Es kann eine Art von Haftungsvermittler verwendet werden aber auch Gemische aus zwei oder mehreren Silanen oder deren Umsetzungsprodukte, bzw.
Fiber treatment compositions containing organofunctional siloxanes cin methods for the preparation thereof. In the aforementioned organopolysiloxanes may be identical interpolymers or mixtures of different copolymers each with the same degree of polymerization or different degree of polymerization.
Die Vulkanisation erfolgt zeitgleich mit dem Trocknungsvorgang.

Click for automatic bibliography generation. It can tissues from all weaves, nonwoven fabrics, knitted fabrics, scrims, knitted fabrics of all common yarns and fibers, natural fibers such as cotton, glass, wool, silk, synthetic fibers such as polyamides, polyesters, rayon, polyethylene, polypropylene, polyurethane, silk, rayon, cellulose coated become. The application of the products of the invention can be carried out in a conventional manner. A SumoBrain Solutions Company.
It can be used catalyst mixtures as well as only one type of the aforementioned catalysts. Rin textile substrates characterized in that textile substrates with emulsions according to one or more of claims 1 to 4 or produced are coated according to claim. Examples include sulfonic acid and its 535330, which can act as an emulsifier as well as sulfonates, such as sodium lauryl sulfonate, substituted with aliphatic hydrocarbon radicals benzenesulfonates such as sodium dodecylbenzenesulfonate, substituted with aliphatic hydrocarbon radicals naphthalenesulfonates, Polyethylenglycolsulfonat and lauryl, polyethylene oxide, polypropylene oxide, copolymers of ethylene and propylene oxide, Stearate and phosphates.
The carbon black is preferably carbon black, furnace black or lamp black. Sin emulsion-type silicone compositions. Process for coating textile substrates, characterized in that aqueous emulsions are applied to one or more of claims 1 to 4 or obtainable by the method of claim 5 onto a fabric and cured, the emulsions in a step on textile substrates and the coated fabric dried becomes.
There is no need for an additional coating process. Examples of organosilicon compound 4 useful as adhesion promoters are silanes with hydrolyzable radicals and vinyl, acryloyloxy, methacryloyloxy, epoxy or acid anhydride groups attached to silicon via carbon. A lick-roller is used to transfer this emulsion to a wet dtex polyamide fabric. The organosilicon compounds used in this invention are commercially available products or preparable by processes customary in silicone chemistry.
Domestic and commercial equipment.
Testing of organic materials; Separation test on fabric plies bonded together
Examples are sportswear, sports articles, such as sails, boat covers or materials for rucksacks and tents and protective clothing. Log In Sign Up. Dies trifft insbesondere bei der Verwendung zur Herstellung von Airbags zu.
Radicals having unsaturated aliphatic groups, such as preferably. Another object of the invention is a vulcanizate prepared by using an aqueous emulsion of the invention, which is heated. Industrial applications, such as tarpaulins, conveyor belts, compensators, foldable containers.
In the present invention, the amounts of platinum catalyst used is generally between 3 and ppm, based on the siloxane content. Also cyanoalkyl radicals, such as the cyanoethyl radical, may be included. Suitable emulsifiers are ionic and nonionic emulsifiers.
The corresponding auxiliaries and additives may be included in one or both of the components. This coating system is an aqueous silicone coating system which, after vulcanization, has exactly the right property profile for an airbag. Aircraft and space vehicle engineering Yarn-to-yarn friction, which leads dun reduction in the tensile strength and is created by vibrations, can be prevented by the present elastomer coating.
What is claimed is: Beschichtet wurde ein dtex Gewebe. EP describes a liquid silicone rubber that is completely solvent-free.

Process for coating substrates with aqueous emulsions containing organopolysiloxanes. Base fabric for air bag. Bevorzugt sind nichtionische Emulgatoren. Aqueous emulsions can be prepared using any desired adhesion promoters.
Examples of hydrocarbyl radicals R are alkyl radicals, such as methyl, ethyl, n-propyl, isopropyl, butyl, octyl, tetradecyl or octadecyl; cycloaliphatic hydrocarbyl radicals, such as cyclopentyl, cyclohexyl or methylcyclohexyl; aryl radicals, such as phenyl; alkaryl radicals, such as tolyl; aralkyl radicals, such as benzyl dinn phenylethyl. Industrial fabrics usually have to 53350 washed, dried and shrunk, to meet the high demands.
If the diorganopolysiloxanes contain different diorganopolysiloxane units, the distribution may be random or block.
The vulcanization is conducted simultaneously with the drying process. This is particularly the case of fabrics used for the production of airbags, desired and particularly advantageous. The invention relates to aqueous emulsions, to a process for their preparation, to compositions which can be prepared using these aqueous emulsions, to a process for coating organic fibers using such aqueous emulsions, and these emulsions coated textile substrates.
Mechanical systems and components for general use However, it can all be included those as described above as R. The primary particle size of the carbon blacks used may be between 10 and nm. Bevorzugt wird ein Umsetzungsprodukt aus Vinyltriacetoxysilan und dem Silan der Formel a reaction product of vinyltriacetoxysilane and the silane of formula is preferably verwendet.
Wovens coated according to the present invention provide technical advantages. The residence time required for the vulcanization depends on the coating weight, the thermal conductivity of the fabric and the heat transfer to the coated textile and may be between 0.
Examples of substituted hydrocarbyl radicals djn halogenated radicals, such as 3,3,3-trifluoropropyl, 3-chloropropyl or chlorophenyl. Rubber and plastic industries A1 Designated state s: Examples of such catalysts are preferably metallic, finely divided platinum platinumruthenium, rhodium, palladium or iridium.
