Fire retardant coatings for electric cables / N. K. Saxena in PAINTINDIA, Vol. XLIX, N° 2 (02/1999)

[article]  inPAINTINDIA > Vol. XLIX, N° 2 (02/1999) . - p. 35-37 Titre : Fire retardant coatings for electric cables Type de document : texte imprimé Auteurs : N. K. Saxena, Auteur ; S. Singh, Auteur ; T. P. Sharma, Auteur Année de publication : 1999 Article en page(s) : p. 35-37 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Matériau  revêtement'  'Protection  feu'  'Retardateur  flamme'  'Câble  électrique' Index. décimale : 667.9 Revêtements et enduits Résumé : Fire Retardant Intumescent Coatings have been studied for fire protection of PVC Insulated Power Cables. The fire performance of coated cables has been assessed by employing standard methods. The coatings were found quite effective in reducing the burning behaviour ofpower cables. Significant improvement in circuit failure time is noted in coated cable specimens. Note de contenu : - EXPERIMENTS - Preparation and application of coating - Evaluation of cable coating - Preparation of specimen - Evaluation procedure as per IEC-331 Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12925 [article]

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]

Water soluble cathodic electrodepositable coating compositions / S. Singh in PAINTINDIA, Vol. LII, N° 1 (01/2002)

[article]  inPAINTINDIA > Vol. LII, N° 1 (01/2002) . - p. 35-40 Titre : Water soluble cathodic electrodepositable coating compositions Type de document : texte imprimé Auteurs : S. Singh, Auteur ; P. K. Kamani, Auteur ; M. C. Shukla, Auteur Année de publication : 2002 Article en page(s) : p. 35-40 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Esterified epoxy-amine adducts with linseed fatty acids were prepared by reacting epoxy-amine-adduct and linseed fatty acids in different proportions. The used epoxy-amine adduct was synthesized from epoxy resin and diethanol amine in molar ratio 1:1. The pigmented coating compositions for cathodic electrodeposition were prepared by using different esterified epoxy-amine adducts with linseed fatty acids, separately. Film properties of cathodic electrodeposited coating compositions were studied and it was found that the coating compositions having 10% and 15% esterified epoxy- amine adducts showed good film properties.
