Smart coatings : Current research and applications / Melrina Mascarenhas in PAINTINDIA, Vol. LV, N° 12 (12/2005)

[article]  inPAINTINDIA > Vol. LV, N° 12 (12/2005) . - p. 55-66 Titre : Smart coatings : Current research and applications Type de document : texte imprimé Auteurs : Melrina Mascarenhas, Auteur Année de publication : 2005 Article en page(s) : p. 55-66 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Paint research is increasingly focusing on aspects of paint other than the traditional roles of protection and decoration. One such area of interest is 'Smart' Coatings. Smart coatings are structured, functional systems that can sense and react to specific external conditions. Sensor coatings, self-healing coatings, Self-assembling nanoscopic coatings are some of the coatings with smart functions reviewed in this paper. Nanotechnology and interdisciplinary materials science are the major drivers in the structuring of these innovative functional paints. It is therefore no surprise that Smart Coatings are gaining worldwide interest both in academia and industry.

Volatile Organic Compounds (VOCs) in paints and its reduction / Asim K. Jana in PAINTINDIA, Vol. LV, N° 12 (12/2005)

[article]  inPAINTINDIA > Vol. LV, N° 12 (12/2005) . - p. 67-72 Titre : Volatile Organic Compounds (VOCs) in paints and its reduction Type de document : texte imprimé Auteurs : Asim K. Jana, Auteur ; Amit Jain, Auteur ; Jatinder Kumar, Auteur Année de publication : 2005 Article en page(s) : p. 67-72 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The basic components of the paints are pigments, binders, film formers, additives and solvents. Thinning solvents are sometimes added before application. Many of the chemicals in conventional paint are known or suspected to be carcinogens. These paints and solvents contain Volatile Organic Compounds (VOC) such as xylene, toluene, methyl or ethyl ketone, etc of concentration up to 550 gm/liter and play a great role in air pollution. VOCs also react with NOx in the atmosphere and give rise to ground level ozone and photochemical smog which are harmful. Environmental pollution aspects of the conventional paints and new developments in paint technology to reduce pollution have been discussed. The potential alternatives are reducing the amount of solvents in the formulation to make high solid content paint, substitution of VOCs with less damaging solvents such as water based paints and the substitution of aromatic with aliphatic hydrocarbon solvents. Coating the metal items using powder technology, or the use of ultraviolet light to promote polymerization of the coating film are also the emerging technologies.

Photochromism / Shilpi Sanghi in PAINTINDIA, Vol. LV, N° 12 (12/2005)

[article]  inPAINTINDIA > Vol. LV, N° 12 (12/2005) . - p. 73-90 Titre : Photochromism Type de document : texte imprimé Auteurs : Shilpi Sanghi, Auteur ; Atri Rungta, Auteur ; V. C. Malshe, Auteur Année de publication : 2005 Article en page(s) : p. 73-90 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Photochromism is the reversible change in the absorption spectrum of a molecule on irradiation by light of certain wavelength. This phenomenon is observed in various compounds. Two types of photochromic polymer systems exist, those in which photo chrome is incorporated into a polymer binder in the form of a solid solution and the others inherently photochromic polymers. This article attempts to review the properties needed forany class of photo-chromic compounds and the mechanisms responsible for the photo chromic effect and also gives an account of the synthesis, structural and physical properties of fulgides, benzopyrans, naphthopyrans, spironaphthoxazines, spirobenzopyrans and their derivatives. The chiral photochromic Liquid Crystalline (LC) polymers are of great importance because they combine the properties of LC polymers and photochromic polymers. The article also covers the extensive applications of the photo chromic polymer systems in the field of ophthalmics, printing, textiles and in optical data storage.

The performance of paint coating on galvanized steel in coil coating line / G. D. Patange in PAINTINDIA, Vol. LV, N° 12 (12/2005)

[article]  inPAINTINDIA > Vol. LV, N° 12 (12/2005) . - p. 91-102 Titre : The performance of paint coating on galvanized steel in coil coating line Type de document : texte imprimé Auteurs : G. D. Patange, Auteur Année de publication : 2005 Article en page(s) : p. 91-102 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Paint coatings are specialty products, which are used to give long term protection under a broad range of corrosive conditions, extending from atmospheric exposure to full immersion in strongly corrosive solutions. A paint coating provides them little strength, yet they protect galvanized steel, so that the strength and integrity of steel can be maintained. The quality of paint coated hot-dip galvanized (HDGJ steel sheets against aggressive environments depends on several factors linked to galvanizing, tension regulation at various sections, concentration of alkaline bath and chemical conversion coating bath, hydrogen evolution and baking temperature of primer and topcoat ovens. Each component gives a contribution to the final anticorrosive performance of the coated product.
