  • PERDRAW 9947
    A heavy duty emulsifiable oil compound which can handle a wide variety of metal forming and metal removal operations without the use of chlorine. Perdraw 9947 is a unique product which offers new technology to the industry....

  • PERDRAW 9947

    Chlorine-Free Heavy Duty Metal Forming Compound

    Perdraw 9947 forms a tight stable emulsion when mixed at 19:1 (water : oil).  The compound is able to handle even the most difficult cutting operations on both ferrous and non-ferrous materials.  When mixed as an invert paste at (2 or 3:1) it forms a free flowing paste which can handle difficult drawing applications even on stainless steel.  Perdraw 9947 is easily rinsed from the parts and provides excellent cooling for the dies.  The formula has proven to be capable of reliably forming cup shaped parts out of both brass and aluminum on high speed progressive die machinery.  Perdraw 9947 can successfully replace heavily chlorinated water emulsifiable oil products.  Additional benefits of chlorine-free fluids include:

    • Minimizing rust and corrosion on parts
    • Eliminating the potential for of hydrogen embrittlement on aluminum parts
    • Lower cost to dispose of waste
    • Less smoke and mist created
    • Easier to clean from parts
