Oxalic Acid Dihydrate 99.6%: Solving Stone Cleaning Industry’s Purity and Consistency Challenges
In stone cleaning operations, inconsistent acid concentration often leads to uneven surface treatment, while impurity-laden chemicals can cause irreversible discoloration of natural stone. During our 10+ years of serving industrial clients, we’ve witnessed how delayed shipments due to unstable supply chains disrupt production schedules—especially critical for large-scale construction projects relying on timely stone maintenance.
Reliable Oxalic Acid Supply for Industrial Stone Cleaning
Our Oxalic Acid Dihydrate 99.6% addresses these challenges with industry-leading purity and batch consistency. As a chemical export platform with self-operated import-export rights, we ensure stable monthly production capacity of 5000 tons, supporting uninterrupted supply for industrial cleaning enterprises and mining operations across 50+ countries.
Key Industrial Applications
Beyond effective stone cleaning solutions, this industrial grade oxalic acid serves as a critical reducing agent in leather processing, aiding in deliming and bleaching stages. Its chelating properties make it invaluable in mining operations for mineral processing, while its medium-strong acidity enables controlled surface treatment in construction material manufacturing.
Why 99.6% Purity Matters in Stone Cleaning
The 99.6% purity level of our Oxalic Acid Dihydrate minimizes unwanted side reactions during stone cleaning, ensuring predictable etching rates on marble, granite, and limestone surfaces. Its defined melting point (101-102ºC) allows precise temperature control in industrial cleaning baths, while solubility in water and ethanol facilitates formulation of custom cleaning solutions. The low impurity profile directly reduces the risk of stone discoloration compared to lower-grade alternatives.
Quality Assurance: From Production to Delivery
Choosing our Industrial Grade Oxalic Acid means avoiding the hidden costs of substandard materials—rejected batches, rework expenses, and project delays. Our ISO9001-certified production process includes rigorous SGS testing, with each batch accompanied by a Certificate of Analysis (COA) verifying key parameters. This commitment to quality ensures compliance with international chemical standards, reducing customs clearance complications for cross-border shipments.
Our Commitment to Reliability
We implement multi-stage quality control, including HPLC purity analysis and solubility testing, to maintain consistent product performance. Every delivery includes comprehensive MSDS documentation for safe handling. With 10+ years of foreign trade experience and long-term relationships with 6,000+ industrial customers, we stand behind our product with a full replacement guarantee for non-conforming shipments. Our dedicated technical support team provides guidance on optimal solution preparation for specific stone types.
Certificate of Analysis & Documentation
Each shipment includes a batch-specific COA with detailed purity testing results and compliance verification. MSDS documents provide comprehensive safety handling instructions. For quality control verification, customers can request specific batch test data by referencing their order number, and full analytical reports are available upon request for regulatory compliance purposes.
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 terms (FOB/CIF). We provide detailed product specifications and can arrange sample testing for qualification. Upon confirmation, we process orders through secure payment channels and coordinate shipment from major ports (Qingdao, Tianjin, Shanghai) with full customs documentation to ensure smooth delivery.
Frequently Asked Questions
