Description

Propylene Glycol Butyl Ether (CAS NO 15821-83-7) is a high-performance, slow-evaporating glycol ether solvent prized for its excellent coalescing and coupling properties. This versatile chemical is a critical formulation component, effectively bridging water-based and solvent-based systems to enhance product stability and performance. It is an essential raw material for manufacturers in the coatings, cleaning, and chemical processing industries seeking reliable solvency and formulation flexibility.

Application

• Coatings & Inks: Acts as a coalescing agent and solvent in water-based architectural paints, industrial coatings, and printing inks to improve film formation, flow, and leveling.
• Industrial & Institutional Cleaners: Used as a coupling solvent in heavy-duty degreasers, hard surface cleaners, and floor finishes for effective soil removal and stability.
• Chemical Processing: Serves as a reaction medium or solvent in the synthesis of resins, polymers, and other specialty chemicals.
• Metal Working Fluids: Incorporated into formulations to aid in lubricity, corrosion inhibition, and the solubilization of additives.
• Agricultural Formulations: Utilized as a solvent and carrier in pesticides and herbicides to enhance active ingredient solubility and application efficacy.
• Adhesives & Sealants: Functions as a plasticizer and solvent to adjust viscosity, improve open time, and enhance adhesion properties.
