Advantages of Medium Temperature Zinc Series

 
 

Enhanced Corrosion Resistance
One of the primary benefits of medium temperature zinc phosphating solutions is their ability to provide enhanced corrosion resistance. The crystalline structure forms a robust barrier that protects metal surfaces from moisture, salt, and other corrosive agents. This is particularly important in harsh environments where metals are exposed to the elements.

 
 

Improved Paint and Coating Adhesion
The textured surface created by medium temperature zinc phosphating solutions promotes strong bonding between the metal and subsequent coatings. This reduces the risk of peeling, chipping, or flaking, ensuring a long-lasting finish.

 
 

Cost-Effective Protection
medium temperature zinc phosphating solutions offer long-lasting protection at a reasonable cost. By reducing the need for frequent maintenance and replacement, they provide significant economic benefits to industries.

 
 

Eco-Friendly Options
Modern zinc phosphating processes are designed to minimize environmental impact. They use eco-friendly solutions and reduce waste, making them a sustainable choice for metal finishing.

Precautions for Use of Medium Temperature Zinc Series

● Before blackening, we must do oil removal and rust removal treatment, and play the role of surface acidification. In the middle of each step, we must wash with water, and dry in time after blackening.


● Blackening time must be controlled well, reach Yan 85%~95% to take out, too long and too short are useless.


● All operations must wear gloves, pay attention to ventilation.

 

Application Method of Medium Temperature Zinc Series Coating
 
 

Surface Cleaning

Ensures contaminants like dirt, grease, and oxides are removed for better adhesion.

 
 
 

Phosphating Bath

Metal parts are immersed in a zinc phosphate solution, where the chemical reaction forms the protective layer.

 
 
 

Rinsing and Drying

Removes residual chemicals and prepares the surface for subsequent coatings like powder coating.

 

 

Packaging and Shipping

 

 

Packaging

For cutting liquid in small packs, in general, we pack in plastic bottles 800 ml, 1 liter and 4 liters volume. These bottles are then packed inside a carton box. If you require special pack such as metal can, it can also be done accordingly for which you need to contact us for more details.

Shipping

It will be better if your have your own forwarder to take care of the shipping.If not, our professional forwarder can help you.

DHL/FedEx/UPS/TNT/EMS/By sea and so on are optional for sample. We can send goods by shipping ways you want.

For sample order, we suggest express, shipping time is about 5-7 days.

For large order, we suggest cheaper ocean shipping. Shipping time depends on your port and quantity. For LCL shipment volume over 1.5CBM or full container, It is the most economical mode of transport.

FAQ

 

Q: What is the process of phosphatization?

A: Phosphatization, or phosphatic fossilization, refers to the process of fossilization where organic matter is replaced by abundant calcium-phosphate minerals.

Q: How long does phosphate coating last?

A: The lifespan is dependent on the aggressiveness of their environment. Phosphate Coatings- 3 to 10 years. Typically used in undemanding environments as a base for painting or a standalone protective layer.

Q: What is the color of phosphating process?

A: Pale to dark grey manganese, zinc or zinc/calcium phosphate layer consisting of secondary and tertiary manganese, zinc or zinc/calcium phosphates. Securely anchored on the base metal.

Q: How do you remove phosphate coating?

A: Traditional phosphate removal methods rely on chemical strippers like hydrochloric and sulfuric acid. Other strongly alkaline and chelated solutions are just as dangerous. If you want to get rid of chemicals during phosphate coating removal, laser cleaning may be the solution you're looking for.

Q: How environmentally friendly are phosphating agents?

A: Traditional phosphating agents contain phosphates and nitrites, and improper wastewater treatment can easily cause eutrophication of water bodies. Currently, environmentally friendly phosphating agents have been developed, such as nitrite-free accelerators and low-phosphorus/no-phosphorus formulas. Some companies use closed-loop water treatment systems to reduce emissions.

Q: What are the temperature requirements for phosphating?

A: Room temperature phosphating: 15-40℃, low energy consumption, but long processing time and thin film layer.
Medium temperature phosphating: 50-70℃, fast processing speed, stable film performance, and wide application.
High temperature phosphating: 80-95℃, thick film layer, strong corrosion resistance, but high energy consumption and easy scaling.
