3. Introduction to the performance of paint protective film
(1) Excellent self-healing ability: using a special anti-oil self-healing coating design, surface scratches can be self-repaired, protecting the car's appearance as perfect as new.

(2) Protect the original paint surface: prevent sand, dust, acid rain, bird droppings, leaves and other damage to the paint, reduce the cost of beauty care; at the same time, it will still look new after many years and increase the price of the second sale of the vehicle.

(3) Improve the brightness of the paint surface: increase the brightness of the original paint surface by 30%, and increase the beauty of the vehicle's appearance.

(4) Prevent malicious scratches: The paint protective film has excellent wear resistance and puncture resistance, which can effectively protect your car from malicious scratches when parking, and can also prevent pets from scratching.

(5) Efficient UV blocking ability: The paint surface protective film has an excellent UV blocking function, which can effectively improve the UV aging resistance of the paint surface, and it is not suitable for discoloration or yellowing.

(6) Colorless and transparent: super gloss retention and excellent permeability, integrated with the car body, does not affect the natural color of the paint.

(7) Green and environmental protection: using environmentally friendly substrates, the product does not have any side effects on the painted surface, human body and nature.

This product is mainly used for the protection of the paint surface of the entire car body, and can also be separately applied to the bumpers, door edges, side mirrors, fenders, door handles, hoods and other parts that are vulnerable to damage.

4. Analysis of the pros and cons of nano-ceramic thermal insulation glass window film?

(1) Heat insulation effect

In the market, the infrared blocking effect is usually used to indicate the thermal insulation effect of the window film (the thermal insulation rate is not accurate). The difference in the blocking effect of nano thermal insulation materials in different infrared bands is measured by portable instruments, and the measurement points are divided into 950nm and 1400nm. , Even if it is selected in the same band, different portable instruments will still have test differences, and the test data is only for reference. Accurate measurement should be measured with a full-band spectrophotometer, and its thermal insulation effect should be compared with the data of the total solar energy blocking rate and the shading coefficient under the premise of similar visible light transmittance.

(2) apparent performance

The dispersing solvent, nanometer particle size and compatibility with resin of nano-ceramic materials affect the apparent blue haze and stabilization effect of the product. Even if the same insulation material is obtained, the apparent performance of the product may be different due to the different structure design, coating process, and use of the substrate.

(3) Stable performance
The finer the nano-inorganic thermal insulation material is dispersed, the better the appearance will be, but the easier it is to be unstable; some manufacturers add organic absorbing materials to increase the data to ensure the infrared blocking data, but the later data attenuation is serious, reducing the heat insulation and energy saving effect, color and The light transmission will also change.
