  • Guanidine based vehicle/binders for use with oxides, metals and ceramics
    Patent number: 5256451
    Abstract: The use of guanidine salts of organic fatty acids (guanidine soaps) as vehicles and binders for coating substrate surfaces is disclosed. Being completely organic, the guanidine soaps can be burned off leaving no undesirable residue. Of special interest is the use of guanidine 2-ethyl hexanoate as the vehicle and binder for coating problematic surfaces such as in coating alumina fibers with platinum or zirconia. For this application the guanidine soap is used as a melt. For other applications the guanidine soap may be use in a solution with a variety of solvents, the solution containing chlorometalates or powdered metals, refractories or ceramics.
