| Applications | Uses: Used to make organic coupling agents (adhesion promoters) in the plastics industry, [HSDB], Used to prepare a number of organic coupling agents utilized by the plastics industry as adhesion promotors., Used in the industrial production of trimethoxysilylpropyl methacrylate [2530-85-0] by direct addition of trimethoxy silane in the presence of radical scavengers., Used as an adhesive and bindings agent (92%), as an intermediate (7%) and as a surface active agent (1%)., Industry Uses: Adhesion, cohesion promoter, Intermediate, Methods of Manufacturing: Reaction of silicon with ethanol or methanol containing less than 2000 ppm water produces trimethoxy silane with cuprous chloride as the catalyst., Silane reacts with methanol at room temperature to produce ... trimethoxysilane., U.S. Production: 2023: 1, 000, 000 - <8, 500, 000 lb, 2022: 1, 2021: 1, 2020: 1, Silane, trimethoxy- is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and, or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B, 51FR21438)., Production volumes for non-confidential chemicals reported under the Inventory Update Rule. [Table#5871], Production volume for non-confidential chemicals reported under the 2006 Inventory Update Rule. Chemical: Silane, trimethoxy-. Aggreated National Production Volume: 1 to < 10 million lbs., 1702 tonnes in 2001, U.S. Imports: Trimethoxysilane is not imported into the United States, General Manufacturing Information: All Other Basic Inorganic Chemical Manufacturing, Paint and Coating Manufacturing, trimethoxy-: ACTIVE, Trimethoxysilane is not sold in industrial or other consumer markets and is not shipped from the original point of manufacture. Trimethoxysilane is produced and used in closed systems (hard piped) and is a site-limited intermediate., Trimethoxysilane is used in all cases (including those characterized as non-dispersive), as an intermediate in the production of organofunctional silanes. Similarly, in all cases (including those characterized as non-dispersive), the use concerns trimethoxysilane itself, not any hydrolysis or polymerization products. Note that the polymerization products are an artefact of testing in an aqueous or moisture containing environment, these are not produced during the use of trimethoxysilane. |
