ZINC PHOSPHATE AND ITS CORROSION RESISTANCE

1. Definition

Right from the name, the definition of the two-component metallic coating is extremely easy to understand: It is the coating applied to metal that includes 2 main components: Paint and Curing agent.

• Paint: is acrylic resin or epoxy resin combined with super fine color particles, surfactants, additives, etc to protect and increase the aesthetics of the product.
• Curing agents: When mixed with paint, they will create a durable bonding "network" for the metal surface and promote the role of each component.

The two-component metallic coating can be an epoxy-based two-component metallic oil paint (two-component Epoxy coating) that provides absolute protection for the machine's surface, or a two-component anti-rust Epoxy coating applicable to metal surfaces that get frequent impacts from the external environment.

2. Advantages and disadvantages of two-component metallic coating:

Two-component metallic paint is widely used in construction, interior, and exterior decoration due to the following advantages:

• High hardness, good heat resistance, good corrosion resistance, and impact resistance 
• Anti-oxidation, anti-rust
• Anti-mold, anti-dust, easy to clean 
• Good adhesion and high color durability

Besides, the disadvantages of this paint line are:

• Slow painting construction due to the mixing process
• Should be used in 4-6 hours after mixing for the best quality

3. Application of two-component metallic coating

Despite the high cost compared to single-component paints, the two-component metallic coatings are still be commonly used to protect steel structures from extreme weather due to their advantages. 

Hence, manufacturers are constantly improving their quality of and produce new coating products suitable for each type of materials and customers’ requirement:

• Two-component galvanized paint: Suitable for zinc surfaces
• Two-component iron paint: For iron and steel metal surfaces without zinc coating
• Two-components primer: Protect and cover metal surface defects
• Two-component rustproof paint: Protect metal against corrosion and oxidation
