Usage:

1. Mainly used as the reductant for chemical plating. A dense and uniform nickel phosphorus film can be obtained for both large equipment and tiny components. Articles with complicated external shape of convex concave lines or internal wall of deep-hollows, The surface of non-metals such as plastic, ceramics, glass etc. The film possess a good surface hardness and abrasion resistance.
2. Widely used in electronics, aviation, mechanism, and petroleum fields. Also used as interface activator..
