• 99% Purity Premium Grade Tannic Acid – Ultra-Fine Powder for Precision Applications：High-quality lab-grade tannic acid with 99% purity ensures reproducible performance in even the most demanding formulations. The micronized, free-flowing powder offers exceptional solubility in water, alcohol, and acetone, enabling rapid dissolution, accurate measurement, and hassle-free mixing for both research environments and industrial production lines.
• Broad-Spectrum Utility Across Diverse Industries：This versatile chemical agent serves critical roles across multiple sectors: leather tanning and pelt processing, textile coloration (as a dye-fixing mordant), printing ink production, paper surface sizing for moisture resistance, metal corrosion inhibition, wastewater clarification through flocculation, and oilfield drilling fluid conditioning. A must-have stock item for manufacturing facilities, academic teaching labs, and advanced R&D centers.
• Superior Rust Conversion Capability for Metal Preservation：Acts as a chemical converter that transforms iron oxide (rust) into a durable, adherent ferro-gallate/tannate complex, forming a barrier that halts ongoing corrosion. This proven active component is widely specified in commercial rust converters and heritage metal conservation protocols. Particularly effective for hand tools, industrial machinery, ornamental ironwork, structural steel beams, and historic metal collectibles in workshop and museum conservation settings.
• Dual-Layer Protective Packaging System：Every unit is protected by a two-tier packaging solution: an outer aluminum foil barrier bag combined with an inner reclosable PP pouch. This dual-defense system effectively shields the contents from humidity, UV exposure, and particulate contamination. The reclosable inner pouch facilitates convenient product retrieval and safe re-storage, significantly extending usable product life.
