Description

(Methacryloxymethyl)Bis(Trimethylsiloxy)Methylsilane is a specialized organosilicon monomer featuring both methacrylate and siloxane functional groups. This unique bifunctional structure makes it a critical cross-linking agent and reactive intermediate for synthesizing advanced silicone-based polymers. It is essential for manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance product durability, adhesion, and surface properties.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and cross-linker to improve scratch resistance, weatherability, and adhesion to various substrates.
• Silicone Pressure-Sensitive Adhesives (PSAs): Used as a modifier to enhance tack, peel strength, and thermal stability of silicone adhesive formulations.
• Release Coatings: A key component in the production of silicone release liners for labels and tapes, providing controlled release properties.
• Hybrid Organic-Inorganic Polymers (ORMOSILs): Serves as a precursor for creating materials with tailored mechanical, optical, and surface characteristics for advanced optics and electronics.
• Surface Modification & Coupling Agent: Improves the compatibility and bonding between inorganic fillers (e.g., silica) and organic polymer matrices in composite materials.
• Dental & Biomedical Materials: Employed in the formulation of light-curable dental composites and biomaterial coatings due to its biocompatibility and polymerizable nature.

Quality Control

Our production of (Methacryloxymethyl)Bis(Trimethylsiloxy)Methylsilane adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided to guarantee the material meets your specific application requirements and supports regulatory compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C/59-77°F). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
