Conversion Coating Agent for Immersion of Zinc Phosphate on Steel Surfaces for Various Operations for Cold Deformation of Metal (170°F to 185°F).
Bonderite® M-ZN 198X (previously known as Bonderite 198X) is a powerful chemical agent that produces a dark, zinc phosphate coating adhered to steel surfaces prior to cold deformation of metal (i.e. drawing). Bonderite® M-ZN 198X also imparts a dark, black appearance to the drawn metal surface.
Acid Ratio: 5 to 9
Accelerator: 1 to 7.5 points (Ideal 1.5 to 3 points)
Temperature: 170° to 185°F
Incomplete Surface Coverage & Poor Adhesion
Difficult to Apply Phosphate Process
Poor Friction Reduction
Bonderite® M-ZN 198X can be used in a variety of ratios dependent on application, some recommended starting ratios are below:
Batch
(47 lbs./3.5 gallons) M-ZN 198x per 100 gallons
Immersion Time: 2-10 minutes
Strand
(94 to 188 lbs./7 to 14 gallons) M-ZN 198X per 100 gallons
Immersion Time: 5-30 seconds
Tubing
(47 to 58 lbs./3.5 to 4.3 gallons) M-ZN 198X per 100 gallons
Immersion Time: 2-10 minutes
Extrusion
(47 to 80 lbs./3.5 to 6.0 gallons) M-ZN 198X per 100 gallons
Immersion Time: 3-10 minutes
