Full Description

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 (MPTMS) used for?

MPTMS 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 MPTMS, 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 MPTMS?

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 MPTMS?

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 MPTMS packaged and priced?

RawSource ships MPTMS 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.
