Oxalic Acid 99.6% (CAS 6153-56-6): Solving Industrial Rust Removal Challenges
Industrial rust removal processes often face critical hurdles: inconsistent acid strength leading to uneven cleaning, batch-to-batch purity variations causing unexpected metal surface reactions, and supply disruptions delaying production schedules. As a chemical supplier with over 10 years of serving industrial clients across 50+ countries, we’ve witnessed how substandard oxalic acid can compromise both product quality and operational efficiency.
A Stable and Reliable Derusting Solution
Our Industrial Grade Oxalic Acid 99.6% delivers consistent performance to address these challenges. With a production capacity of 5000 tons monthly and ISO9001-certified manufacturing processes, we ensure stable supply even for large-scale industrial needs. This high-purity oxalic acid, also known as ethanedioic acid, provides the controlled acidity required for effective rust removal while minimizing metal pitting, making it ideal for precision manufacturing and heavy industry applications.
Typical Industrial Applications
Industrial Ethanedioic Acid Powder finds extensive use in metal surface treatment as a derusting agent, where its dicarboxylic acid structure effectively chelates metal oxides without excessive base metal corrosion. Beyond rust removal, it serves as a reducing agent in chemical synthesis, a cleaning agent for stone surfaces, and a processing aid in leather manufacturing. Its solubility in water and ethanol allows for flexible formulation into various industrial cleaning solutions.
Why Key Specifications Matter
The 99.6% purity level of our oxalic acid is critical for industrial applications—lower purity can introduce impurities that interfere with metal treatment processes or leave residues on surfaces. The controlled melting point (101-102ºC) ensures consistent dissolution behavior in aqueous solutions, while the medium strong acidity balance provides effective rust removal without damaging sensitive alloys. Our strict quality control also guarantees low heavy metal content, meeting international export standards for industrial chemicals.
What You Gain With Our Product
Choosing our 99.6% Oxalic Acid for Derusting means reducing production downtime caused by supply shortages and minimizing material waste from inconsistent performance. Compared to lower-grade alternatives, our product delivers predictable results, reducing rework rates in metal treatment processes. Each batch comes with SGS-certified quality documentation, ensuring compliance with REACH and other global chemical regulations, while our established logistics network from Qingdao, Tianjin, and Shanghai ports guarantees timely delivery.
