Description

Tripropylene Glycol Monoethyl Ether is a high-purity, versatile glycol ether solvent with excellent solvency properties. It is valued for its ability to dissolve a wide range of materials, including resins, oils, and dyes, while offering favorable evaporation rates and low toxicity profiles. This makes it an essential component for formulators and manufacturers in industries such as coatings, inks, industrial cleaning, and chemical synthesis, where performance and reliability are critical.

Application

• Coatings & Paints: Acts as an active solvent and coalescing aid in water-based and solvent-based formulations, improving film formation and flow.
• Industrial Cleaners & Degreasers: Used as a key solvent in heavy-duty cleaning products for its ability to dissolve greases, oils, and resins.
• Printing Inks: Serves as a solvent and viscosity modifier in flexographic and gravure inks, enhancing print quality and drying characteristics.
• Chemical Intermediates: Employed as a building block in the synthesis of specialty chemicals, plasticizers, and other derivatives.
• Adhesives & Sealants: Functions as a solvent and plasticizer to adjust viscosity, improve adhesion, and enhance application properties.
• Metal Working Fluids: Incorporated as a coupling agent and lubricity additive in coolants and drawing compounds.

Quality Control

Our Tripropylene Glycol Monoethyl Ether is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, water content, and color 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 away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption.
