Thermoset powder coatings utilizing carboxylic acid functional polyester resins cared with epoxide-functional acrylate polymers have been evaluated and characterized. Modification of the composition and molecular weight of either component influences the physical properties of formulated powder coating. The behavior of these coatings during the cure process has been investigated and compared with polyester/TGIC. systems.

Novel ambient temperature curable two-component waterborne silicone-acrylic coating / Nobuo Harui in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 70, N° 880 (05/1998)

[article]  inJOURNAL OF COATINGS TECHNOLOGY (JCT) > Vol. 70, N° 880 (05/1998) . - p. 73-77 Titre : Novel ambient temperature curable two-component waterborne silicone-acrylic coating Type de document : texte imprimé Auteurs : Nobuo Harui, Auteur ; Tetsuro Agawa, Auteur Année de publication : 1998 Article en page(s) : p. 73-77 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 667.9 Revêtements et enduits Résumé : Waterborne coatings are composed of resins containing hydrophilic functional groups. These groups usually remain in the coating film and can adversely affect film properties such as weatherability and resistance to water and alkali. We have developed a novel ambient temperature curable waterborne two-component system, in which the hydrophilic functional groups are consumed by the crosslinking reaction. The new coating system consists of a waterborne acrylic resin containing both tert-amino and carboxylic acid groups and a hardener containing both epoxy and alkoxysilyl groups. The waterborne silicone acrylic coatings provide superior film properties even if the acrylic resin has relatively low functional group content.In this paper we describe the crosslinking reaction mechanism and film properties using some acrylic resin types and paint formulations as examples Note de contenu : -EXPERIMENTAL MATERIALS : Model A od Acrylic resin solution type - Model B of WB resin type - Model C of acrylic resin solutio, type(used only for FTIR analysis) - Model D of WB (used only for FTIR analysis) - RESULTS AND DISCUSSION : Crosslinking mechanism - Film properties Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=18004 [article]
