David Crotty has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polytetrafluoroethylene dispersion for electroless nickel plating applications
    Patent number: 6837923
    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.
    Type: Grant
    Filed: May 7, 2003
    Date of Patent: January 4, 2005

  • Process and composition for high speed plating of tin and tin alloys
    Patent number: 6562221
    Abstract: A composition and process for electroplating tin or tin alloys onto a substrate at relatively high current densities. The electrolyte comprises toluene sulfonic acid and a source of ammonium ions and/or magnesium ions. The process is particularly suited to high speed reel to reel or strip steel plating.

  • Composition and method for inhibiting corrosion of aluminum and aluminum alloys using mercapto substituted silanes
    Publication number: 20020172776
    Abstract: Corrosion of metal surfaces, particularly aluminum or aluminum 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-substituted 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.

  • High temperature continuous electrodialysis of electroless plating solutions
    Patent number: 6391177
    Abstract: An electrodialytic cell and process for its use in regenerating electroless plating solutions, particularly nickel-hypophosphite electroless plating solutions, are disclosed. The process is capable of operating at high temperatures and in a continuous fashion such that the plating operation is not interrupted and the steady state condition in the plating bath is achieved.
