Titre : High performance hybrid organic inorganic coatings Type de document : texte imprimé Auteurs : Christian Simon, Auteur ; Ferdinand Mannle, Auteur Année de publication : 2006 Article en page(s) : p. 97-102 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Organic-inorganic hybrid coatings have recently shown new and promising properties. Applications may be found in the area of protective coatings, e.g. corrosion resistant, scratch and wear resistant materials combined with high photostability and in the area of materials with improved barrier properties as well. The industrial coating market is undergoing substantial changes due to environmental regulations, where cost-effective nanoparticle modified coatings could represent competitive products. This paper presents the applications of polybranched hybrid organic-inorganic coatings. Nanoparticle based dispersions made by sol-gel method have been prepared and the particles surface was modified to suit mixing with a variety of polymer materials. By a suitable choice of raw materials, stabilisers, coating forming additives and other types of additives could be prepared. Such stabilisers or other additives give a broader application range than what is the case for known mono functional stabilisers and can be used in lacquers, paints, curable plastics and thermoplastics. The various applications of these products will be illustrated for wear resistance, photostability, barrier layers and additives for retarding degradation. Note de contenu : Introduction

Titre : Superdurable powder coatings - a novel alternative for exterior architectural finishing Type de document : texte imprimé Auteurs : B. P. Mallik, Auteur Année de publication : 2006 Article en page(s) : p. 103-114 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Skylines of today's metros are increasingly dominated by high rise buildings and commercial complexes with distinctive look and appeal that epitomize the marvel of modern design concepts. Building designers are increasingly using varieties of innovative materials for structural glazing on architectural facades starting from pre-coated metals, anodized aluminium panels, ceramic tiles, glass, composite panels etc. with wide array of colours to create unique look and identity. As a result the contemporary look of commercial office complexes, buildings, corporate houses, shopping plaza is taking a backseat and being transformed with modern architectural facelift. The challenge is to ensure that these structural glazings retain their original colour, appearance and gloss throughout their lifespan. Superdurable powder coatings are becoming the lucrative choices for designer's in the structural glazing industry for architectural facades, door and window frames etc because of their availability in wide array of shades in both solids as well as metallic colour having outstanding exterior durability, colour retention and overall corrosion protection. This paper attempts to highlight the merits of superdurable powder coating and relevant issues from the perspective of designing a viable coating option for the exterior architectural finishing in relation to others.

Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Compliance with today's government regulations for reducing air pollution associated with paint application relies upon use of coatings containing less organic solvent (volatile organic compounds or VOCs) as well as application methods that improve transfer efficiencies. High transfer efficiency not only helps meet environmental regulations and cut, costs but also provides a safer work place. Electrodeposition is one of the techniques which are capable to meet these requirements.

Titre : Dry-film biocides- The next generation Type de document : texte imprimé Auteurs : John Gillatt, Auteur Année de publication : 2006 Article en page(s) : p. 169-176 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Of the three main groups of microorganisms that can infect paints, plasters and similar surface coatings it is fungi and algae that are especially problematic after the material has been applied. Fungi, primarily moulds, cause surface disfigurement and actual degradation, whilst algae also detract from the product's aesthetic qualities as well as retaining high levels of moisture with resultant concomitant damage. Exterior surfaces can become infected with both types of organisms and broad-spectrum antifungal/antialgal biocides have been developed to prevent such growths. However, changing legislation relating to the labelling of such biocides, pressure from environmental and consumer groups and revised regulations concerning insulation of buildings have placed greater and greater demands on biocides and have created a need for new products with novel properties. Although such demands represent a significant challenge to the biocide manufacturer it has been possible to meet these requirements.
