Product Description
Eastman EastaPure™ high purity PGMEA (propylene glycol monomethyl ether acetate) is a premium solvent engineered for demanding applications requiring exceptional purity. Through advanced filtration, it delivers an ultra-low particle count, ensuring superior performance and reliability. Real-time, inline analysis during filling guarantees that each batch meets the precise specifications you expect.
This colorless liquid features both ether and ester functional groups and is characterized by a mild odor and a slow evaporation rate, making it ideal for controlled processing conditions. Eastman EastaPure™ high purity PGMEA uses include photoresist applications, providing consistent solvency and coating uniformity. Additionally, it is well-suited for edge bead removal following spin coating, supporting high-quality surface finishes.
Choose Eastman EastaPure™ for a high-purity solvent that enhances process control and product consistency in advanced electronics manufacturing.
