On rainy days, have you wondered why you need to strain your eyes just to have a better look at the road ahead, even with the assistance of wipers? Driving in the rain, especially, after dark can be quite a challenge.
As the rain pours, water droplets spread over the windscreen, thus hampering the visibility. This reduction in visibility may impair the judgement of the driver, which increases the possibility of accidents.
Water repellence pattern
Due to its polarity nature, water has high cohesion and adhesion properties. On a clean and smooth surface, the water spreads to form a thin film. This happens when the adhesive forces are stronger than the cohesive forces. Hence, when it rains, it is common to see water droplets spreading over glass surfaces.
On the other hand, when a droplet of water lands on a lotus leaf, it beads up and rolls off the leaf surface without leaving a trace of water behind. Along the way, it washes away any dirt.
This self-cleaning property fascinated scientists for a long time until recently, when scientists realised that this peculiar behaviour is due to the nanostructures present on the surface of the lotus leaf. They termed this high water repellence phenomenon as super-hydrophobicity.
Technical applications
Some nanotechnologists have developed treatments, coatings, paints, roof tiles, fabrics and other surfaces that can stay dry and clean themselves in the same way as the lotus leaf.
This can usually be achieved using special fluorochemical or silicone treatments on structured surfaces or with compositions containing micro-scale matter. Super-hydrophobic coatings comprising Teflon microparticles have been used on medical diagnostic slides for over 30 years.
It is possible to achieve such effects by using combinations of polyethylene glycol with glucose and sucrose, or any insoluble matter in conjunction with a hydrophobic substance.
One example of a product with super-hydrophobic self-cleaning properties is the NV RainGuard.
NV RainGuard
NV RainGuard is a product specialty of Nick & Vin Autoshine, a local firm specialising in super-hydrophobic nanotechnology.
The product combines nanotechnology and chemical treatment to produce super-hydrophobic coating solution for water repellent application. A cost effective spray solution designed for glass, metal and ceramic surfaces, NV RainGuard's coating is translucent and has a large contact angle for easy rolling of water droplets. It has been tested for outdoor durability and is able to withstand tough weather conditions.

Advantages of NV RainGuard
NV RainGuard uses advanced Germany nanotechnology to significantly improve the quality of glass surfaces. By bonding with the glass surface on a sub-molecular level, NV RainGuard protects it from micro-scratches caused by environmental factors while simultaneously giving the glass hydrophobic properties that stop water from collecting on the surface and impeding visibility.
With the ultra-smooth surface NV RainGuard creates, water that comes into contact with the glass forms into beads more quickly, instantly sliding off the glass surface. This ensures maximum clarity for the glass surface, even in extreme weather conditions.
A breakthrough innovation that will not peel or compromise the glass' original optical properties, NV RainGuard is an indispensable and long-lasting enhancement for any glass surface - from windows to windshields, outdoor glass display panels to glass canopies.
When applied to car windscreens, NV RainGuard not only improves visibility, but it also prevents wiper marks on windscreen surfaces as well as assists in reducing glare from other vehicles' headlights at night. Most importantly, the safety of driving during heavy downpours is increased.
The NV RainGuard can last permanently on all window surfaces except on the front windscreen, which may deteriorate depending on wiper usage.
Installation prices for the NV RainGuard on vehicles start from $140 for a medium-sized car and the whole installation process only requires 2 hours. If there is a request to remove water spots from the windows, additional charges will apply.
