2-Butoxyethanol, widely known by its trade name Butyl Cellosolve, is a versatile organic solvent with the chemical formula C6H14O2 and CAS number 111-76-2. As a glycol ether, it features a unique molecular structure containing both ether and alcohol functional groups, granting it amphiphilic properties. This clear, colorless liquid is characterized by a mild, ether-like odor and is completely miscible with water and a broad range of organic solvents. Produced commercially by the reaction of ethylene oxide with n-butanol, it is highly valued for its high boiling point, low volatility, and excellent solvency for resins, oils, and waxes. Its ability to act as a coupling agent makes it indispensable in the formulation of water-reducible coatings and industrial cleaning agents. By stabilizing heterogeneous mixtures and improving flow characteristics, 2-Butoxyethanol ensures high performance in demanding industrial applications while meeting technical specifications for chemical stability and compatibility.
* Superior Coupling Ability: Bridges the solubility gap between water and organic solvents, creating stable emulsions. * Enhanced Film Formation: Functions as an effective coalescing agent, improving the durability and finish of latex paints. * High Solvency Power: Dissolves a wide variety of resins, including alkyds, epoxies, and nitrocellulose. * Controlled Evaporation: Features a low evaporation rate that enhances flow and leveling in surface coatings. * Surface Tension Reduction: Lowers the surface tension of liquids, facilitating superior wetting and penetration of substrates. * High Flash Point: Offers a safer profile compared to lower molecular weight alcohols and ethers.
