Uses:

1, Mainly used as reductant of chemical plating. specialy for large-scale equipment and slender things that could not be electroplated.when some complex accidented veins request high precision or the things have deeply hole wall or the surface requests upper rigidity and have long life , when we need to plate the nickel and phosphor on the surface of plastic chinaware , glass , quartz and request the plating surface to keep compact and uniformity , we will choose it in the electroless plating.
2, It widely used in electron, aviation , machines, rock oil and other lines.
3, What is more , it can be used as Molecular weight regulator, heat stabilizer and food additive.
Packing: 25KG/ woven bag.
