Description

12-[(Dimethylsilyl)Oxy]Octadecanoic Acid Methyl Ester is a specialized organosilicon-modified fatty acid ester, a key intermediate in advanced material synthesis. This compound is valued for its ability to impart unique surface-active and hydrophobic properties to polymers and coatings. It is primarily sought by R&D and production teams in the silicone, polymer additive, and specialty chemical industries for developing high-performance materials.

Application

• Silicone Polymer Modification: Acts as a reactive intermediate for introducing long alkyl chains into silicone backbones, enhancing flexibility and hydrophobicity.
• Surface Treatment Agent: Used to create hydrophobic and oleophobic coatings on textiles, paper, and various substrates.
• Lubricant & Release Agent Formulation: Serves as a key component in high-performance lubricants and mold release agents due to its low surface energy.
• Adhesive & Sealant Additive: Incorporated to modify rheology and improve the water resistance of adhesives and sealants.
• Cosmetic & Personal Care Ingredients: Utilized in the synthesis of silicone-based emollients and conditioning agents for hair and skin care products.
• Pharmaceutical Intermediates: Employed in the research and synthesis of prodrugs or drug delivery systems with tailored release profiles.
