Nickel Institute > Additions to Sulphamate Nickel Solutions
By Dr. S. Alec Watson, Dec 1990. Additions to sulphamate nickel solutions are of two types: organic and metallic. The organic additives used are stress reducers, hardening agents, levelling agents and wetting agents just as in the Watts solutions. The metallic additions are usually cobalt or manganese. There are circumstances where both are used.
