Automotive Silicone coated wiper technology

For drivers, whether the driver’s vision is clear is a matter of life and death, so it is very important to use a good pair of wipers when driving.

A safety survey shows that the traffic accident rate caused by aging wiper blades when driving a car in rainy days is many times higher than usual. In other words, the seemingly insignificant wipers on weekdays either become a lifesaver or the culprit at a critical moment. So, choosing a durable and good wiper is very important. Because wipers are not only used frequently, but also wiper blades have to face high temperature exposure, cold winter, wear, oxidation, acid rain corrosion and wind erosion.

Working principle of silicone coated wipers

Silicone coated wipers are a new type of wipers that use special technology to form a water-resistant film on the windshield.
Using the original special water-repellent film spraying process, adding new silicone rubber and “three-dimensional silicone element polymer”, a special protective film containing lubricating and water-repellent components can be formed on the windshield on rainy days. When the wiper is working, the silicone strip contacts the glass surface. On the one hand, the characteristics of silicone can quickly scrape off the rain. On the other hand, during the wiping process, the effective ingredients in the silicone will continuously replenish and strengthen the coating on the glass surface, so that the glass maintains good water-repelling performance.

Advantages of silicone coated wipers

Clear vision: It can automatically turn rain into raindrops on the glass surface and slide down quickly, effectively reducing the contact area between raindrops and the glass surface, controlling the refraction of light produced by raindrops, ensuring that drivers have a clear line of sight on rainy days, and greatly improving the safety of driving on rainy days.
Super durability: Compared with natural rubber, silicone components have better heat resistance, UV resistance, ozone resistance and wear resistance. The service life is more than 3 times that of natural rubber, and the initial rain-wiping effect can be maintained for a long time.
Quiet and stable: Due to the characteristics of silicone and the coating of friction reducers, the wiper is more stable when wiping, and will not produce shaking or noise. Even in light rain, it can ensure silence and will not jump, which can provide drivers with a quiet and comfortable driving environment.
Protect glass: Ultra-soft silicone rubber can completely wipe off rain, mud and other impurities, and can effectively protect the glass surface during the wiping process, reducing scratch damage.
Environmentally friendly and harmless: Silicone wipers can be burned as combustibles after being discarded, and no harmful substances will be produced after burning, which is beneficial to the environment.

So why do car buyers now choose coated silicone wipers instead of ordinary rubber wipers?

Technical PK

When silicone coated wipers rub against the car window glass, they will release a unique lotus leaf drainage factor to form a magical drainage film, making the field of vision clear and lasting like new. The car is still silent when driving at a speed of more than 80 yards, and there is no need to turn on the wipers, and the rain will automatically roll off.
Ordinary rubber wipers do not physically release special drainage materials. After about three months of use, problems such as unsatisfactory scraping and many water marks will occur, which seriously affects driving safety in rainy and snowy days.

Service life PK

Silicone coated wipers are extremely wear-resistant and are not afraid of the impact of harsh environments. Their service life is more than twice that of ordinary rubber wipers!
After three months of wiping, the lips of ordinary rubber wipers will be severely worn and the outer surface of the wipers will crack, which will lead to poor rain wiping effects.

High and low temperature resistance PK

Silicone coated wipers can effectively resist sun aging and are born to fight high temperatures!
At extremely high temperatures of 80°C, there is no obvious softening and aging.
Effectively resist freezing and hardening, born to fight low temperatures!
At extremely low temperatures of -50°C, there is no obvious hardening and aging.
Ordinary rubber wipers often directly scrapped in the face of extreme high and low temperature challenges!

Environmentally friendly material PK

The coated silicone wipers use imported food-grade silicone raw materials, which belong to a polymer structure. After the end of their service life, they will decompose into silicon elements and return to the land, without causing land pollution.
The rubber raw materials used in ordinary rubber wipers will decompose harmful substances after the end of their service life, causing a certain degree of pollution to the environment.

Disadvantages of silicone coated wipers

Of course, silicone coated wipers also have disadvantages.
Interference with night vision: The silicone oil coating on the glass will increase the surface tension of the glass. Under the illumination of street lights at night, small water droplets will refract the light, forming a white mist on the glass, which will interfere with the driver’s night vision.
High price: To ensure performance, silicone wipers require strict design and testing processes during the research and development and production process, resulting in their prices usually being higher than ordinary rubber wipers.
High cleaning and maintenance requirements: When using silicone coated wipers, wiper essence cannot be used, otherwise it will affect the coating effect. At the same time, the silicon element on the surface of the glass will form a mixture that is not easy to fall off when in contact with dust for a long time, and the glass needs to be deep cleaned regularly to maintain a good field of vision.

Novoflow specializes in the production of silicone coated wipers and rubber wipers, and also develops and produces graphene wipers. Relying on the core technology and production experience of wiper manufacturing, our silicone coated wipers only need to be dry-brushed on the glass for 3 minutes to form a super water-repellent coating. When driving at high speeds, rainwater turns into water droplets and bounces up. Even without using wipers, you can maintain a clear view, solving 90% of driving safety problems.
