When the TiO2 surface was fully covered with the block copolymers, the colloidal stability of the TiO2 dispersions at typical curing temperatures was significantly improved because of the formation of a steric layer around the pigment particles. As a result, powder coatings with excellent flow, high gloss, and low haze values were obtained. Because of the high affinity of the dispersants for the TiO2 surface, pretreatment of the pigments with the block copolymers was not necessary. At full pigment surface coverage, the chain length of the stabilizing polymer had little effect on the performance of the dispersants used.

Titre : Waterborne epoxy protective coatings for metal Type de document : texte imprimé Auteurs : F. L. Duivenvoorde, Auteur Année de publication : 2002 Article en page(s) : p. 63-72 Note générale : Bibliogr. Langues : Américain (ame) Tags : Dispersion aqueuse Amidoamine polymère Durcissant Epoxyde résine Formulation Peinture deux constituants eau anticorrosion Revêtement Index. décimale : 667.9 Revêtements et enduits Résumé : Recent enhancements in waterborne resin system polymers as well as the way they are formulated have produced paints with a set of barrier properties that are superior to their standard solventborne analogs. New generation waterborne epoxy and curing agent dispersions, and the paints formulated from them, have been introduced with changes from older generation waterbornes. These changes include (1) totally nonionically dispersed paints in place of the older ionically dispersed types, (2) quicker coalescing, mutually soluble epoxy/amine vehicle resins rather than the former slow coalescing, highly branched epoxylamine systems, and (3) utilization of stable, water compatible additives and fillers that complement the nonionic epoxylamine resin vehicles. In this paper, the success of these implemented technology changes is demonstrated by comparing the performance properties of the new generation with an industry standard epoxy/polyamide solventborne paint.
