Description

Acryloxytrimethylsilane is a versatile organosilicon monomer featuring both acrylate and silane functionalities in a single molecule. This dual reactivity makes it a critical building block for synthesizing advanced polymeric materials with enhanced surface adhesion, crosslinking density, and weather resistance. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to improve product performance. The compound is supplied with the CAS registry number 13688-55-6.

Application

• Crosslinking Agent in UV-curable coatings, inks, and adhesives to enhance hardness and chemical resistance.
• Surface Modifier for inorganic fillers (e.g., silica, glass) to improve compatibility and dispersion in polymer matrices.
• Adhesion Promoter in primers and sealants for substrates like metals, glass, and plastics.
• Silicone Resin Intermediate for producing high-performance resins with tailored properties for release coatings and encapsulants.
• Monomer for Hybrid Polymers (e.g., acrylate-silicone copolymers) used in weatherable exterior coatings and optical materials.
• Fiber Treatment to impart water repellency and increased durability to textiles and glass fibers.

Quality Control

Our Acryloxytrimethylsilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets the high standards required for industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) at temperatures between 2°C and 8°C to maximize shelf life and maintain product integrity. Keep away from strong oxidizing agents.
