Title (EN) FINISHING COMPOUND SUITABLE FOR AN ACOUSTIC SUPPORT
(FR) ENDUIT DE FINITION CONVENANT POUR SUPPORT ACOUSTIQUE
Abstract:
(EN) The subject of the present invention is a finishing compound having acoustic properties and comprising, in percentage by weight relative to the total weight of the product, at least - 25 to 80% of water; - 0.1 to 5% of thickener; - 0.01 to 0.8% of dispersant; 10 to 60% of monogranular filler, the D50 of which is greater than or equal to 100 µm; - 0.5 to 6% of binder; and that does not comprise a foaming agent; and that has an air permeability after evaporation of the water between 800 and 6000 mks Rayls.
(FR) La présente invention a pour objet un enduit de finition ayant des propriétés acoustiques et comprenant en pourcentage en poids par rapport au poids total du produit, au moins - 25 à 80 % d'eau; - 0,1 à 5 % d'agent épaississant; - 0,01 à 0,8 % d'agent dispersant; 10 à 60 % de charge monogranulaire dont le D50 est supérieur ou égal à 100 μm; - 0,5 à 6 % de liant; et ne comprenant pas d'agent moussant; et présentant une perméabilité à l'air après évaporation de l'eau comprise entre 800 et 6000 mks Rayls.
