PGMEA 99.5% Semiconductor Solvent

PGMEA 99.5% Semiconductor Solvent (CAS 108-65-6, molecular formula C6H12O3) is a process chemical for electronics and metal finishing, where trace metal content and particle contamination matter as much as headline assay. China Chemicals supplies it at 99.5% min in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as PGMEA, Propylene Glycol Monomethyl Ether Acetate, PMA. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Photoresist casting solvent in lithography
Edge bead removal and resist thinning
High-solids coating and ink formulation
Cleaning solvent for coating equipment
Slow-evaporating retarder in automotive refinish
