Title (EN) GRANULATED HYDROPHOBIC ADDITIVE FOR GYPSUM COMPOSITIONS
(FR) ADDITIFS HYDROPHOBES GRANULES POUR COMPOSITIONS DE GYPSE
Abstract: front page image
(EN)A hydrophobic gypsum composition is provided which contains gypsum, a granulated hydrophobing additive and a pH effecting additive in an amount sufficient to maintain the pH of the composition between 8 and 12.5 in the presence of water. The granule contains an organopolysiloxane having Si bonded hydrogen, a water soluble or water dispersible binder, and a carrier, preferably gypsum or a stearate salt; in an amount sufficient to hydrophobe the gypsum. The pH effecting additive is preferably lime but may be any appropriate additive.
(FR)L'invention concerne une composition de gypse hydrophobe contenant du gypse, un additif d'hydrophobisation granulés, et un additif à action pH en quantité suffisante pour maintenir le pH de la composition entre 8 et 12,5 en présence d'eau. La granule contient un organopolysiloxane présentant de l'hydrogène lié à du silicium, un liant pouvant se disperser dans de l'eau ou hydrosoluble, et un support, de préférence du gypse ou un sel stéarate en quantité suffisante pour rendre le gypse hydrophobe. L'additif à action pH est, de préférence, de la chaux, mais ce peut être également tout additif approprié.
