Description

Poly(Ethylene Glycol) Butyl Ether is a non-ionic surfactant and solvent belonging to the family of glycol ethers. This versatile chemical is valued for its excellent solvency power, low volatility, and ability to act as a coupling agent between water and organic phases. It is essential for formulators and manufacturers in industries such as coatings, inks, cleaning products, and agrochemicals, where precise control over solubility and surface activity is required.

Application

• Coatings & Inks: Acts as a coalescing agent and solvent in water-based paints, lacquers, and printing inks to improve film formation and flow properties.
• Industrial & Institutional Cleaners: Used as a coupling solvent and degreaser in heavy-duty cleaning formulations, including floor strippers and metal cleaners.
• Agrochemicals: Functions as a solvent and penetration aid in pesticide and herbicide formulations to enhance efficacy and stability.
• Chemical Intermediates: Serves as a raw material or reaction medium in the synthesis of other specialty chemicals, including plasticizers and lubricants.
• Textile Processing: Employed as a dyeing assistant and leveling agent to ensure uniform color application on fabrics.
• Personal Care & Cosmetics: Used in select formulations as a solvent and viscosity modifier for lotions and creams.

Quality Control

Our Poly(Ethylene Glycol) Butyl Ether is manufactured under a stringent quality management system. Each batch is tested against rigorous internal specifications to ensure consistency in critical parameters such as molecular weight distribution, hydroxyl value, and water content. A Certificate of Analysis (COA) detailing these results is provided with every shipment to guarantee product integrity and traceability for your quality assurance processes.

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 and heat sources. For long-term storage, consider using under an inert atmosphere to prevent moisture absorption and oxidation.
