If you use glasses, drive a car or generally use any equipment that makes use of glasses, mirrors or transparent plastic contraptions, you must have had your own battles with mist. It descends all of a sudden, clouding your vision and rendering your glasses or windshields almost unusable.
It can be quite frustrating, especially when you have to get a rag, thereby stopping whatever important activity you were engaged in.
What Are Mists
A mist is what happens when small droplets of water are suspended in the air. Physically, it is an example of what scientists (a race of ultra-intelligent beings who walk around in white coats) refer to as dispersion. Mists mostly occur where moist, warm air is suddenly cooled such as in exhaled air in winter.
Mists can also occur naturally when humid air comes into contact with surfaces that are much cooler than it. An example of this is what you see when you splash water on a hot surface.
As with many other types of suspensions, the formation of mists is greatly aided by the presence of nucleation sites. Even rather unusual sources, like small particles from volcanoes, can, given right conditions, trigger the formation of mists and make mirrors look foggy.
Effects of Mists
Because of the fact that mists often form on critical surfaces used for optical aid such as glasses, binoculars and even windshields, it can become a big issue if not dealt with correctly. For example, a driver driving with mist on his windshield would be visually impaired and therefore would be a danger to himself and to other drivers.
Also, a scientist in the field or in a lab can miss important scientific data due to impaired vision.
Mist formation on these surfaces isn’t just a slight inconvenience, it is a problem. Luckily, Advanced Nanotechnologies has developed the perfect solutions to permanently remove these hindrances from your glass products.
Crystal Clear, No Mist-Takes.
Advanced Nanotechnologies has created solutions that will prevent the condensation of water on the glass surfaces of any of your products, thereby putting a stop to the mist disaster. This improvement instantly makes your products more attractive to customers than other products that could be affected by mists.
As long as customers value useful innovation to improve their life and work, applying these solutions to your products will improve your market share.
These solutions are now widely used on transparent plastic or glass surfaces used in the optical application. This, of course, includes spectacles, goggles, and windshields. The treatment works by making sure that surface tension is minimalized, and thereby ensuring a non-scattering film of water instead of a single droplet.
This treatment usually works by the application of surfactant film or by the creation of hydrophilic surface.
These agents can be useful for a plethora of reasons. Some of these include underwater diving, misty windshields, fogged camera lenses and/or binoculars amongst others.
Mists, for the most part, are different from fogs only on the basis of thickness and location. Fogs are similar to mists but are denser than mists. Therefore most anti-fogging treatments can be used to demist the surfaces of your products.
1. Anti-mist Nano-coating
A stellar example of such treatments has to be The Anti-Fog treatment X-Fog, developed by Advanced Nanotechnologies. This treatment is one of the company’s patented technologies that have produced exceptional results in a wide variety of environments and applications.
The treatment effectively stops all surface condensation that could happen as a result of large differences in interior and exterior temperatures, the major causes of mists and fogs.
It is essentially a permanent nano-coating for plastic and glass substrates with anti-mist materials that leave surfaces free of mists and fogs. This coating works perfectly on eyeglasses, safety glasses, goggles, mirrors, automobile parts, helmets, diving masks, etc.
AN also offers anti-mist lens filters for cameras used for motion picture recording. These filters expand the shooting angle possibilities of these cameras and have been used in extreme conditions.
The transparent filter is a nanostructured anti-fog coating that helps them prevent mist formation on optical instruments.
Anti-mist coating applications
Ultra-high vacuum machines (UHV) that are based on Physical Vapor Deposition (PVD) are used to apply this nano-coating technology. The machines are used to apply a permanent nano-thin layer of material to the surfaces. Maintenance is easy as the surfaces can be quickly cleaned using a wipe that has been developed for that purpose.
2. Anti-mist Sprays
These sprays are mostly packaged into bottles and are also common. The spray guns atomize the solution into fine sprays. The solution spreads uniformly on the surface when applied to reduce excessive wastage. Upon application via the nozzle, small particles from the solution stick to the surface it is applied on.
Anti-mist sprays application
Most anti-mist sprays in this category can have very simple or complex applications depending on the ingredients used. However, the basic application is to clean the surface, follow additional direction by the manufacturer, apply the anti-mist solution to the surface, and finally drying the surface. Some manufacturers require you to apply the solution to the surface one more time after it dries.
Choosing the Right Technology
The anti-mist technology you choose must be effective at high humidity and high-temperature environments. Full transmittance is another factor that must be taken into consideration for visibility purposes, especially for visors, glasses, and goggles.
It must also be compatible with anti-reflective coating. Nano-coating embodies these factors as well as delivering a permanent coat onto your surfaces. This removes the problem of re-applying every couple of hours.
Spray solutions are not as permanent as nano-coating but they also have their advantages. Some of the sprays are manufactured from natural, biodegradable ingredients and they can be more sustainable. They can also be easy to apply especially on small surfaces for use in the home.
Consider the type of materials you want to apply it on as some anti-mist agents can be counter-productive on glass surfaces. If you have a product line, nano-coating is a good option to ensure lasting effects and easier usage for your customers.
Mist prevention has been demystified and the solutions are accessible. Before you choose an anti-mist technology, consider your product type and the environment where it will be used. Anti-mist sprays are suitable for home use and temporary situations while nano-coating is recommended for commercial production or more permanent use.
