Anti-fog products

Good wettability of water on the surface of a material indicates that the material is hydrophilic; poor wettability indicates that the material is hydrophobic. Water contact angle is generally used as a measure.
Products

Anti-fog product with super hydrophilic properties, water vapour can be spread evenly on its surface, effectively preventing the formation of water mist.

Hydrophilic interface anti-fog principle

In the presence of a temperature difference, condensate condenses into a layer of small, fine water droplets that adhere to the transparent interface. Light is scattered and irregularly refracted at the water droplet interface, resulting in a blurred visual image, which is called "fogging". On the other hand, on the superhydrophilic interface, the condensate automatically spreads into a film of uniform thickness, allowing light to pass through in the same refractive path without affecting the visual image.

Superhydrophilic/anti-fog material SW001

Products

SW-001 is an anti-fog product, colourless and odourless, which mainly forms a film on the surface of glass or resin by wet-coating, using its super-hydrophilic properties, so that water vapour can be spread quickly on the surface of the substrate to form a uniform water film, to achieve anti-fog effect. The product is suitable for optical lenses, radar masks, headlights, visible windows and other scenes.

Product Features

- Excellent anti-fog performance, water contact angle <5°;
- Strong adhesion, no peeling of 3M tape in 100-g test;
- Excellent friction resistance, dustless cloth dipped in 75% alcohol, in 500g load back and forth friction 15,000 times, anti-fog grade to maintain the same level 1;
- Nano-level transparent coating, high transmittance rate, does not affect the appearance of the product;
- Safe, environmentally friendly, non-toxic to the human body.

Application process

- Depending on the substrate, choose a suitable pre-treatment process to expose the substrate surface to a fresh SiO2 surface;
- Soak in anti-fogging solution for 3min at room temperature (25-30°C); 
- According to the substrate, select the suitable heat treatment parameters (100-150°C) and carry out heat treatment;
- Clean the surface with deionised water and dry the surface.
