Usage
1). Sodium formate used as Leather tanning agent, catalyzer, disinfector in leather industry, serves as camouflage salt in the chrome tanning method.
2). Sodium formate used in catalyst and stabilizer compositions, and in the printing and dyeing of textiles as a reducing agent.
3). Sodium formate used as the raw material in the manufacturers of sodium hydrosulphite, formic acid and oxalic acid.
4). Sodium formate used in completion fluid in oil field, drilling fluids.
5). Sodium formate used as anti-frosting agent in concrete.
Storage
Sodium formate should be prevent exposure to moisture in the storage and transportation. If lumping occurs, the properties of the product will not change and it can be used normally after being pulverized.
