  • Environmental wipe solvent processes
    Patent number: 6248403
    Abstract: A non-chrome process for the pretreatment of substrate surfaces to simultaneously clean them and improve their bonding strength for organic coatings such as adhesives, protective primers, sealants, paints, composites and similar materials conventionally bonded to such substrates, including non-chromated or chromated curable organic resin protective coatings applied directly to bare aluminum substrates. The invention involves the use of novel wipe solvent compositions containing a major volume of an environmentally-safe volatile organic solvent which has a low composite vapor pressure or is otherwise exempt from federal, state or local regulations, and a minor volume of a polyfunctional coupling agent, preferably of the silane type.
    Type: Grant
    Filed: January 3, 2000
    Date of Patent: June 19, 2001
    Assignee: Northrop Grumman Corporation
    Inventors: John Douglas Weir, Joanne Swiderski McLaughlin
