A paint containing: a dispersing medium; a binder; a pigment; a filler; an additive; and at least one agent capable of trapping formaldehyde selected from the group consisting of a compound including an active methylene, a compound including a tannin, and a compound including an amide. In addition, a method for reducing the amount of formaldehyde in the air inside a building by applying the paint to an inner surface of the building.

Film-forming composition including an agent capable of trapping formaldehyde

A multilayer wall covering includes: (a) a support layer formed by an organic polymer foam having an open porosity of between 0.50 and 0.995, or by a viscose fiber nonwoven having a mass per unit area of between 150 g/m2 and 500 g/m2, (b) a surface layer formed by a glass textile, having a static air flow resistance, measured according to the standard ISO 9053, of between 105 N&#xb7;s&#xb7;m&#x2212;4 and 106 N&#xb7;s&#xb7;m&#x2212;4, (c) at the interface between the support layer (a) and the surface layer (b), a discontinuous adhesive layer having a mass per unit area of between 17 and 60 g/m2. There is also provided a process including the use of such a covering for improving both the acoustic and the thermal comfort of a room, and two processes for manufacturing such a covering.

Wall covering for thermal and acoustic comfort

The present invention relates to a glass strand having a coating including a polymer chosen from vinyl acetate/vinyl chloride copolymers, polyvinyl chloride and polyvinylidene chloride, and a silane of formula (I).

Glass strand provided with a polymer-based coating and screen comprising said strand

A multilayer sound-absorbing covering includes (a) a support layer made of an organic polymer foam having an open porosity between 0.50 and 0.995, (b) a surface layer formed by a glass textile, having a static air flow resistance, measured according to the standard ISO 9053, between 105 N&#xb7;s&#xb7;m-4 and 106 N&#xb7;s&#xb7;m-4, (c) at the interface between the support layer (a) and the surface layer (b), a discontinuous adhesive layer having a surface density between 17 and 60 g/m. There is also provided a process for manufacturing such a covering and the use of such a covering for improving the acoustic comfort of a room or of a building.

Acoustic absorbent wall coating

A multilayer sound-absorbing covering includes (a) a support layer made of a nonwoven based on organic fibers having a tranverse multilobal cross section, (b) a surface layer formed by a glass textile, having a static air flow resistance, measured according to the standard ISO 9053, between 10N&#xb7;s&#xb7;mand 10N&#xb7;s&#xb7;m, (c) at the interface between the support layer (a) and the surface layer (b), a discontinuous adhesive layer having a surface density between 17 and 60 g/m. There is also provided a process for manufacturing such a covering and to the use of such a covering for improving the acoustic comfort of a room or of a building.

The present invention relates to a film-forming composition intended to be applied to an inner surface of a building which includes an agent capable of trapping formaldehyde chosen from compounds comprising active methylene(s), tannins and amides. Another subject matter of the present invention is the use of said film-forming composition in reducing the amount of formaldehyde in the air inside a building.
