To use: 
Mainly used as reducing agent of electroless plating, the plating of large equipment and small objects can't be, or to demand higher precision with complex shape, embossed or deep hole wall, or require a higher surface hardness and wear resistance, or non-metallic materials such as plastic, ceramic, glass, quartz surface metallization uniform density can be obtained, and the more excellent ni-p plating coating. Widely used in electronics, aviation, machinery, petroleum and other industries. It can also be used as interface activator, molecular weight regulator and heat stabilizer of synthetic resin. In recent years, it is widely used in the fields of phosphorous flame retardant and cement admixture, which plays a significant role in improving the drying rate of concrete and increasing the firmness.
