[article]  inPAINTINDIA > Vol. LIV, N° 1 (01/2004) . - p. 41-44 Titre : Comparative study and film performance of epoxy polyester and epoxy polyester hybrids powder coating Type de document : texte imprimé Auteurs : Vipin Shukla, Auteur ; Madhu Bajpai, Auteur ; Mudit Goyal, Auteur ; Dharmendra Singh, Auteur ; Mahendra Singh, Auteur Année de publication : 2004 Article en page(s) : p. 41-44 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Thermally curable powder coatings are widely used for coating metallic components due to the unique combination of technological, environmental and economic benefits. This paper describes various physical and chemical properties of different powder coating films like epoxy, pure polyester and epoxy polyester hybrid. In this paper an attempt is made to correlate the properties of different powder coating films and also the influence of type of resins are discussed.

Superior coatings from epoxy cresol novolac resin / Mudit Goyal in PAINTINDIA, Vol. LII, N° 6 (06/2002)

[article]  inPAINTINDIA > Vol. LII, N° 6 (06/2002) . - p. 39-44 Titre : Superior coatings from epoxy cresol novolac resin Type de document : texte imprimé Auteurs : Mudit Goyal, Auteur ; Mahendra Singh, Auteur ; Dharmendra Singh, Auteur ; S. Singh, Auteur ; Vipin Shukla, Auteur Année de publication : 2002 Article en page(s) : p. 39-44 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Bisphenol-A epoxy resin have certain inherent drawbacks. the limitation could be overcome by replacing them with multifunctional epoxy resins such as epoxy phenol novolac (EPN) and epoxy cresol novolac (ECN) resins. Synthesis and characterization of EPN and ECN has been discussed. ECN resin were observed to be much superior so that a comprehensive study was made of the various coating properties such as drying time, hardness, adhesion, gloss, flexibility, skinning tendency, corrosion, impact-resistance and chemical resistance of cresol novolac epoxy cured with polyamide resin. Note de contenu : - METHODS : Synthesis of novolac resins - Synthesis of epoxy novolac resins - DETERMINATION OF EPOXY EQUIVALENT WEIGHT (EEW) : Reagents - Procedure - Calculation - EVALUATION OF FILM CHARACTERISTICS - RESULTS AND DISCUSSION : Drying time - Hardness - Gloss - Salt-spray test - Impact resistance Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12363 [article]
