Ethylene Glycol Mono-2-Ethylhexyl Ether (2-EHG), identified by CAS No. 1559-35-9, is a high-boiling, slow-evaporating glycol ether that serves as a versatile solvent and coalescing agent in industr…
Low Volatility: Extremely low evaporation rate ensures long-lasting performance and contributes to low-VOC compliance.
Excellent Coalescing Power: Facilitates high-quality film formation in waterborne and solvent-borne coatings by lowering the Minimum Film Forming Temperature (MFFT).
Surface Tension Reduction: Acts as a powerful surfactant-like solvent, improving substrate wetting and leveling.
High Solvency: Exhibits strong coupling ability for oils, fats, and resins, making it effective for heavy-duty cleaning.
Hydrophobic Character: Offers better water resistance in cured films compared to shorter-chain ethylene glycol ethers.
Safety Profile: High flash point minimizes fire hazards during storage and processing.
