Titre : More than skin deep : Easily dispersed dry emulsion protects bulk and surface of cement mixtures Type de document : texte imprimé Auteurs : M. Sari, Auteur ; A. Christmann, Auteur ; M.-C. Grisolet Année de publication : 2010 Article en page(s) : p. 38-43 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Revêtement protecteur Ciment Emulsion sèche Additif hydrofuge Hydrophobisation Tests pénétration Index. décimale : 667.9 Revêtements et enduits Résumé : Concrete protection - A new water repellent additive for cement-based materials is supplied in the form of a dry emulsion which is self-dispersing in water. On both grouting and facade materials, the emulsion product gave much better bulk hydrophobisation than standard water repellents. Its also reduced colour changes after wet/dry cycling and algal growth.

Titre : Surfactant behavior and its influence on the viscosity of associative thickeners solutions, thickened latex dispersions, and waterborne latex coatings Type de document : texte imprimé Auteurs : David M. Mahli, Auteur ; Mark J. Steffenhagen, Auteur ; Lin-lin Xing, Auteur Année de publication : 2003 Article en page(s) : p. 39-51 Note générale : Bibliogr. Langues : Américain (ame) Tags : Acrylique dérivé polymère Hydrophobisation Ethylène oxyde Agent surface Epaississant Adjuvant Viscosité Propriété rhéologique Formulation Peinture émulsion eau Matériau revêtement Index. décimale : 667.9 Revêtements et enduits Résumé : Surfactants, varying in their chemical composition and hydrophobic behavior, are used in the formulation of a waterborne coating. These differences influence their aggregation in micellar structures, their interaction with associative thickeners, and in particular, the synergies present in their competitive adsorptions on the disperse phases in a waterborne coating. Adsorption of HEUR thickeners on latexes and the ability of surfactants to displace them from those surfaces is an important variable in the dispersion's viscosity. With large particle latexes, viscosity increases arise primarily from the network built through the interaction of HEURs with surfactants in the aqueous phase. Fluorescence is used to verify the mechanism by which surfactants enhance associative thickener viscosities. That is best achieved with nonionic surfactants, because of their synergies with large hydrophobe HEURs at low concentration. With decreasing latex particle size the adsorbed species is an important contributor to the dispersion's viscosity through its contribution to the latex's effective volume fraction increase and when the size of the adsorbed HEUR is matched to the separation distances of the latex at 0.25 volume fraction. Achieving controlled shear-thinning behavior in small particle size latex paints with the economic constraints on the amount of HEUR required to obtain 90 KU viscosities are discussed.
