IC－*****1Znic-Series phosphate coating agent

1. Overview

  IC******1 phosphate coating agent assigned two kinds including IC******1A for preparation and IC******1B for adding, which is little-sediment and low-temperature phosphating agent for surface phosphating of iron and steel parts, cold-rolled sheet. There are some advantages, such as low-temperature, fast filming, little sediment, light pollution. Phosphate coating is thin and firm, dense and uniform, and nuclei is small. The product is suitable for large-scale spraying line or 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

2.1 Tank liquor preparation (1 ton)

a. Tank reagent:  IC******1A zinc-series phosphate coating agent
