Titre : Grafting epoxy resins Type de document : texte imprimé Auteurs : Randhir Parmar, Auteur ; Kalpesh Patel, Auteur ; Niranjan Patel, Auteur ; Jayant S. Parmar, Auteur Année de publication : 2004 Article en page(s) : p. 32-37 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Waterborne coatings - Waterbornes industrial coatings are the key area of interest for researchers because of industrial pollution, industrial safety and stringent legislations. Epoxy resins of higher molecular weight were grafted with acrylic monomers, neutralized and reacted with N-butoxymethacrylamide to generate curing site on its backbone and give water compatibility. Sets of self-curing coating composition were prepared and their physico-chemical charactéristics such as particle size and viscosity were measured. The performance properties of the cured films reveal their potential applications as high performance coating binders for waterborne coatings.

Titre : Novel acrylamide based curing agents for water borne coatings Type de document : texte imprimé Auteurs : Niranjan Patel, Auteur ; Randhir Parmar, Auteur ; Tushar P. Patel, Auteur ; Jayant S. Parmar, Auteur Année de publication : 2004 Article en page(s) : p. 73-84 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The water-borne acrylamide based curing agents (WACAs) were synthesized using various proportions of methylmethacrylate (MMA), formaldehyde and methanol. These curing agents were blended with water borne hydroxyl functional acrylic resins (WHFAC) and the resulting compositions were applied on test panels. The coating compositions were also made from conventional hexamethoxy methyl melamine (HMMM) resin for comparison study. All the coated panels were stored at 150°C for 15 mins. The WACAs were characterized for their physical properties, IR-spectra and molecular weight by GPC. The coated films were also characterized for their mechanical properties, chemical, solvent, and water resistance and for thermal properties by TGA and DSC. The results indicate that comparable coating performance is achieved for some of the coating compositions under study.
