Oxalic Acid Dihydrate (Industrial Grade): Circular Economy & Advanced Manufacturing Applications
Printed Circuit Board Micro-etching Agent
In electronics manufacturing, oxalic acid dihydrate enables precise copper layer thickness control in PCB micro-etching processes. It improves surface roughness and enhances adhesion for subsequent plating, increasing circuit board reliability.
Rare Earth Element Separation & Purification Aid
In rare earth metallurgy, oxalic acid dihydrate forms soluble complexes with specific rare earth ions, enabling efficient separation and purification to improve resource utilization and product purity.
Industrial Catalyst Regeneration Cleaner
In petrochemical processes, oxalic acid dihydrate effectively cleans carbon-deactivated catalysts, restoring surface active sites to extend service life and reduce production costs.
