Title
(EN) SILICONE-BASED BARRIER COMPOSITIONS
(FR) COMPOSITIONS BARRIÈRE À BASE DE SILICONE
Abstract
(EN)
A liquid applied, silicone-based air and water barrier composition and its use as a silicone-based air and water barrier, which is preferably vapour permeable for the construction industry, which liquid applied, silicone-based air and water barrier composition has a shelf-life of ≥ 9 months. The composition comprises (i) a crosslinked polysiloxane dispersion (c) a surfactant and (d) water; (ii) a combination of rheology modifiers and at least one of the following ingredients: (iii) one or more fillers and/or (iv) one or more stabilizers.
(FR)
L'invention concerne un liquide appliqué, une composition barrière à l'air et à l'eau à base de silicone et son utilisation comme une barrière à l'air et à l'eau à base de silicone, qui est de préférence perméable à la vapeur pour l'industrie de la construction, laquelle composition barrière à l'air et à l'eau à base de silicone a une stabilité au stockage de ≥ 9 mois. La composition comprend (i) une dispersion de polysiloxane réticulé (c) un tensioactif et (d) de l'eau; (ii) une combinaison de modificateurs de rhéologie et d'au moins l'un des ingrédients suivants: (iii) une ou plusieurs charges et/ou (iv) un ou plusieurs stabilisants.
