Catalytic curing of industrial OEM coatings - Part I / D. S. Hardas in PAINTINDIA, Vol. XLV, N° 6 (06/1995)
[article]
Titre : Catalytic curing of industrial OEM coatings - Part I Type de document : texte imprimé Auteurs : D. S. Hardas, Auteur ; K. S. Samuel, Auteur Année de publication : 1995 Article en page(s) : p. 21-26 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Peinture Durcissement 'Formation film' 'Amine polymère' Réticulation Polyol Catalyseur Index. décimale : 667.9 Revêtements et enduits Résumé : The importance of catalysts in surface coatings is immeasurable. Catalysts are widely used in the synthesis of coating polymers like alkyds, aminos, silicons, etc, and pigments like copper phtalo-cyanines, quinacridones, perylenes, etc. Their use in the curing of coatings results in not only the product improvement but energy saving and low VOC. the scope of this review paper is to highlight the important aspects of catalysts in industrial OEM coatings.

Titre : Merits and demerits of CAB as a pigment dispersing vehicle in automotive coatings Type de document : texte imprimé Auteurs : K. S. Samuel, Auteur ; Henry Sequeira, Auteur Année de publication : 2000 Article en page(s) : p. 43-48 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The automotive OEM sector is always on the look-out for a better proposition in order to cater to the customers needs. The industry is always demanding certain requirements from the paint manufacturer to comply to the market demands. The paint manufacturer thus is always on the look-out for newer systems, which can outdo the conventional systems, and equip himself to meet the propositions of the industry. One such option is the use of Cellulose Acetate Butyrates (CAB). CABs are known to the paint manufacturer and are used extensively in lacquers and varnishes for their excellent drying properties, durability and as an additive for imparting certain properties. The use of CABs as pigment dispersion media stands relatively unexploited. The feasibility of CABs in the dispersion process requires an in-depty analysis. An approach to this concept has been made in the paper. The paper contains an analysis of CAB as a pigment dispersion media, its merits and demerits as against the conventional dispersing media.

[article]
Titre : A review of liquid crystalline polymers Type de document : texte imprimé Auteurs : K. S. Samuel, Auteur Année de publication : 1995 Article en page(s) : p. 19-24 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Polymère 'Cristal liquide' 'Article synthèse' 'Propriété rhéologique' Viscosité 'Alkyde résine' Greffage 'Peinture haute teneur solide' 'Acrylique dérivé polymère' Index. décimale : 667.9 Revêtements et enduits Résumé : Crystalline solids have three dimensional order while liquids and gasses are disordered. Liquid crystalline (LC) materials have intermediate degrees of order and have been known since 1888. Among the structures that tend to form liquid crystals are molecules containing a sequence of two or more aromatic rings connected in the para position by rigid or semi-rigid linkages. Such structures are called "mesogenic" and LC materials are called "mesomorphous". Recently, there has been widespread interest in the properties of polymers that contain LC regions in solution and/or in the bulk polymer. The mesogenic groups that form the LC regions can be in the main chain [1] or in side chains [2]. LC regions impart a variety of unusual and potentially useful properties to polymers. Such properties of these novel polymers are exploited in coating industries. Note de contenu : - CLASSIFICATION OF LCPS
