Description

2,2,3,3,9,9,10,10-Octamethyl-4,8-Dioxa-3,9-Disilaundecan-6-Ol (Wxc04656) is a specialized organosilicon compound with a unique structure containing both siloxane and alcohol functional groups. This dual functionality makes it a valuable intermediate for synthesizing advanced silicone polymers and modifying material surfaces. It is particularly sought after by manufacturers in the silicone elastomer, resin, and specialty coatings industries who require precise control over cross-linking density and surface properties. Its role is critical in developing materials with tailored hydrophobicity, thermal stability, and mechanical performance.

Application

• Silicone Polymer Modification: Acts as a chain extender or cross-linking agent in the synthesis of high-performance silicone rubbers and resins.
• Surface Treatment Agent: Used to impart hydrophobic and oleophobic properties to glass, ceramics, and mineral surfaces.
• Adhesive & Sealant Formulations: Serves as a key ingredient in silicone-based adhesives and sealants to enhance adhesion and flexibility.
• Release Coatings: Employed in the production of non-stick release papers and films for industrial and packaging applications.
• Personal Care Products: Utilized as a conditioning agent and emollient in high-end hair care and skincare formulations.
• Pharmaceutical Intermediates: Functions as a building block in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems.
• Electronics Encapsulation: Used in potting compounds and encapsulants to protect sensitive electronic components from moisture and stress.

Quality Control

Our production of 2,2,3,3,9,9,10,10-Octamethyl-4,8-Dioxa-3,9-Disilaundecan-6-Ol adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and FTIR, to verify identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with each shipment, ensuring full traceability and compliance with your technical specifications and relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong acids and bases.
