Polishing and electroless nickel compositions, kits, and methods |
摘要 |
Disclosed are various methods, kits, and compositions in the field of electroless nickel plating and chemical polishing. An electroless nickel plating composition may include a surfactant-brightener; a coupler; a bismuth metallic stabilizer; and organosulfur stabilizer and a bismuth complexer. Prior to plating, a substrate may be polished with a polishing composition that includes a surface blocker and a surface leveler. When practiced in accordance with the preferred teachings described herein, the electroless nickel plating composition is capable of providing a mirror-bright, lustrous finish, and has good leveling properties. The composition may be made without lead or cadmium. |

1. A kit comprising:
a first container containing a first composition and a second container containing a second composition, said first composition containing nickel and said second composition containing a reducing agent, said first and second compositions being combinable to form an electroless nickel plating composition; said first composition containing a surfactant-brightener, said surfactant-brightener being present in an amount effective to enhance luster of an object plated with said electroless nickel plating composition, and a coupler, said coupler being present in an amount effective to inhibit oil-out of said surfactant-brightener; said second composition containing a bismuth metallic stabilizer in an amount effective to inhibit plate-out of said electroless nickel plating composition, and a bismuth complexer, said bismuth complexer being present in an amount effective to inhibit precipitation of bismuth. |
