Properties such as drying time, hardness, adhesion, flexibility, gloss, skinning tendency, impact resistance and chemical resistance of the blends were studied. Ketonic resin was blended with alkyd resin, and a significant improvement in adhesion, hardness, gloss , storage stability, acid resistance and drying time was achieved over that of the alkyd resin .

Low cost multipurpose coatings from alkyd-ketonic blends / Vilas D. Athawale in PAINTINDIA, N° spécial (01/2003)

[article]  inPAINTINDIA > N° spécial (01/2003) . - p. 41-48 Titre : Low cost multipurpose coatings from alkyd-ketonic blends Type de document : texte imprimé Auteurs : Vilas D. Athawale, Auteur ; A. V. Chamankar, Auteur Année de publication : 2003 Article en page(s) : p. 41-48 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Reports a comprehensive study of the effects of blend ratios (aliphatic alkyd and cyclohexanone formaldehyde resins) on coating properties. Solvent and drier systems used for preparation of blends are also included in the present work. The properties studied were hardness, adhesion, flexibility, gloss, storage stability, impact resistance, chemical resistance and drying time. A blend ratio of 50:50 (w/w) aliphatic alkyd-ketonic resins showed a significant improvement in adhesion, hardness, gloss, storage stability and acid resistance. Note de contenu : - Synthesis of 65% oil length aliphatic alkyd resin - Specification of ketonic ( cyclohexanone formaldehyde) resin - The percent of driers used were aas per the resin solids - Chemical resistance Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12110 [article]

Commercial method was adopted to prepare the blends. Properties such as drying time, hardness, adhesion, flexibility, gloss, skinning tendency, impact resistance and chemical resistance of the blends were studied. It was observed that, when ketonic resin was blended with alkyd resin, a significant improvement in adhesion, hardness, gloss, storage stability, acid resistance and drying time was achieved over that of the alkyd resin. Note de contenu : - Experimental : - Synthesis and characteristics of the resins - Solvent system and driers used for the blends - Determination of film properties - Results and discussion : - Effect on drying - Effect on the hardness - Effect on gloss - Effect on the adhesion and flexibility - Effect on the storage stability - Effect on the impact resistance Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12954 [article]

Superior coatings with alkyd and ketonic resin blends / Vilas D. Athawale in EUROPEAN COATINGS JOURNAL (ECJ), N° 11/00 (11/2000)

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 11/00 (11/2000) . - p. 57-64 Titre : Superior coatings with alkyd and ketonic resin blends Type de document : texte imprimé Auteurs : Vilas D. Athawale, Auteur ; A. V. Chamankar, Auteur Année de publication : 2000 Article en page(s) : p. 57-64 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Because of their low cost and good compatibility with a wide variety of other polymers, alkyd based coatings are used in a large variety of applications. However, to improve their performance, the alkyd resins can be blended with ketonic resins. Such blends were analysed by SEM, and tested for their shelf life. Improvements in properties such as drying time, hardness, adhesion, flexibility, gloss, skinning tendency, impact resistance and chemical resistance were studied. Note de contenu : - Blending to improve the performance of alkyds - Preparation of the blends - Simultaneous oxygen activation and solvent evaporation effect fast drying - Improvement in hardness and gloss - Increased adhesion - Ketonic resins serve as stability additives - Water resistance decreases with increasing ketonic concentration - High impact resistance due to compatibility Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11058 [article]
