As a widely applied basic organic chemical raw material, industrial oxalic acid dihydrate features stable physical and chemical properties, excellent chelating and reducing capacity. It continuously serves two core global sectors: metal surface treatment and textile printing & dyeing, and has become an essential chemical for long-term procurement by numerous manufacturers.
The industrial oxalic acid dihydrate we supply maintains a minimum purity of 99.6%, complying strictly with GB/T 1626-2008 standard for industrial oxalic acid. Impurity parameters are well controlled. The crystals are uniform with good water solubility and tiny batch-to-batch deviation, suitable for large-scale continuous industrial production. Standard packing is 25kg woven bags with inner plastic liners. Bulk cargo and container shipment are available. We can provide complete COA and MSDS documents to meet chemical import customs clearance requirements worldwide.
In metal treatment, industrial oxalic acid dihydrate efficiently dissolves rust, oxide scale and mineral deposits on steel and hardware workpieces via powerful chelating performance. Compared with traditional inorganic strong acids, it brings lower risk of over-corrosion on substrates. It is widely adopted for pre-plating activation, hardware rust removal & polishing, pipeline and equipment descaling, improving adhesion of coatings and electroplating layers and reducing reject rates during metal processing.
Textile printing and dyeing stands as another major application. Acting as an eco-friendly bleaching auxiliary and dye bath regulator, industrial oxalic acid removes natural pigments and rust stains on cotton, linen and chemical fabrics to enhance base fabric whiteness. Moreover, it chelates metal ions in water to prevent bleaching system failure, improve dyeing uniformity and color fastness, covering grey fabric pretreatment, textile restoration and garment rinsing.
Beyond the two key sectors, the product is also applicable in rare earth separation, leather processing and building material cleaning. With the recovery of global textile industry and growing foreign trade orders for metal processing, market demand for high-quality and steadily supplied industrial oxalic acid keeps rising. Supported by mature supply chains, we guarantee stable delivery for domestic and overseas clients and offer technical consultation to optimize formulas and operating processes according to regional production conditions.
Consistent quality of chemical materials directly determines finished product stability. We implement strict quality inspection throughout production, crystallization and screening to avoid specification fluctuation, helping overseas buyers prevent production line breakdown caused by inconsistent chemical raw materials. For global partners, sample testing, small trial orders and long-term framework supply are all accessible. We keep delivering cost-effective industrial oxalic acid dihydrate solutions for enterprises engaged in metal processing and textile bleaching.
