Description

(3-Acryloxypropyl)Methyldichlorosilane is a highly reactive organosilicon monomer featuring both acrylate and dichlorosilane functional groups. This dual functionality makes it a critical intermediate for synthesizing specialized silicone-acrylate hybrid polymers and surface-modifying agents. It is essential for manufacturers in the advanced materials sector seeking to create products with tailored adhesion, release, or cross-linking properties. Key industries that utilize this compound include specialty adhesives & sealants, advanced coatings, and release liner production.

Application

• Synthesis of Silicone-Acrylate Hybrid Polymers: Acts as a key monomer for creating copolymers that combine the weatherability of silicones with the toughness and adhesion of acrylics.
• Surface Modification of Inorganic Fillers: Used as a coupling agent to treat silica, glass, or other minerals, improving their compatibility and dispersion in polymer matrices like acrylics and epoxies.
• UV-Curable Coating & Adhesive Formulations: The acrylate group enables participation in radical polymerization, making it valuable for formulating fast-curing, high-performance coatings and pressure-sensitive adhesives.
• Release Liner Manufacturing: Employed in the synthesis of silicone release agents where a tailored level of adhesion control is required for labels and tapes.
• Production of Specialty Silicone Fluids & Resins: Serves as a building block for creating modified silicones with specific functional endpoints for personal care or industrial applications.
• Adhesion Promoters: Enhances the bond between organic polymers and inorganic substrates like metals or glass in composite materials.

Quality Control

Our (3-Acryloxypropyl)Methyldichlorosilane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including Gas Chromatography (GC) for assay and impurity profiling. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from heat, sparks, and open flame.
