摘要：
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.
