Many buildings are complex in shape and high in height, so the human and material cost of cleaning once is very high.We often see “spiderman” outside buildings, and safety at high altitude is a big problem.

Now the haze is so serious, the air quality is low, and the surface is more vulnerable to pollution.So there is no such a material, can achieve self-cleaning.

As we mentioned earlier, color coated panels are now used in many buildings because of their superior performance and low cost.There is a special variety of color coated, we call it will give their own bath color coated plate – self-cleaning color coated plate.

1. Self-cleaning polyester (PE)

2. Self-cleaning silicon modified polyester (SMP)

3. Self-cleaning high weathering polyester (HDP)

4. Self-cleaning fluorocarbon (PVDF)

Above four kinds of coating from top to bottom weather resistance is better and better, of course, the price is also more and more expensive.

Features and applications

1. Excellent decorative performance

2. Special finish design to achieve self-cleaning function

3, according to the different environment, there are a variety of topcoat to choose
