ZX-317Medium Temperature Zinc-Manganese Series Phosphating Solution

I. Product Application:

ZX-317 is a slag-free, medium-temperature zinc-manganese series phosphating solution designed for corrosion-resistant treatment of steel surfaces. It rapidly forms a uniform and dense phosphating film on steel components, characterized by a black-gray appearance, fine and even texture, excellent corrosion resistance (copper sulfate drop test can exceed 10 minutes), and strong wear resistance. It is particularly suitable for high-quality black phosphating applications such as bearing cylinder liners, piston rings, automotive and motorcycle parts, and various mechanical components. Phosphated workpieces can also serve as a pre-treatment for coating, enhancing adhesion between paint/plastic layers and the steel substrate, preventing issues like paint peeling, flaking, or poor adhesion after spraying.

II. Product Advantages:

1. The phosphating film formed on steel surfaces treated with this product is dense and highly corrosion-resistant, improving the bonding strength between the substrate and coating;

2. This product contains no toxic substances, produces no harmful gases, is recyclable with a long service life, offers low comprehensive costs, and is easy to use.

III. Operation Process:

Workpiece after degreasing and oil removal → rinse thoroughly with water → pickling for rust removal → rinse thoroughly with water → immersion in XF-416 surface conditioner → treatment with ZX-317 phosphating solution → hot water rinse → rinse thoroughly with water → optional immersion in rust preventive oil, sealer, or direct spraying
