Description

Ethylenediamine Tetrakis(Ethoxylate-Block-Propoxylate) Tetrol is a specialized, multi-arm polyether polyol based on an ethylenediamine core, modified with blocks of ethylene oxide and propylene oxide. This unique star-shaped structure provides exceptional performance as a versatile surfactant, dispersant, and rheology modifier in demanding formulations. It is a critical component for manufacturers in the polyurethane, coatings, and advanced material sectors seeking to enhance product stability, compatibility, and processing characteristics.

Application

• Polyurethane Foam Systems: Acts as a key crosslinker and cell opener in flexible slabstock and molded foams, improving foam softness and airflow.
• Coatings & Adhesives: Functions as a pigment dispersant and compatibilizer in water-based and solvent-based systems, enhancing color development and film properties.
• Textile & Leather Auxiliaries: Used as a leveling agent, softener, and antistatic agent in fiber processing and finishing.
• Agricultural Formulations: Serves as an effective emulsifier and stabilizer in pesticide and herbicide concentrates.
• Personal Care Products: Employed as a mild surfactant and viscosity modifier in shampoos, body washes, and other cosmetic preparations.
• Industrial Cleaners: Enhances the wetting and soil suspension properties of heavy-duty detergent formulations.

Quality Control

Our Ethylenediamine Tetrakis(Ethoxylate-Block-Propoxylate) Tetrol is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in hydroxyl value, viscosity, water content, and ethylene oxide/propylene oxide ratio. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to guarantee it meets your precise formulation requirements.

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/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
