| abstract |
CATIONIC SURFACTANTS, E.G., QUATERNIZED DIMER TETRAMINE AND RELATED POLYMERIC FATTY POLYQUATERNARY AMMONIUM COMPOUNDS SUCH AS THOSE DERIVED FROM DIMER ACID AMINES, ARE ADDED TO AQUEOUS COOLANT FLUIDS OR CUTTING OILS TO ASSIST THE REMOVAL OF THE FINE SUSPENDED MATTER WHICH ACCUMU LATES DURING CUTTING OR GRINDING OF METALS, PLASTIC, GLASS, ETC. WITHOUT THE ADDITION OF THE CATIONIC SURFACTANT COMPOUND, A PORTION OF THE FINEST MATTER REMAINS SUSPENDED AND CANNOT BE REMOVED BY CONVENTIONAL METHODS SUCH AS FILTRATION. |
