Titre : Wall finishes based on novel short oil rosinated alkyd Type de document : texte imprimé Auteurs : Bharati W. Phate, Auteur ; Bhalchandra B. Gogte, Auteur Année de publication : 2005 Article en page(s) : p. 71-76 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Conventional alkyd resins utilized 40-50% phthalic anhydride in short oil compositions. We are interested in developing resins based mainly on vegetable resources rather than the petroleum products like phthalic anhydride. We have developed a short oil alkyd specifically using less proportion of anhydride & polyol, which is having all desirable properties for wall finishes. For controlling the activity of maleic anhydride sizable proportion of rosin has been used. The use of benzoic acid and rosin, which acts as chain stopper and regulates the polymerization at optimum level. Steady and slow growth of polymer reduced the chances and risk of gelation. We successfully incorporate acrylic and alkyd polymer in formulation of wall finish. Composition based on new alkyd and blends of alkyd with acrylics have been tried. The physicochemical properties of wall finish and their film properties have been tested and compared with standard brands of commercially available wall finishes. The novel wall finishes are technically and economically feasible propositions. Note de contenu : - Characteristics of ideal wall finish
