Applications
1. For Waterborne & Solvent-borne Coatings: 2-Butoxyethanol (EGMBE, CAS 111-76-2) acts as a coalescing solvent and viscosity modifier in waterborne paints, lacquers and industrial coatings, improving film formation, gloss, leveling and freeze-thaw stability while ensuring good solvency for resin systems.
2. For Industrial & Household Cleaners: As an efficient coupling solvent, 2-butoxyethanol enhances the cleaning power of degreasers, all-purpose cleaners and glass cleaners, helping dissolve grease, oil and stubborn soils in household, automotive and industrial applications.
3. For Printing Inks: 2-Butoxyethanol provides excellent solvency and controlled evaporation for solvent-based and UV flexo/gravure inks, improving pigment wetting, flow and printability in packaging and commercial printing.
4. For Textile Processing Auxiliaries: Used as a solvent and leveling aid in textile dyeing, printing and finishing auxiliaries, 2-butoxyethanol improves dye penetration, bath stability and fabric hand feel in wet processing.
5. For Metal & Resin Processing: 2-Butoxyethanol is used in metal cleaning formulations, cutting fluid additives and as a solvent for resin systems and chemical intermediates, offering broad solvency with good water compatibility.
6. Consistent Quality For Global Industry: Supplied as a high-purity colorless liquid with stable water content and consistent solvency, 2-butoxyethanol gives coating, cleaning, ink and textile manufacturers a dependable glycol ether solvent with flexible packaging and stable supply.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
