Xn-501a antifogging coating is a kind of nano coating attached to PC / PET / PMMA and other substrate surfaces to prevent the generation of fog. It is characterized by simple coating, water-based environmental protection, rapid formation of antifogging effect, friction resistance, high temperature and humidity resistance, and is a super hydrophilic antifogging coating.
Comparison of water drop angle between ordinary lenses and those coated with antifogging super hydrophilic coating
Xn-501a nano antifogging coating rapidly forms a film on the surface of the lens. Because of its super hydrophilic characteristics, it increases the surface tension of water, and water can not form water droplets on its surface, but a layer of water film, which fundamentally prevents the formation of fog.

Characteristics of antifogging coating
1、 Flexible process and easy operation (simple operation only)
Coating process: spray coating, dip coating, spray coating and roller coating
1. Hand coating:
Before use, thoroughly clean the surface of the substrate, dip the dust-free cloth in the nano antifogging coating, evenly smear the surface of the substrate, bake at 60 ℃, the surface finger touch curing is about 3 minutes, and the performance reaches more than 95% after 24 hours.
2. Spraying process:
The basic principle of spraying with equipment is to atomize the antifogging liquid and make it evenly adhere to the surface of lens substrate, and then conduct conventional heating reaction. The spraying process of the equipment will have different working principles due to different equipment. The basic principle is to atomize the antifogging liquid through the nozzle, so that it can fully adhere to the molecules on the surface of the substrate with few particles, and heat it to fully react and solidify.
3. Spin coating process:
It is more uniform to use special high-speed lens coating machine with peristaltic dispensing machine.
4. The optical lens can be coated with the rotating paint machine commonly used in the factory.
Qingshan new material has anti fog coating products for glass and optical glass lenses, as well as anti fog coating products for acrylic plastic lenses, and has a variety of anti fog treatment products such as drying type, normal temperature self drying type and so on.
2、 More than 200 times of alcohol resistant wiping, more than 240 hours of water resistant, more than 80 hours of boiling, 1 hour of service life up to 2 years
1.50 saturated steam, 5cm distance, fumigation for 3 seconds without fogging, film is bright
2. After fumigation, wipe clean, fumigate again, repeat the test for 100 times, and the anti fog property does not decay
3.25 bubble for 2 hours, fumigation for 20 seconds without fogging, and the film is bright
4. - 352 hours later, heat it to 808 hours, circulate it for 3 times, with no attenuation of antifogging property
5.25 keep the antifogging effect for 240 hours, and the film is bright
6. Strong alcohol resistant wiping ability, repeated wiping for more than 200 times, no less anti fog performance
