Description

Propylene Glycol n-Butyl Ether (CAS NO 10215-33-5) is a high-performance glycol ether solvent prized for its balanced evaporation rate and excellent solvency power for a wide range of resins and oils. This versatile chemical intermediate is essential for formulators seeking to optimize product performance, enhance flow characteristics, and ensure reliable batch-to-batch consistency. It is a critical component for manufacturers in the coatings, cleaning, and chemical processing industries.

Application

• Coatings & Inks: Acts as a coalescing agent and solvent in water-based and solvent-based paints, lacquers, and printing inks to improve film formation and flow.
• Industrial & Institutional Cleaners: Used as a key solvent in heavy-duty degreasers, hard surface cleaners, and metal cleaning formulations for its ability to dissolve oils and greases.
• Chemical Processing: Serves as a reaction medium or solvent in the synthesis of various specialty chemicals, agrochemicals, and pharmaceuticals.
• Adhesives & Sealants: Functions as a solvent and viscosity modifier to enhance the application properties and open time of adhesive and sealant products.
• Electronics Manufacturing: Employed in precision cleaning solutions for electronic components and circuit boards due to its effective solvency and favorable evaporation profile.
• Automotive & Aviation Fluids: Utilized in formulations for brake fluids, hydraulic fluids, and de-icing agents where specific solvency and low-temperature performance are required.
