A number of anti-fog polycarbonate panels which are available in the market provide excellent longevity and durability. These panels are mainly used in most personal protective equipment items such as in sport and display panels. They offer high optical clarity even in the high humidity environments. These products feature the following key properties: chemical resistance, flexibility and optical clarity.

The most common panels include the hard coated anti-fog polycarbonate panels which are durable with a strong surfaces which are scratch proof. Apart from the optical clarity, they have an easy to clean surface which resists scratching. They can retain anti-fog properties for a very long period of time even after they have been cleaned severally.

The anti-fog polycarbonate panels are coated with a thin permanent coating with the ability to spread the moisture in the air evenly. This process ensures that this moisture do not form droplets on the surface of the panel. The good thing about this coating is that it eliminates the need for other products such as the temporary anti-fog sprays, solutions or even wiping the surface of the sheet which is expensive and tiresome.

The anti-fog coating do not affect the degree of light transmission through these panels. They have been designed in such a way that there is no increase in haze or loss of light transmission.


Anti-fog Polycarbonate Panels


Polycarbonate panels are designed for a number of applications thus, it is prudent that they be taken through a number of tests to ensure that meet the required criteria. This is because they should be able to resist fogging under all conditions.  Some of the most common test include:

The breath fog test; this test is carried out to ascertain that no fog forms when someone breaths directly on the anti-fog polycarbonate panels since it will reduce the optical clarity of the panel. This is an essential and the simplest test which you can conduct when buying anti-fog products such as helmets.

The after shower test; a good anti-fog panel should remain fog free after it has been exposed to hot or warm moist air in a shower. It’s a simple test too which can be conducted cheaply. This test should last for about 45 minutes.

The hot water test; this test is carried out using vapor from hot water with a temperature of about 175°F. No fog should form after the sheet under test is exposed to this condition.

The freezer test; no fog should form when the anti-fog polycarbonate panel has been exposed to a humid environment.

Immersion test; this involves inserting the panel to be tested in water for more than 24 hours to determine whether it can retain this essential property.

These tests are very simple and crucial when determining the efficiency of these panels. In fact, you don’t need to own any sophisticated machine to make viable conclusion about a product as far formation of fog on a panel’s surface is concerned. The optical quality of panel will depend on the outcome of tests.
