Is Car Rain Repellent Useful?

[LaLouis]

Car rain repellent is very useful for driving in rainy weather. It utilizes the hydrophobic principle of nanomaterials to prevent rainwater from forming a film on the car's glass surface, thereby improving the efficiency of windshield wipers and significantly enhancing driving safety during heavy rain. Below is relevant information about car rain repellent: 1. Car glass rain repellent forms a nano/micron protective layer on the glass surface; this protective layer has a hydrophobic (repellent) effect. As a result, when rainwater falls on the glass surface, it automatically contracts into droplets and slides off the glass. 2. Although high-end car glass comes with a rain-repellent coating from the factory, it quickly wears off or disappears due to the constant friction of windshield wipers. This is why rainwater tends to stick to the glass during rainy days. 3. Car glass rain repellent primarily alters the surface properties of the car glass—changing it from hydrophilic to hydrophobic—thus achieving the purpose of rain repellency. The advantage of this rain-repellent mechanism is its long-lasting effect, as the protective layer is not washed away by rainwater.
