Description

Butanoic Acid, Ethenyldimethylsilyl Ester is a specialized organosilicon compound that serves as a valuable building block in advanced material synthesis. Its unique structure, featuring both a silyl ether and a vinyl group, makes it a versatile reagent for introducing functional siloxane moieties into polymer backbones and surface coatings. This chemical is primarily sought by R&D and production teams in the silicone polymer, specialty adhesives, and surface modification industries for developing materials with tailored properties such as enhanced hydrophobicity, adhesion, and thermal stability.

Application

• Silicone Polymer Modification: Acts as a functional monomer or cross-linking agent in the synthesis of novel silicone resins and elastomers.
• Surface Functionalization Agent: Used to graft hydrophobic or reactive siloxane layers onto inorganic surfaces like glass, silica, or metals.
• Adhesive & Sealant Formulation: Imparts improved adhesion and flexibility as an additive in high-performance silicone-based adhesives and sealants.
• Release Coating Precursor: Serves as a key intermediate in the production of silicone release coatings for labels and packaging films.
• Hybrid Material Synthesis: Employed in sol-gel processes to create organic-inorganic hybrid materials with specific mechanical and surface properties.
• Pharmaceutical & Cosmetic Intermediates: Used in the research and development of siloxane-based carriers or delivery agents.

Quality Control

Our production of Butanoic Acid, Ethenyldimethylsilyl Ester adheres to stringent internal quality standards to ensure batch-to-batch consistency and purity for your critical applications. Each lot is analyzed via GC, NMR, and FT-IR to confirm identity and composition. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 2°C and 8°C (under refrigeration) to maximize shelf-life and stability. Keep away from heat, sparks, and open flame. The container must be kept tightly sealed in a dry environment to prevent moisture absorption and potential hydrolysis.
