Abstract: Corrosion of metal surfaces, particularly aluminium or aluminium alloy surfaces, is inhibited by contacting the metal surfaces with a solution comprising a mercapto-substituted silane and then preferably baking the metal to cure the silane coating. Multifunctional organo-mercapto-substitututed silanes are preferred in the practice of the process. Preferably, the treatment solution is an aqueous mixture of the mercapto-substituted silane and selected solvents.

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.
