Combat Rust Formation in Industrial Processes with High Purity Oxalic Acid CAS 144-62-7
Industrial manufacturers worldwide face critical challenges with rustproofing treatments—unstable chemical purity leading to inconsistent rust removal efficiency, batch-to-batch variations causing process disruptions, and unreliable suppliers failing to meet production deadlines. In our 10+ years serving metal processing and surface treatment industries, we’ve witnessed how substandard oxalic acid can compromise coating adhesion and accelerate equipment corrosion, resulting in costly rework and material waste.
A Stable Solution for Reliable Rustproofing Treatments
Our Industrial Grade Oxalic Acid delivers the consistency your operations demand. With a minimum purity of 99.6%, this high-purity white powder ensures uniform reaction performance in rust conversion processes, eliminating the variability that plagues lower-grade alternatives. Backed by a monthly production capacity of 6000 tons and strategic shipping ports in Qingdao, Tianjin, and Shanghai, we guarantee steady supply to support your manufacturing schedules—even for large-scale industrial requirements across 50+ countries.
Typical Industrial Applications
Ethanedioic Acid for Rustproofing serves as a critical component in metal surface treatment, where its chelating properties effectively dissolve iron oxides without damaging base metals. Beyond rustproofing treatments, this versatile compound finds applications in leather processing as a deliming agent, mining operations for mineral extraction, and stone cleaning for removing mineral deposits. Its role as a reducing agent also makes it valuable in chemical synthesis processes requiring controlled redox reactions.
Key Specifications That Impact Your Operations
The 99.6% purity level of our Oxalic Acid directly translates to reduced impurities that could interfere with rust conversion reactions, ensuring optimal performance in surface treatment baths. Its defined melting point (101-102ºC) and solubility characteristics allow for precise process temperature control, critical for maintaining consistent treatment quality. The medium-strong acidity profile strikes the ideal balance between effective rust removal and material safety, while the low heavy metal content meets international export standards for industrial chemicals.
Benefits of Our High Purity Oxalic Acid
Choosing our Industrial Grade Oxalic Acid minimizes production risks associated with inferior raw materials—such as uneven rust removal requiring reprocessing, coating failures due to surface contamination, and equipment damage from corrosive impurities. Compliant with ISO9001 quality standards and supported by SGS certification, our product ensures regulatory compliance for global shipments. The stable supply chain reduces inventory holding costs, while the 25kg packaging format optimizes handling efficiency in industrial facilities.
Our Quality Commitment
Every batch of our High Purity Oxalic Acid undergoes rigorous testing through HPLC and wet chemical analysis to verify purity and composition. We provide a Certificate of Analysis (COA) with each shipment, detailing batch-specific test results, and make MSDS documentation readily available for safety compliance. Our quality control system tracks raw material sourcing through production to delivery, ensuring traceability. In the rare event of non-conforming material, we offer unconditional replacement to minimize your operational disruption.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with comprehensive testing data, including purity, moisture content, and impurity levels. MSDS documents are provided in multiple languages to support global safety compliance. For critical applications requiring detailed verification, specific batch test records and chromatographic profiles can be requested through our technical support team.
Storage & Handling
- Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
- Keep away from incompatible materials, food and feed sources.
- Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
- Follow good industrial hygiene practices. Avoid inhalation and skin contact.
- Refer to MSDS for detailed storage and safety instructions.
Streamlined Order Process for Industrial Buyers
Initiate your purchase by submitting an inquiry with your required quantity and delivery timeline. Our technical team can provide sample evaluations for process validation before full-scale ordering. Once specifications are confirmed, we arrange production and shipping from our nearest port (Qingdao, Tianjin, or Shanghai) with full customs documentation. All industrial orders include standard export packaging and compliance certificates to facilitate smooth customs clearance.
