Request SDS →3-Methacryloxypropyltrimethoxysilane (CAS 2530-85-0) is a methacrylate-functional silane coupling agent for unsaturated and acrylic polymer systems. It promotes resin-to-glass, resin-to-metal, and resin-to-resin bonds and is used to formulate adhesives with built-in primer systems and to make organosiloxane copolymers. The methacrylate group copolymerizes with the resin while the trimethoxysilyl group hydrolyzes to bond inorganic surfaces.

Frequently Asked Questions
What is 3-methacryloxypropyltrimethoxysilane used for?
3-methacryloxypropyltrimethoxysilane is a methacrylate-functional silane coupling agent for unsaturated and acrylic polymer systems. It promotes resin-to-glass, resin-to-metal, and resin-to-resin bonds, is used to formulate adhesives with built-in primer systems, and serves to make organosiloxane copolymers. The methacrylate group copolymerizes with the resin while the trimethoxysilyl group hydrolyzes to bond inorganic surfaces.
What is 3-(trimethoxysilyl)propyl methacrylate, and is it the same product?
Yes — 3-(trimethoxysilyl)propyl methacrylate is the same compound as 3-methacryloxypropyltrimethoxysilane, CAS 2530-85-0. It is also abbreviated TMSPMA or MPS. RawSource supplies it under these equivalent names.
What is the CAS number and formula of 3-methacryloxypropyltrimethoxysilane?
3-Methacryloxypropyltrimethoxysilane has CAS number 2530-85-0 and molecular formula C10H20O5Si, in the Silanes & Organosilanes family.
Where do I find handling and hazard data for 3-methacryloxypropyltrimethoxysilane?
Handling, GHS classification, and storage guidance are provided in the product Safety Data Sheet, which RawSource supplies with every order. Review the current SDS before use; store away from moisture and ignition sources per the SDS.
How is bulk 3-methacryloxypropyltrimethoxysilane packaged and priced?
RawSource ships 3-methacryloxypropyltrimethoxysilane in drums, totes, and IBCs with CoA and SDS per lot, and quotes per order since pricing tracks volume, packaging, and raw-material markets. Submit a bulk RFQ with your target quantity for a current quote and lead time.
What is the REACH and TSCA regulatory status of 3-Methacryloxypropyltrimethoxysilane?
3-Methacryloxypropyltrimethoxysilane (CAS 2530-85-0) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 219-785-8).
What is the CAS number of 3-Methacryloxypropyltrimethoxysilane?
The CAS number of 3-Methacryloxypropyltrimethoxysilane is 2530-85-0.
