Description

Triethylene Glycol Monoheptyl Ether is a high-purity, non-ionic surfactant and solvent belonging to the glycol ether family. This compound is valued for its excellent solvency power, controlled evaporation rate, and ability to act as a coupling agent in complex formulations. It is essential for manufacturers in the coatings, cleaning, and chemical processing industries seeking to enhance product performance and stability.

Application

• Industrial & Institutional Cleaners: Acts as a coupling agent and solvent in heavy-duty degreasers, hard surface cleaners, and floor care products.
• Coatings & Inks: Used as a coalescing aid and flow modifier in water-based paints, lacquers, and printing inks to improve film formation and application properties.
• Metalworking Fluids: Serves as a lubricity additive and coupling agent in synthetic and semi-synthetic coolants and drawing compounds.
• Chemical Intermediates: Employed as a raw material in the synthesis of specialized esters, plasticizers, and other functional chemicals.
• Textile Processing: Functions as a dye carrier and leveling agent in dye baths and fabric treatment formulations.
• Agricultural Formulations: Used as a solvent and penetrant in pesticide and herbicide concentrates to improve efficacy and stability.

Quality Control

Our Triethylene Glycol Monoheptyl Ether is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee traceability and compliance with your requirements.

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); keep containers tightly sealed when not in use to prevent absorption of atmospheric moisture. Keep away from strong alkalis and incompatible materials.
