Abstract

A low viscosity silicone glycol surfactant together with glycerin is added to a polytetrafluoroethylene dispersion for use with an electroless nickel plating bath. The improved plating bath produces a stable PTFE dispersion that continues to work as the plating bath ages and that produces an electroless nickel deposit with greater than 20 percent by volume of PTFE in the deposit.
