1. Product Introduction & Main Application
Arnico’s Sodium Formate is a white, crystalline, hygroscopic organic salt, produced from the reaction of carbon monoxide with sodium hydroxide. This substance acts as an effective reducing agent and a source of formate ions, with diverse applications in leather tanning (as an acidifying and masking agent in the chrome process), as an airport runway de-icer, a cement-setting accelerator, and a raw material in the synthesis of formic acid and sodium hydrosulfite.

3. Features & Benefits
-
Mild Reducing & Buffering Agent: Possesses a mild reducing power and ideal pH for sensitive processes like leather tanning and papermaking.
-
Concrete-Setting Accelerator: An effective anti-freeze that reduces the setting time of cement in cold weather.
-
A Safe & Transportable CO Source: In-situ generation of carbon monoxide and formic acid upon the addition of a stronger acid.
-
Environmentally Friendlier than Salt: Use as an airport runway de-icer causes significantly less corrosion than sodium chloride.
4. Industrial Applications
-
Leather Industry: An acidifier and masking agent in chrome and vegetable tanning.
-
Construction & Civil Engineering: A fast-setting and anti-freeze additive for concrete.
-
Oil & Gas Industry: A shale stabilizer and lubricant in drilling fluids.
-
Chemical Industry: The production of formic acid and sodium dithionite (hydrosulfite).
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This material is a mild eye and skin irritant. On contact with strong acids, it releases CO gas (toxic). The Arnico MSDS file must be obtained.
-
Storage Conditions: Store in sealed, completely moisture-proof bags, in a dry, cool place, and away from acids and strong oxidizers. It is highly hygroscopic.
-
Personal Protective Equipment (PPE): When decanting, the use of a dust mask and safety goggles is required.
6. Quality Assurance & COA
Arnico Sodium Formate shipments are accompanied by a Certificate of Analysis (COA) detailing the purity percentage and pH value.
