Hybrid and Gemini surfactants as tools to paint chemists / Seema S. Otari in PAINTINDIA, Vol. L, N° 2 (02/2000)

[article]  inPAINTINDIA > Vol. L, N° 2 (02/2000) . - p. 33-42 Titre : Hybrid and Gemini surfactants as tools to paint chemists Type de document : texte imprimé Auteurs : Seema S. Otari, Auteur ; V. C. Malshe, Auteur Année de publication : 2000 Article en page(s) : p. 33-42 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Surfactants (short for surface active agents) are chemical compounds generally consisting of a hydrocarbon portion (which interacts very weakly with water molecule in an aqueous environment and squeezes out of water ; hence the chain is usually termed as hydrophobic tail) andpolar or ionic portion (usually called head group ; however, interacts strongly with water via dipole- dipole or ion-dipole interactions an is solvated, therefore called hydrohilic). Note de contenu : - Classification of surfactants according to nature of hydrophilic or head group - Terms involved in science of surfactant : Surface tension – Spreading or wetting coefficient – Surface defect – Critical micelle conc. (CMC) – Krafft temperature - Certain characteristic features and mode of action of surfactants - Importance : Outstanding properties of silicone surfactants - Outstanding properties of fluoro surfactants - Outstanding properties of Gemini surfactants - Silicone surfactants : Structure – Preparation – Properties – New developments - Fluoro surfactants : Structure – Preparation - Properties – New developments - Gemini surfactants : Structure – Preparation – Properties – New developments Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12704 [article]

Physical and chemical studies of silicone resin based surface coatings - Revolutionary products / Y. C. Nijhawan in PAINTINDIA, Vol. L, N° 2 (02/2000)

[article]  inPAINTINDIA > Vol. L, N° 2 (02/2000) . - p. 43-46 Titre : Physical and chemical studies of silicone resin based surface coatings - Revolutionary products Type de document : texte imprimé Auteurs : Y. C. Nijhawan, Auteur ; R. Dixit, Auteur Année de publication : 2000 Article en page(s) : p. 43-46 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : In the present Indian scenario of paint industries only one of the Indian industries has introduced cost effective silicone coatings based on silicone binder, the first of its kind in India to protect civil structures from extrême weather conditions. The present studies are based on research and development of these products. The use of these coatings enhances the life and durability of surfaces and possesses all the properties of high standard coatings. Note de contenu : - Experimental : Exterior surface coatings – Interior surface coating – Transparent surface coatings – Protective heat resistant surface coatings Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12705 [article]

Water based screen inks / V. D. Sawant in PAINTINDIA, Vol. L, N° 2 (02/2000)

[article]  inPAINTINDIA > Vol. L, N° 2 (02/2000) . - p. 79-80 Titre : Water based screen inks Type de document : texte imprimé Auteurs : V. D. Sawant, Auteur Année de publication : 2000 Article en page(s) : p. 79-80 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Presently because of heavy pollution in cities of India it is necessary to control it. Coating Industries is one of the pollution industry. In paint industry efforts are being taken to manufacture solvent-less and high solid paints and water based paints to minimise the pollution. Here we discuss water based screen inks so as to minimise the pollution due to solvent vapours evolved during manufacturing or printing.
