Novel acrylamide based curing agents for water borne coatings / Niranjan Patel in PAINTINDIA, Vol. LIV, N° 7 (07/2004)

[article]  inPAINTINDIA > Vol. LIV, N° 7 (07/2004) . - p. 73-84 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.

UV curable aqueous dispersions for wood coatings / Z. Jeffrey Wang in PAINTINDIA, Vol. LIV, N° 7 (07/2004)

[article]  inPAINTINDIA > Vol. LIV, N° 7 (07/2004) . - p. 87-90 Titre : UV curable aqueous dispersions for wood coatings Type de document : texte imprimé Auteurs : Z. Jeffrey Wang, Auteur ; Jo Ann Arceneaux, Auteur ; Jodi Hall, Auteur Année de publication : 2004 Article en page(s) : p. 87-90 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Aqueous dispersions of UV curable resins have been prepared and evaluated. The physical and rheological properties of these dispersions have been determined, and the performance of these dispersions in various wood coating systems has been studied. Coatings based on these dispersions have faster UV cure speed, better surface hardness, and better flexibility compared with coatings based on undispersed resins. These coatings also have excellent solvent and water resistance. Moreover, one of the sprayable waterborne wood coatings gives tackfree before cure properties.
