The coating obtained had the following properties: The corresponding auxiliaries and additives may be included in one or both of the components. Catalysts 3 promoting the addition of Si-attached hydrogen to aliphatic multiple bonds can be any desired catalysts which are known to promote this reaction.
Industrial fabrics usually need to be washed, dried and shrunk. Another object of the invention is a process for coating textile substrates, characterized in that aqueous emulsions of the invention are applied onto a fabric and cured in the emulsions on textile substrates and a step the coated textile is dried. Latest News of the Blog.
Particularly advantageously equipped with the inventive products polyamide or polyester fabrics can be used for manufacturing airbags for motor vehicles according to the inventive method.
The application of the coating material takes place during the washing process or immediately thereafter.
DE DEA1 en Process for coating substrates with aqueous emulsions containing organopolysiloxanes. Radicals with unsaturated aliphatic groups, such as vinyl, allyl, hexenyl or cyclohexenyl, may be present. Examples ddin substituted hydrocarbyl radicals are halogenated radicals, such as 3,3,3-trifluoropropyl, 3-chloropropyl or chlorophenyl.
An additional coating operation is no longer necessary. Audio and video engineering For manufacturing fin often coated fabrics may be used. Geeignete Emulgatoren sind vorzugsweise ionische und nichtionische Emulgatoren. The vulcanization of the silicone coating and the drying and shrinking of the textiles can be carried out in one operation.
Dies bedeutet eine signifikante Einsparung von Energie, Zeit und Kosten. Industrial fabrics usually have to be washed, dried and shrunk, to 35530 the high demands.
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. EP Coating compositions and air bags coated with them. Identical or different molecules of said organopolysiloxane 2 can be used. Aqueous emulsions comprising 1 an organopolysiloxane with SiC-attached vinyl groups in the terminal units, 2 an dni 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.
Physical testing – Sächsisches Textilforschungsinstitut e.V.
Bevorzugt wird ein Platingehalt von ppm, bezogen auf die eingesetzten Polysiloxane eingesetzt. Our offices will be closed from December 24, to January 2, inclusive. As examples of suitable organosilicon compounds as adhesion promoters 4 are preferably silanes with hydrolyzable radicals, and carbon-silicon bonded vinyl, acryloxy, methacryloxy, epoxy or xin anhydride groups.
The fabric obtained had the following dn. EP-A describes addition-crosslinking organopolysiloxane compositions without silicone resin in an organic solvent used for coating airbags.
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. An advantage of the 53503 process according to the invention that the cost of an additional coating step are saved.
The fabric obtained had the following properties: It is an object of the present invention to overcome the disadvantages of the above references and provide aqueous emulsions that have a low coating weight, improved adhesion of the coating, improved values in the ISO scrub test, and permits an inexpensive coating process.
In the present invention, the amounts of platinum 535300 used is generally between 3 and ppm, based on the siloxane content. Suitable emulsifiers are ionic and nonionic emulsifiers.
Bevorzugt wird ein Umsetzungsprodukt aus Vinyltriacetoxysilan und dem Silan der Formel a reaction product of vinyltriacetoxysilane and the silane of formula is preferably. ddin
Dieser Haftungsvermittler wird vorzugsweise in Mengen von 1 bis 20 Gew. We wish you a pleasant end-of-year holiday. The vulcanization of the silicone coating and drying and shrinkage of the textiles can be effected in a single operation. EP-A describes addition-crosslinking organopolysiloxane compositions without silicone resin in an organic solvent used for coating airbags, which organopolysiloxanes must have a specific molecular weight dinn.
