Description

Butyl Lactate CAS NO 138-22-7 is a high-purity ester of lactic acid, valued for its excellent solvent properties, low volatility, and favorable environmental profile. This versatile chemical intermediate is crucial for formulators seeking effective, low-odor solutions with high solvency power for a wide range of resins and polymers. It is an essential component for manufacturers in the coatings, inks, and specialty chemical industries, where performance and regulatory compliance are paramount.

Application

• Coatings & Paints: Acts as a high-boiling, slow-evaporating solvent for acrylics, epoxies, and cellulose derivatives, improving flow and leveling.
• Printing Inks: Used as a coalescing agent and solvent in flexographic and gravure inks, enhancing gloss and adhesion.
• Industrial Cleaners & Degreasers: An effective component in solvent blends for removing oils, greases, and fluxes due to its strong solvency.
• Chemical Synthesis: Serves as a biodegradable intermediate and reaction solvent in the production of pharmaceuticals and agrochemicals.
• Adhesives & Sealants: Functions as a plasticizer and solvent to adjust viscosity and improve the open time of various adhesive formulations.
• Electronics: Employed in photoresist strippers and circuit board cleaners where a low-residue, efficient solvent is required.
