  • Materials that provide bioresistance and/or defoaming and slower cooling properties for aqueous quenchants
    Patent number: 10526447
    Abstract: Methods and compositions are provided for heat treating, e.g. quenching a metal. The quenching composition includes a composition that comprises a polyamidopolyamine compound having a molecular weight of about 500 to about 100,000 and comprising a pendent amino group; and/or a non-polymeric amidoamine having a molecular weight of about 290 to about 5000 and comprising an amino group; and a hydroxyl containing diluent. These compositions impart one or more of the functions of quenching, lubricity, anti/low foaming and/or bioresistance to the quenching fluid.
    Type: Grant

  • Compositions and Methods of Using Polyamidopolyamines and Non-Polymeric Amidoamines
    Publication number: 20180134846
    Abstract: Compositions comprising a polyamidopolyamine and/or a non-poly-meric amidoamine are disclosed for imparting multiple desired characteristics to a variety of industrial compositions. In certain embodiments, these compositions are prepared by condensing a C4 to C16 poly basic acid, monobasic acid or derivative thereof with a polyamine comprising a primary amino group, and in the presence of an optional organic diluent. Certain specific polyamidopolyamine and a non-polymeric amidoamine formulae and compositions containing same are disclosed, as are methods of use of these compositions.
