Abstract
There is provided a nonaqueous powdered metal paste composition and a vehicle therefor, characterized by resistance to slumping upon heating to the fusion point of the metal, fusion point being above 500.degree. C., including the powdered metal, and an organic material having a surface tension of from 43 to 65 or higher dynes/cm. at 20.degree. C.
Claims18
A nonaqueous powdered metal paste characterized by resistance to slumping during heating to the fusion point of the metal moiety of the paste comprising from 60 to 90 parts by weight of a powdered metal, powdered metal alloy or a blend of powdered metals having a melting point above 500.degree. C. and having a particle size less than 20 mesh (U.S. Standard Sieve Size) and from 0 to 39 parts by weight of a natural or synthetic hydrocarbon having a melting point above 15.degree. C. and below the fusion point of the metal or metal alloy powder, and from 0.5 to 40 parts by weight of a nonaqueous organic liquid compound having a surface tension of from 43 to 65 or higher dynes/cm. at 20.degree. C.
