Industrial Grade 90% Formic Acid CAS 64-18-6 for Leather Tanning & Rubber Coagulation

Applications
Leather Tanning Industry (Core Application)
Primary tanning and deliming agent for leather processing:
Adjusts pH of tanning bath to promote uniform penetration of chrome tanning agents
Improves leather softness, fullness and tensile strength
Used in dehairing, bating and pickling processes to enhance production efficiency
Prevents mold growth on wet blue leather during storage and transportation
Rubber & Latex Industry
Universal coagulant for natural rubber and synthetic latex production:
Promotes rapid and uniform coagulation of latex without affecting rubber quality
Reduces production cycle time and improves processing performance
Used as vulcanization accelerator and antioxidant in rubber manufacturing
Textile Printing & Dyeing Industry
Acidifier and dyeing auxiliary for textile processing:
Adjusts pH of dye bath for acid dyes and reactive dyes
Improves dye uptake and color fastness on wool, silk and nylon fabrics
Used in printing paste preparation and fabric finishing processes
Agriculture & Animal Feed
Preservative and acidifier for silage and animal feed:
Inhibits harmful bacteria growth and preserves feed nutritional value
Improves feed digestibility and animal growth rate
Reduces winter milk production decline in dairy cows
Pesticide & Pharmaceutical Intermediate
Key raw material for synthesizing various chemicals:
Produces insecticides, herbicides and fungicides such as formamidine and amitraz
Used in manufacturing antibiotics, analgesics and anti-inflammatory drugs
Serves as a reducing agent in organic synthesis reactions
Industrial Cleaning & Descaling
Effective descaling agent for removing mineral scale from boilers, heat exchangers and industrial equipment; also used in metal surface treatment and electroplating processes.

Packaging & Storage
Standard packaging: 25kg/250kg UN certified HDPE plastic drums; 1000kg IBC tanks and ISO tank containers available for bulk shipments. Store in a cool (≤25°C), dry, well-ventilated Class 8 corrosive chemical warehouse with explosion-proof lighting and ventilation systems. Keep containers tightly sealed to prevent leakage and vapor emission; isolate from strong oxidizing agents, strong bases, food/feed products and combustible materials. Prohibit open flames, sparks and smoking in storage area. Shelf life is 12 months under recommended storage conditions.

Safety Information
Classified as UN 1779, Class 8 (Corrosive Substances) with Subsidiary Risk 3 (Flammable Liquid), Packing Group II for international transportation. Highly corrosive to skin, eyes and mucous membranes; inhalation of vapor causes severe respiratory irritation and damage. Operators must wear chemical-resistant gloves, splash-proof goggles, protective clothing and respiratory protection during handling. In case of skin/eye contact, flush immediately with copious amounts of water for at least 15 minutes and seek medical attention. All transportation complies with IMDG/IATA/ADR regulations; complete MSDS with emergency response procedures is provided with each shipment.
