Methacryloxypropylmethyldimethoxysilane

Methacryloxypropylmethyldimethoxysilane (CAS 14513-34-9), also known commercially as 3-(dimethoxymethylsilyl)propyl methacrylate, is a bifunctional organosilane coupling agent that bridges organic polymer matrices with inorganic substrates.

It carries both a hydrolyzable silane group and a reactive methacrylate group, enabling simultaneous surface bonding and participation in radical polymerization networks for various industrial applications.

In coatings and adhesives, it improves adhesion to glass, metals, and mineral fillers by chemically anchoring the organic binder to the substrate surface. This reduces delamination risk in demanding service conditions.

Sealant and elastomer formulators use it as a crosslinker to build moisture-cure networks with controlled flexibility and durability. It is essential for maintaining structural integrity in harsh environments.

Electronics manufacturers apply it as a surface primer or additive in encapsulants and underfill resins where reliable interfacial adhesion to silicon or ceramic components is critical for performance.

In fiber-reinforced composites and filled polymer systems, it treats filler surfaces to improve dispersion and mechanical integration within the matrix. This leads to enhanced physical properties and stability.

Supplied as a clear liquid in standard packaging ranging from small laboratory quantities to bulk drums. Technical-grade material is the primary commercial form, with purity specifications typically at 97% or higher.

Specialty grades targeting electronics or optical applications may carry tighter purity and low-halide specifications. We ensure all shipments meet rigorous internal quality control and safety standards.
