Description

Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Ethoxylated is a specialized organosilicon polymer featuring a polydimethylsiloxane (PDMS) backbone terminated with hydroxy groups and modified with ethoxylated side chains. This unique hybrid structure combines the excellent release, lubricity, and thermal stability of silicones with enhanced hydrophilicity and compatibility with polar systems offered by the ethoxylate groups. It is a critical performance additive for formulators seeking to modify surface properties, improve wetting, or act as a reactive intermediate in coatings, personal care, and polyurethane systems.

Application

• Polyurethane Foam Modifier: Acts as a cell opener and stabilizer in flexible polyurethane foam production, improving airflow and foam physical properties.
• Coating & Ink Additive: Enhances substrate wetting, flow, and leveling in water-based and solvent-based coatings, inks, and adhesives, reducing surface defects.
• Personal Care & Cosmetics: Used as an emollient, conditioning agent, and gloss enhancer in hair care products, skin creams, and color cosmetics, providing a soft, non-greasy feel.
• Textile & Fiber Treatment: Imparts softness, lubricity, and anti-static properties to synthetic and natural fibers during processing and finishing.
• Release Agent Intermediate: Serves as a key reactive component in the synthesis of cured silicone release coatings for labels, tapes, and industrial molding.
• Surfactant & Defoamer Component: Utilized as a building block for creating specialty silicone-polyether surfactants and high-performance defoamers.

Quality Control

Our Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Ethoxylated is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as viscosity, hydroxyl value, ethylene oxide content, and silicon content. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and potential oxidation. Keep away from strong oxidizing agents.
