The outdoor advertising fabric in the coastal areas of East China adopts PVC coating technology, mainly for the following reasons:

1. Weather resistance and UV resistance

The coastal areas of East China have abundant sunshine and strong ultraviolet radiation. After special treatment, PVC coated cloth can effectively resist ultraviolet radiation, is not easy to fade, and can prevent material brittleness, making it suitable for long-term exposure to outdoor environments. By adding additives such as anti UV agents, the weather resistance and UV resistance of PVC coatings can be further enhanced.

2. Salt spray corrosion resistance performance

Coastal areas have high humidity and salt content, which can easily cause corrosion to materials. PVC coated cloth has good chemical corrosion resistance and can resist the erosion of salt spray, thereby prolongingAdvertising clothThe service life. Although the anti salt spray corrosion performance of PVC coating may not be as good as PVDF coating, its salt spray resistance can also meet the basic needs of outdoor advertising fabrics through special processes and additives.

3. Waterproof and self-cleaning performance

pvc coatingCloth has excellent waterproof performance and can effectively block the penetration of moisture. At the same time, its surface is smooth, not easily contaminated with dust and stains, and has good self-cleaning performance. Dust and stains are easily washed away by rainwater, reducing the workload of cleaning and maintenance.

4. Strength and durability

PVC coated fabric has high tensile, tear and peel resistance properties. The base fabric is usually made of high-strength polyester fibers, which, when tightly combined with PVC coating, can withstand strong wind and external forces, making it suitable for outdoor advertising fabrics that require long-term exposure to harsh environments.

5. Cost effectiveness

The PVC coating process is relatively mature, with low production costs and a wide range of material sources. Compared to other high-end coating materials such as PVDF, PVC coating can be provided at a more economical price while meeting basic performance requirements, making it suitable for large-scale production and widespread application.

6. Environmental friendliness

With the advancement of technology, many PVC coated fabrics using environmentally friendly processes and raw materials have emerged, which can reduce the impact on the ecological environment. Some brands have even started developing recyclable PVC materials to achieve sustainable product development.

7. PVC coating anti salt spray corrosion test

In order to verify the salt spray corrosion resistance of PVC coated cloth in coastal areas, salt spray corrosion resistance tests are usually conducted. By simulating a high salt spray environment, the corrosion resistance of the coating is tested to ensure its reliability and durability in practical use.

In summary, PVC coating technology has been widely used in outdoor advertising fabrics in the coastal areas of East China, mainly because it can meet the requirements of weather resistance, UV resistance, waterproofing, salt spray corrosion resistance and other properties of outdoor advertising fabrics, while also having high cost-effectiveness and good environmental protection.
