Description

4-Isopropoxybutanol is a versatile glycol ether solvent and chemical intermediate with a unique combination of properties. Its structure provides excellent solvency for a wide range of resins and polymers, coupled with favorable evaporation rates and low toxicity. This makes it a valuable component for formulators in the coatings, inks, and industrial cleaning sectors seeking performance and regulatory compliance.

Application

• Coatings & Paints: Acts as a coalescing agent and solvent in water-based and solvent-based architectural, industrial, and automotive coatings, improving film formation and flow.
• Inks & Printing: Used as a solvent and viscosity modifier in flexographic, gravure, and screen printing inks to control drying time and enhance print quality.
• Industrial Cleaners: An effective solvent in heavy-duty degreasers, metal cleaning formulations, and electronic circuit board cleaners.
• Chemical Synthesis: Serves as a key intermediate or building block in the production of specialty chemicals, plasticizers, and pharmaceuticals.
• Adhesives & Sealants: Functions as a solvent and processing aid to adjust viscosity and improve the application properties of various adhesive systems.
• Electronics: Employed in photoresist formulations and as a cleaning agent in semiconductor and electronics manufacturing processes.
