Notes
1. Due to the wide quality range of ferro phosphorus powder in the market, you need to choose products produced by legitimate companies to avoid poor purity and content affecting the performance.
2. If Si, S, Mn, C in ferro phosphorus powder are a little higher, the electrical conductivity and electrochemical capacity of zinc dust paint will be affected. So please notice the ferro phosphorus powder supplementation in formulation design of zinc dust paint according to the test result.
3. Surface treatment of substrate is a key factor that determines the performance of the coating adhesion. In order to ensure the full contact of zinc powder and ferro phosphorus powder to make conductive electricity effect and antirust effect work well, the substrate surface have to be clean without water, oil or any other pollutant, especially oil and greas.
