Ethoxylated propylene glycol monobutyl ether

　　Core Application Areas

　　Industrial Cleaning and Surface Treatment

　　Metal Degreaser: Ethoxylated propylene glycol monobutyl ether (n=5-8) can effectively dissolve mineral oils and greases, while enhancing aqueous phase dispersibility through the ethoxyl chain segments, used in automotive parts cleaning fluids, with an oil removal rate of over 98%. Electronic Cleaning Agent: High-purity products (n=10-12) can remove rosin flux residues from circuit board surfaces, with ion content < 10 ppm, complying with IPC-7510 standards.

　　Coatings and Inks

　　Waterborne Coalescing Agent: Products with n=8-10 can lower the Minimum Film Formation Temperature (MFT) of waterborne acrylic coatings to below 5℃, improving film flexibility and gloss, with a typical dosage of 3-5% of the formulation.

　　Ink Dispersant: Acts as a coupling agent in solvent-based inks, improving the dispersion stability of pigments (such as carbon black) in resins, preventing flocculation and settling.

　　Polymer Material Synthesis

　　Polyurethane Foam Stabilizer: Products with n=6-8 can regulate foam cell size distribution, enhancing the resilience and compression strength of polyurethane flexible foams, with a dosage of 0.5-1.0% of the polyol.

　　Polycarboxylate Superplasticizer Intermediate: Copolymerized with acrylic acid to produce high-performance superplasticizers; with a dosage of 1.0%, the water reduction rate can reach 35%, suitable for concrete in super high-rise buildings.

　　Agriculture and Daily Chemicals

　　Pesticide Emulsifier: Products with n=12-15 serve as O/W emulsifiers, capable of controlling the emulsion particle size of pesticide emulsifiable concentrates to below 2μm, with stability achieving no layering after 14 days of heat storage at 50℃.

　　Personal Care Solubilizer: Products with n=10-12 can solubilize essential oils (such as lavender oil) in aqueous systems, with a dosage of 1.5-2 times that of the essential oil, forming transparent and stable solutions.
