Description

Sodium 2-Hydroxy-3-[3-[1,3,3,3-Tetramethyl-1-[(Trimethylsilyl)Oxy]Disiloxanyl]Propoxy]Propane-1-Sulphonate is a specialized organosilicon surfactant that combines the unique properties of silicone with the water solubility and surface activity of a sulfonate. This compound is engineered to deliver exceptional wetting, leveling, and foam control in demanding formulations. It is a critical performance additive for industries requiring advanced surface modification and compatibility with both aqueous and non-polar systems.

Application

• Polyurethane Foam Stabilizer: Acts as a key silicone surfactant for controlling cell structure and stability in flexible, rigid, and molded polyurethane foams.
• Coatings & Inks Additive: Provides superior substrate wetting, flow, and leveling in water-based and solvent-based coatings, paints, and printing inks.
• Personal Care Formulations: Used in hair care and skincare products as a conditioning agent and emulsifier, offering improved softness and combability.
• Textile & Fiber Processing: Enhances softness, lubricity, and anti-static properties in fabric finishing and fiber manufacturing.
• Adhesives & Sealants: Improves spreadability, adhesion, and compatibility in various adhesive and sealant systems.
• Agricultural Adjuvants: Functions as a surfactant to enhance the spreading and penetration of pesticides and herbicides on plant surfaces.
• Industrial Cleaners: Provides effective wetting and emulsification in hard surface cleaners and degreasers.

Quality Control

Our production of Sodium 2-Hydroxy-3-[3-[1,3,3,3-Tetramethyl-1-[(Trimethylsilyl)Oxy]Disiloxanyl]Propoxy]Propane-1-Sulphonate adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with industry specifications. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and ionic composition 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
