Application :
1. mainly used for electroless nickel plating. It acts as a reducing agent in the nickel plating solution, can combine with the nickel to form the chelate and control the acidity and alkalinity, and can effectively improve the surface property and the smoothness of the nickel plating product.
2. widely used in electronics, aviation, machinery, petroleum and other industries.
3. can be used as synthetic resin interface activator, molecular weight regulator, heat stabilizer and food additives.
