[article]  inPAINTINDIA > Vol. LVI, N° 1, Sup (01/2006) . - p. 121-130 Titre : A focus on electrodeposition coatings - The green technology with green future Type de document : texte imprimé Auteurs : Chintan Patel, Auteur ; A. K. Dighe, Auteur Année de publication : 2006 Article en page(s) : p. 121-130 Note générale : Bibliogr. 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. In this paper attempts have been made to enlighten various aspects of this technique along with future prospects.

Novelty finishes based on acid functional acrylic copolymers / D. A. Raval in PAINTINDIA, Vol. LI, N° 2 (02/2001)

[article]  inPAINTINDIA > Vol. LI, N° 2 (02/2001) . - p. 35-40 Titre : Novelty finishes based on acid functional acrylic copolymers Type de document : texte imprimé Auteurs : D. A. Raval, Auteur ; A. K. Dighe, Auteur ; R. J. Parmar, Auteur Année de publication : 2001 Article en page(s) : p. 35-40 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Novelty finishes like hammertone, stipple and multicolour were prepared from acid functional acrylic copolymers. These finishes were based on these copolymer resins of thermoplastic and thermosetting types. Both the types of copolymers were neutralised with triethylamine and made water compatible with the help of cosolvent butylcellosolve. Pigments and additives were added accordingly in the preparation of these novelty finishes. Special application techniques were used to apply these coatings (finishes). Thus an attempt was made for the preparation of ecofriendly novelty finishes. Note de contenu : - Materials and methods - Preparation of hammertone finishes - Preparation of stipple finishes (paints) - Preparation of multicolour finishes (paints) - Application of novelty finishes (paints) - Characterization of the novelty finishes (paints) - Nature of resin used in finishes - Type of pattern - Viscosity - Colour - Gloss - Films and their evaluation - Mechanical properties - Detergent resistance - Package stability (shelf life) of the finishes Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12532 [article]

Polyurethane-Acrylic (PU-AC) hybrid dispersion: the mechanism, processing and an overview / Ashish Patel in PAINTINDIA, Vol. LVI, N° 11 (11/2006)

[article]  inPAINTINDIA > Vol. LVI, N° 11 (11/2006) . - p. 63-67 Titre : Polyurethane-Acrylic (PU-AC) hybrid dispersion: the mechanism, processing and an overview Type de document : texte imprimé Auteurs : Ashish Patel, Auteur ; A. K. Dighe, Auteur ; Chintan Patel, Auteur ; Kalpesh Patel, Auteur Année de publication : 2006 Article en page(s) : p. 63-67 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Polyurethane dispersions are widely used in coating industries but in some application areas they are bound by the cost factor although it has very goodperformance properties. In order to achieve a true price/performance balance: Polyurethane - Acrylic hybrids are appropriate. Hybridization of polyurethane -acrylics are done by various mechanisms to achieve average smaller particle size, narrower molecular weight distribution and a particulate morphology.

Langues : Anglais (eng) Catégories : Copolymères en émulsion Latex Résistance aux taches Revêtements:Peinture Taille des particules Index. décimale : 667.9 Revêtements et enduits Résumé : Polymer latexes with bimodal particle size distribution can be prepared by inteoducing small amount of a second seed of polymer particle during semicontinuous emulsions polymérization. The particle size of these miniemulsions depends essentially on th shear force exerted when the monomers are dispersed in water. Incorporating strong acid into a polymer bacbone of bimodal copolymer provides an improvement in stain blocking, bloc resistance, hiding and shear stability.
