How Aluminum Silver Paste Enhances Weather Resistance in Plastic Coatings

At Five New Materials, we understand that enhancing the durability of plastic coatings is paramount. Our aluminum silver paste contributes significantly to weather resistance through the following mechanisms:

Inherent Properties: The high reflectivity of the aluminum powder in our silver paste effectively reflects UV radiation. これは reduces the direct exposure of the plastic substrate to UV rays, minimizing UV-induced degradation and fading, thereby improving the overall weather resistance of the plastic coating.

Encapsulation Treatment:

• Silica Encapsulation: We utilize silica encapsulation for our aluminum silver paste, which significantly enhances its water and acid-alkali resistance, consequently boosting weather resistance. For example, Yantai Yunfan’s Silver Arrow Yantai waterborne floating aluminum paste, treated with silica encapsulation, demonstrates excellent weather and acid-alkali resistance.
• Resin Encapsulation: The paint film can maintain long-term gloss and color stability under extreme environmental conditions through innovative resin encapsulation technologies, such as those employed in Silver Arrow aluminum silver paste. これは protects the substrate from UV radiation and salt spray corrosion, significantly improving the coating’s weather and corrosion resistance.

Enhanced Compatibility with Resins:

Selecting the appropriate resin system that exhibits excellent compatibility with our aluminum silver paste allows the paste to exert its properties within the plastic coating better, enhancing its weather resistance. For instance, the aluminum silver paste used in fluorocarbon coatings is compatible with fluorocarbon resins, significantly improving the coating’s durability.

Addition of Additives:

We can further modify our aluminum silver paste by incorporating specific additives like nano-bentonite and multi-walled carbon nanotubes to enhance weather resistance. For example, in methods to improve the gloss effect of weather-resistant aluminum silver paste, the addition of nano-bentonite and multi-walled carbon nanotubes, followed by specific processing techniques, enables the aluminum silver paste to withstand temperatures of 530-550°C and resist corrosion for 200 hours while maintaining good metallic gloss and hiding power.
