Product Description

UCON® Ouenchant B is an aqueous solution of a liquid organic polymer and corrosion inhibitors. The organic polymer used in UCON Ouenchant B is inversely soluble in water. At ambient temperatures, the polymer is completely soluble in water and produces clear homogeneous solutions. At temperatures above 165°F (74°C); however, the polymer separates from water as an insoluble phase. When hot metal is quenched in a diluted solution of UCON Quenchant B, a film of the liquid organic polymer is deposited on the surface of the hot metal. The rate at which the metal is cooled is governed, in part, by the thickness of the polymer-rich film. The thickness of this film is controlled by the concentration of UCON Ouenchant B in the quench bath. The cooling rate is controlled also by adjusting the quench bath temperature and/or the rate of agitation. The main difference between UCON Ouenchant Band other UCON Quenchants is its higher molecular weight, which provides uniform heat transfer in the range of medium speed oils to slow oils.

Featured Benefits
  • Opportunity is presented for reduced costs of protection equipment and/or fire insurance
  • Produces slow 'C' phase cooling due to its higher molecular weight ingredient. The major make-up requirement is for water lost by evaporation
  • Eliminates the smoke, soot, and residues common to oil quenchants. Equipment maintenance and plant cleanliness are easier to achieve.
  • Fully soluble in water. Resistant to bacterial growth, exhibits low Biochemical Oxygen Demand (BOD), and is essentially non-toxic to bluegill sunfish
