Conversion coating agent that applies a zinc phosphate coating on steel surfaces before drawing operations.
Zinc phosphate coating on steel alloys during cold forming processes, such as:
Steel extrusion
Steel wire drawing
Steel rod drawing
Reduces metal-to-metal contact
Extends tool life
Allows faster drawing speeds
Reduces press downtime
Prevents part breakage
Provides smoother, higher quality surface finish
Poor drawing or cold forming performance
Corrosion or breakage on wire or rod
Poor lubricant retention during drawing operation
Poor surface finish on formed steel parts
