Description

Ethylenediamine Tetrakis(Propoxylate-Block-Ethoxylate) Tetrol is a specialized, multi-arm polyether polyol based on an ethylenediamine core, modified with blocks of propylene oxide and ethylene oxide. This unique star-shaped polymeric structure provides exceptional performance as a versatile surfactant, dispersant, and rheology modifier in demanding formulations. It is particularly valuable for industries requiring precise control over surface activity, emulsification, and viscosity, such as advanced coatings, polyurethane systems, and agrochemicals.

Application

• As a key surfactant and emulsifier in high-performance water-based coatings, inks, and adhesives.
• As a dispersing agent for pigments and fillers, enhancing color development and stability in complex formulations.
• As a rheology modifier and viscosity control agent in polyurethane foam systems and elastomers.
• As a stabilizer and compatibilizer in agrochemical formulations like pesticides and herbicides.
• As a intermediate for synthesizing more complex specialty polymers and surfactants.
• In the production of crosslinked polymers and resins where its tetra-functional nature is utilized.

Quality Control

Our Ethylenediamine Tetrakis(Propoxylate-Block-Ethoxylate) Tetrol is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in hydroxyl value, viscosity, water content, and molecular weight distribution. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. Under these conditions, the product is typically stable for 24 months from the date of manufacture. For long-term storage, consider using under an inert atmosphere to prevent moisture absorption and oxidation.
