In urban construction and management, the neat appearance of buildings is often challenged by graffiti, and the all hydrogen polysilazane liquid coating material IOTA PHPS provides an excellent protective solution for this.
IOTA PHPS， The Chinese name is inorganic (fully hydrogen) polysilazane, also known as nano hydrophilic and stain resistant coating material. As a coating specifically developed for anti graffiti needs, it has many significant advantages.
From the perspective of product characteristics, it has good solubility and can easily blend with various suitable solvents, making it convenient for construction personnel to adjust according to specific construction scenarios, ensuring uniform coating on building surfaces of different materials and shapes. The curing time is relatively short, and curing at room temperature for more than 7 days can achieve the desired protective effect. This can effectively reduce the risk of project delays for large-scale construction projects. Moreover, there are various curing methods available, whether it is conventional natural drying curing or accelerated curing under specific temperature and humidity conditions, which can be flexibly selected.
In terms of technical parameters, it appears as a colorless and transparent liquid, which does not visually interfere with the original appearance of the building. It can perfectly maintain the original style of the building, with a solid content of 20%. The solvent used is n-butyl ether, and the liquid density is between 1.16-1.31 g/ml. These parameters ensure its good construction operability and stability.
When it comes to coating performance, this is the key to preventing graffiti. The coating composition is mainly SiOx, with a thickness greater than 100nm, like a strong and invisible shield. The hardness performance is excellent, with the Chinese pencil having a hardness of up to 9H and the Mitsubishi pencil having a hardness of 6H. Ordinary graffiti pigments and tools cannot damage it at all. Its transparency (visible light) is greater than 90%, and even after coating, the building can still display its original color and texture in sunlight. At the same time, the adhesion (grid cut method) reaches level 0, which means that the coating can firmly adhere to the surface of the building, and even after prolonged exposure to wind, rain, sun, and rain, it will not easily peel off.
During construction, the surface of the building should be cleaned first to remove impurities such as dust and oil, and then construction can be carried out through conventional methods such as spraying and wiping, which are simple and convenient to operate.
In summary, IOTA PHPS coating provides a long-lasting, aesthetically pleasing, and reliable solution for building anti graffiti. Whether it is commercial buildings, cultural venues, or residential buildings, all types of buildings can use it to avoid graffiti and maintain a clean and beautiful appearance for a long time.
