Abstract:
The invention relates to a self-adhesive wall covering comprising a glass textile with a closed structure, consisting of glass fibers and of a water-permeable polymer binder, and an adhesive coating comprising both a pressure-sensitive adhesive (PSA) and a water-activable latent adhesive. The definitive attachment to the wall of this repositionable self-adhesive covering takes place, after hanging, by applying one or more coats of water-based paint.

The invention relates to a process for manufacturing flat glass, comprising: (a) impregnating a glass textile with a molten glass composition, the glass forming the fibers of the glass textile having a softening temperature above that of the glass forming the molten glass composition, said step (a) comprising (a1) impregnating the glass textile with a glass frit composition, and (a2) heating the impregnated glass textile obtained in step (a1) to a temperature above the softening temperature of the glass frit; and (b) cooling the impregnated glass textile obtained in step (a) so as to obtain a glass sheet, and to a glass sheet manufactured using such a process.
Abstract:
The invention relates to a process for manufacturing flat glass, comprising, in succession: (a) immersing a glass textile into a molten glass bath so as to obtain a glass textile impregnated with molten glass, the glass forming the fibers of the glass textile having a softening temperature above that of the molten glass bath, (b) removing the impregnated textile from the molten glass bath, and (c) cooling the impregnated glass textile removed from the molten glass bath so as to obtain a glass sheet, and to a glass sheet manufactured using such a process.
Abstract:
A mat/mesh laminate for flexible floor covering slabs is formed by a glass fiber mat, bonded by a first organic polymer, having an air permeability, measured in accordance with standard NF EN ISO 9237 at a pressure of 200 Pa, of between 6000 and 12,000 l/m2·s, and by a glass yarn mesh having a titer of between 30 and 150 tex that is coated with a second organic polymer.
Abstract:
The invention is drawn to a method of coating a glass fiber textile comprising the following steps: —Preparing an aqueous coating composition comprising (a) 5 to 95% by weight, with respect to the total weight of (a) and (b), of a synthetic polymer or oligomer dissolved or dispersed in the aqueous coating composition, and (b) 5 to 95% by weight, with respect to the total weight of (a) and (b), of a dextrin exhibiting a weight-average molecular weight ranging from 250 000 to 2 000 000 Da and a solubility, measured according to a test A, ranging from 50 to 85%, —Applying said aqueous coating composition to a glass fiber textile, thereby obtaining a wet-coated glass fiber textile, —Submitting the wet-coated glass fiber textile to a step of drying and/or curing thereby obtaining a glass fiber textile coated with a water-insoluble polymer coating.
Abstract:
The invention relates to an aqueous binder composition containing, relative to the total dry weight of the binder composition, 10 to 40% by weight of a hydrogenated sugar, 25 to 55% by weight of citric acid, 25 to 50% by weight of a polysaccharide, and 1 to 10%, preferably 2 to 6%, by weight, of sodium hypophosphite or hypophosphorous acid. The polysaccharide is dissolved in the aqueous binder composition and chosen from functionalized starches and dextrins having a weight-average molar mass of between 150,000 and 2,000,000 and a solubility in water of between 50 and 85%. The invention also relates to a method for manufacturing non-woven webs based on mineral or organic fibers using such a composition and the non-woven webs thus obtained.
Abstract:
A carrier material for vinyl floor covering, wherein the carrier material includes a nonwoven layer containing at least 50 wt. % of thermoplastic fibers and a scrim for eliminating wrinkles in the vinyl floor covering. The scrim includes weft yarns having a linear density of 28 tex or less. The carrier material prevents the formation of surface irregularities and printing errors in the vinyl floor covering.
Abstract:
A fiber mat includes a unitary assembly of fibers including at least a first set of fibers and at least a first binder comprising an organic resin, wherein the unitary assembly of fibers includes a minority portion and a majority portion different than the minority portion, wherein the fiber mat provides at least a 5% increase in tear when placed in a bituminous roofing product compared to an equivalent bituminous roofing product made with a fiber mat of equivalent weight containing a homogenous mat structure.
