    Zinc-Manganese phosphate coating agent


    1. Overview

    IC-2010-1 Zn-Mn series phosphate coating agent is used for surface phosphating of iron and steel parts, polished steel platefor automobiles. There are some advantages, such as low-temperature, fast filming, little sediment, light pollution. Phosphate coating is thin and firm, dense and uniform, and crystal nucleus is fine. The product is suitable for large-scale immersion line, spraying and the combination of spraying and dipping with strong processing capability. It is the representative product of high-quality products bonderite developed by our company.

    2. Using method

    Working liquid preparation (1 ton)

    1. Working liquid reagent

    IC-2010-1A Zn-Mn series phosphate coating agent

    IC-2010-1B Zn-Mn series phosphate coating agent

    NT-125 neutralizer

    AC-1301 accelerator

    b. First, add water to sink with 50 % of the capacity of sink. Second, 50 kg IC-2010-1A was added to the sink. Third, 6 – 6.50 kg NT-125 neutralizer was dissolved in a small amount of water, and then add slowly to sink and stir until flocculent precipitate was completely dissolved. Finally, add margin water, and stir evenly. Confirm process indicators. Before using heated to processing temperature, add AC-1301 accelerator of 1.5 kg, and stir evenly.
