Butyl Glycolate, also known by its chemical name butyl hydroxyacetate, is an ester solvent that possesses a unique set of properties making it highly valuable in a variety of industrial applications. With the CAS number 7397-62-8 and molecular formula C6H12O3, this compound's chemical structure contributes to its effectiveness as a high-boiling solvent and a functional additive.

Physically, Butyl Glycolate presents as a colorless liquid. Its key characteristics include a relatively high boiling point of 183ºC at standard atmospheric pressure, and a flash point of 71.7ºC. These properties indicate that it is a stable compound with a low propensity for rapid evaporation, making it suitable for applications where controlled drying is desired. Its density is reported at 1.027 g/cm³, and its refractive index is 1.427. These parameters are important for formulators to understand when integrating Butyl Glycolate into their products to ensure compatibility and achieve desired physical attributes.

The chemical nature of Butyl Glycolate, being an ester derived from glycolic acid and butanol, imparts it with excellent solvency power. This allows it to dissolve and interact effectively with a wide range of resins and polymers. This solvency is the foundation for its primary applications as a paint additive, where it improves the flow and leveling characteristics of coatings. It is particularly beneficial in nitrocellulose lacquers, where it enhances both the smoothness of the finish and the gloss of metallic lacquers, contributing to a superior aesthetic outcome.

Another critical function of Butyl Glycolate is its role in defect prevention within paint films. It acts as a potent blush preventive in paints, safeguarding against the cloudiness that can occur when moisture interacts with the drying film, especially in cellulose acetate-based paints. Additionally, it serves as a wrinkle preventive for alkyd paints, ensuring that the applied film cures evenly without developing undesirable surface textures. These properties are vital for maintaining the quality and visual appeal of painted surfaces.

Furthermore, Butyl Glycolate finds use in the formulation of printing inks and emulsion polymers. In printing inks, its controlled evaporation rate ensures reliable performance during the printing process. In emulsion polymers, it can influence film formation and other important physical properties. The compound's stability and functional attributes make it a versatile ingredient for manufacturers seeking to optimize their product formulations and achieve superior performance standards.
