In daily life and industrial production, the problem of surfaces being stained and eroded by rain has always troubled people. Scenarios such as car bodies covered with water marks after rain, glass surfaces accumulating dust over time, and public facilities being defaced by graffiti are common occurrences. Now, a new type of organopolysilazane coating material has emerged with its magical "hydrophobic and anti-fouling" properties, equipping various object surfaces with an "invisible umbrella" and making cleaning and maintenance easy and efficient.
The core magic of this material lies in its super hydrophobic performance. After curing, the formed coating has a contact angle of 100°-105°, just like the surface of a lotus leaf in nature. Water droplets falling on it instantly condense into spheres and roll off naturally without leaving water stains. This "lotus effect" allows rainwater to wash away dust, mud spots, and other stains when冲刷ing the surface, significantly reducing cleaning frequency. Experiments show that cars coated with this material only need simple wiping to regain cleanliness after driving in the rain, and glass surfaces can remain transparent and clear even after long-term exposure.
The anti-fouling ability is equally amazing. It forms a dense protective film on the surface, making it difficult for various stains to penetrate and adhere. Whether it is marker graffiti, oil stains, or daily dust, they can be easily wiped off, making it especially suitable for protecting walls and furniture in public places such as schools and shopping malls. In the field of automotive coatings, it not only enhances the brightness of the car body but also endows the surface with excellent scratch resistance, reducing the number of car washes while keeping the vehicle in a new state for a long time.
Construction convenience is another major advantage. The material itself has extremely low viscosity (only 10-40cp), making it as easy to operate as a thin solution. Whether it is spraying, brushing, dipping, or simple wiping, it can evenly cover the surface. More importantly, it has strong compatibility and can closely bond with various substrates such as metal, glass, plastic, ceramics, and paint films, forming a firm connection through special molecular reactions. The adhesion tested by the cross-cut method reaches level 0, solving the problem of traditional coatings being prone to peeling and falling off.
The flexibility of curing methods further expands its application range. It can be cured naturally at room temperature, with the surface drying in 30-50 minutes and full curing in 24 hours. If quick put-into-use is required, the heating curing mode can significantly speed up the process: curing can be completed by baking at 120-180℃ for 2-6 hours, or even in just 10-20 minutes at 200-250℃, meeting the production rhythm needs of different scenarios. The cured coating has a maximum hardness of 7H, which is not easy to scratch during daily friction, and its durability is far superior to ordinary protective coatings.
From car bodies and architectural glass to furniture and home appliances, from industrial equipment to public facilities, this magical coating is providing efficient protection solutions for various industries with its water-repellent and stain-resistant properties. It not only reduces cleaning and maintenance costs but also extends the service life of objects, allowing various items to truly "have a built-in umbrella" and stay clean and new at all times.
