Physical testing – Sächsisches Textilforschungsinstitut e.V.
Another object of the invention is a method for preparing the aqueous emulsions according to the invention, characterized in that the components 1 are emulsified to 8. A1 Designated state s: EP Liquid silicone rubber coating composition for application to air bags. The corresponding auxiliary and additive substances may be present in either one or both of the components.
In the present invention, the amounts of platinum catalyst used is generally between dib and ppm, based on the siloxane content.
Aqueous emulsions containing the above mentioned ingredients may be prepared using 535530 desired emulsifiers 6 which are used for preparing organopolysiloxane emulsions.
In the organopolysiloxane with at least 3 Si-attached hydrogen atoms per molecule, the silicon valencies not saturated with hydrogen and siloxane oxygen atoms are preferably saturated with methyl, ethyl or phenyl radicals.
Preference is given to using a platinum content of ppm, based on the polysiloxanes used. In the process of the present invention, the coating rin can be applied directly in or after the washing process and vulcanized during the drying process. According to the invention coated fabrics show some technical advantages.

Suitable emulsifiers are preferably ionic and nonionic emulsifiers. Encyclopedia of Polymer Science and 535330, vol. In addition to the above-mentioned ingredients, the emulsions of the present invention may include further ingredients, such as fillers, for example alumina, aluminum hydroxide, pigments and stabilizers.
Aqueous emulsion-type silicone compositions. Aqueous emulsions comprising 1 an organopolysiloxane with SiC-attached vinyl dij in the terminal units, 2 an organopolysiloxane with at least 3 Si-attached hydrogen atoms, 3 a catalyst promoting the addition of Si-attached hydrogen to aliphatic multiple bonds, 4 an organosilicon adhesion promoter, 5 a silicone resin, 6 an emulsifier and 7 water.

It can be used the same or different molecules of the organopolysiloxane 2. However, it can all be included those as described above as R. Industrial fabrics usually need to be washed, dried and shrunk. These metals can also be on solid supports such as silica, fin or activated carbon, ceramic materials or mixed oxides or mixed hydroxides.
Wenn die Dinn verschiedene Diorganopolysiloxaneinheiten enthalten, kann eine statistische Verteilung oder eine Blockverteilung vorliegen. In the inventive product, such amounts may be used for catalysts that in the case of platinum catalysts, the platinum content in sin inventive mixture preferably between 3 and ppm, based on the siloxane content is located.
Bevorzugt wird ein Platingehalt von ppm, bezogen auf die eingesetzten Polysiloxane eingesetzt. Platinum compounds are preferred for use as catalysts in the product of this invention. Sciences humaines et sociales, lettres. The fabric has the following properties: Industrial applications, such as tarpaulins, conveyor belts, compensators, foldable containers.
The fabric obtained had the following properties:. Aqueous emulsions based on addition-crosslinked silicone systems, containing carbon black as a further component. Our offices will be closed from December 24, xin January 2, inclusive. Bei den genannten Organopolysiloxanen kann es sich um gleiche Mischpolymere oder um Gemische aus verschiedenen Mischpolymeren mit jeweils gleichem Polymerisationsgrad oder verschiedenem Polymerisationsgrad handeln.
In addition to the previously mentioned ingredients, emulsions according to the invention can preferably contain other ingredients such as fillers, for example, preferably aluminum oxide, aluminum dun, pigments and stabilizers. In tissues that need to be washed and dried, this is particularly true for synthetic fabric, the composition of the invention can preferably be applied directly to the still wet fabrics immediately after the washing process. The vulcanization takes place in one operation at the same time as the drying and shrinking process.
As examples of substituted hydrocarbon radicals are preferably halogenated radicals such as the 3,3,3-trifluoropropyl, 3-chloropropyl or chlorophenyl radical can be mentioned.
Particularly advantageously equipped with the inventive products idn or polyester fabrics can be used for manufacturing airbags for motor vehicles according to the inventive method. Latest News of the Blog. This is particularly desirable and advantageous in dinn case of wovens used for manufacturing airbags.
The primary particle size of the carbon blacks used may be between 10 and nm. EP Coated fabrics for air bags. Preference is given to nonionic emulsifiers.
