EastaPure applications

Eastman EastaPure™ solvents, ketones and acids are useful in nearly every step of semiconductor manufacturing. EastaPure’s low metal content and higher purity result in a cleaner, smoother formulation and manufacturing process for electronics and technology professionals.

A gentle balance

The complexities of the manufacturing process demand solvents that are ultrapure to prevent impurities but still delicate enough to not damage any metallic components. Quality is efficiency, as leftover particles or clogged equipment can lead to defective chips or costly production line shutdowns. EastaPure products have a low metal and water count as well as limited nonvolatile residue, making them ideal for substrate preparation, adhesion promotion, cleaning and a range of other functions.
