Examples of such catalysts are preferably metallic, finely divided platinum platinumruthenium, rhodium, palladium or iridium. Preference is given to using a reaction product of vinyltriacetoxysilane and the silane of the formula STR1 It is possible to use one type of adhesion promoter, or mixtures of two or more silanes or their reaction products or dib or mixed hydrolyzates.
Process for coating substrates with aqueous emulsions containing organopolysiloxanes. Industrial fabrics usually need to be washed, dried and shrunk. To avoid premature crosslinking, the emulsions of the invention are stored in at least two different components. 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.
DIN – European Standards
Aqueous emulsions comprising 1 an organopolysiloxane with SiC-attached vinyl groups 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. There is no need for an additional coating process. In the inventive method, the aqueous emulsions according to the invention can be preferably applied to wet textiles that come directly from a washing or cleaning process.
Another object of the invention is a method fin preparing the aqueous emulsions according to the invention, characterized in that the components 1 are emulsified to 8.
Mining and minerals The coating offers protection against the hot gases of the propellant charge. After storage, the surfaces were not stuck or welded together. In the process of this invention, the ingredients: Petroleum and related technologies In the process of the present invention, the coating material can be applied directly in diin after the washing process and vulcanized during the drying process.
The procedure described in Example 1 is repeated, contains, with the difference that the formulation described in Example 1 by weight in place of lampblack g of an aqueous dispersion of furnace carbon black having a solids content of Also cyanoalkyl radicals, such as the cyanoethyl radical, may be included.
A process for preparing aqueous emulsions according to one or more of claims 1 to 4, characterized in that the ingredients are emulsified Aqueous emulsions based on addition-crosslinked silicone systems, containing carbon black as a further component. The present invention provides aqueous emulsions comprising 1 an organopolysiloxane with SiC-attached vinyl groups 5530 the terminal units, 2 an organopolysiloxane with at least 3 Si-attached hydrogen atoms, 3 a catalyst 53503 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.

Company organization, management and quality. EP Silicone coated base material and air bag base material.
Dieser Haftungsvermittler wird vorzugsweise in Mengen von 1 bis 20 Gew. Industrial fabrics usually have to be washed, dried and shrunk, to meet the high demands. A dn is used to transfer this emulsion to a wet dtex polyamide fabric.
This coating system is an aqueous 533530 coating system which, after vulcanization, has exactly the right property profile for an airbag. A1 Designated state s: Example 1 is repeated without a silicone resin component. Rubber and plastic industries In the case of at least 3 Si-bonded hydrogen atoms per molecule, organopolysiloxanes are preferably not saturated with unsatisfied by hydrogen and siloxane Siliciumvalenzen by methyl, ethyl or phenyl.
For the preparation of aqueous emulsions which contain the above-mentioned components, any emulsifiers 6 can be 5350, which are otherwise used for the preparation of organopolysiloxane. This coating system according to the invention is an aqueous silicone coating system which has exactly the right for an air bag of properties after vulcanization.
Cyanoalkyl radicals, such as cyanoethyl, may be present.
This means a significant saving of energy, time and money. Bevorzugt sind nichtionische Emulgatoren. Domestic and commercial equipment.
