Description

3-Methoxybutanol (CAS 2517-43-3 ) is a glycol ether-type solvent used across industrial cleaning, coating, and personal care formulations. Its slow evaporation profile and miscibility with both water and organic solvents make it a practical choice. Formulators utilize this chemical for managing solvent balance and substrate compatibility. In metalworking and industrial cleaning, it functions as a co-solvent in degreasing compounds and aqueous cleaning concentrates where controlled evaporation is required. Printing and packaging formulators incorporate it into ink systems to improve flow, open time, and adhesion on difficult substrates. This versatility allows for high-performance results in demanding industrial environments. In personal care, it acts as a carrier solvent in formulations such as hair care products and skin cleansers. It is often preferred over more aggressive alternatives when a mild, slow-evaporating solvent is necessary for the application. Coating manufacturers also use it to optimize viscosity and film formation in waterborne and solvent-borne systems. This ensures a consistent finish and reliable performance across various surface types and application methods. The product is supplied as a clear liquid, typically in drum and IBC quantities suited to industrial procurement volumes. It is available in technical grade for industrial and coating applications requiring high-volume supply. Purity specifications generally range from 98% upward to meet strict manufacturing requirements. Documentation packages including COA and SDS are available for regulatory and QA review to ensure compliance with safety standards. Contact us for supply of 3-methoxybutanol Request Quote
