Zinc-Phosphate Coating Agent for Immersion Bath Systems for Steel Cold Forming Surface Preparation

Product Overview

BONDERITE® M-ZN 198X is a powerful chemical solution for zinc phosphate coating steel surfaces in cold deformation metalworking processes.  BONDERITE® M-ZN 198X is added to an immersion bath system that completely covers and forms a zinc phosphate conversion coating that imparts a dark black color and protects the rod or wire surface during cold forming processes.   


BONDERITE® M-ZN 198X is engineered for effective use in immersion bath systems at various dilution ratios depending on the type of metalworking process.  Recommended starting ratios are listed below based on operation type:
