber binders Type de document : texte imprimé Auteurs : M. Selvaraj, Auteur Année de publication : 1996 Article en page(s) : p. 33-38 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Peinture anticorrosion' 'Pigment minéral' Fer Oxyde 'Structure lamellaire' 'Concentration pigmentaire volumique' 'Caoutchouc chlore' 'Propriété électrochimique' Feuil Index. décimale : 667.9 Revêtements et enduits Résumé : Barrier coatings containing lamellar structural pigments are formulated at a lower range of pigment volume concentration (PVC) than the spherical structural pigmented coating. The low PVC lamellar structural pigmented formulation protects the steel structures for longer duration than the higher PVC spherical structural pigmented formulation. In this study, chlorinated rubber based coatings pigmented with MIO (25 PVC) and titanium dioxide (36 PVC) are prepared. These coatings are evaluated by electrochemical techniques such as potential, polarisation and impedence measurements in 3% sodium chloride solution for regular intervals. The results are also well comparable with accelerated salt spray test. The experimental result shows that the MIO pigmented coating protects the steel substrates for longer duration than the TiO2 pigmented coating.

Titre : Corrosion protection and thermal functions of carbon-filled silicone coatings for steel substrates Type de document : texte imprimé Auteurs : K. Maruthan, Auteur ; M. Selvaraj, Auteur ; P. Jayakrishnan, Auteur Année de publication : 2005 Article en page(s) : p. 273-276 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : During the last two decades, research work has shown that electrically conductive coatings can also be used to inhibit the corrosion of metals. Nickel flake pigments show a slight advantage over shperical pigments by achieving conductivity through particle-to-particle contact at much lower pigment loading percentages. Similarly, for a conductive nickel flake coating system to protect the metals from different environments relies upon the resin system in the composition.
