The impact during the construction phase
During the construction of polysilazane coating, construction personnel directly come into contact with the coating material and its volatile organic solvents. If protective measures are not in place, it may pose a health hazard. For example, organic solvents that evaporate during the construction process, such as toluene and xylene (which may be present in some polysilazane coating diluents), may irritate the respiratory tract and cause discomfort symptoms such as coughing and wheezing when inhaled by the human body. Long term exposure may also have adverse effects on organ functions such as the liver and kidneys. In addition, if the skin comes into direct contact with uncured polysilazane coating materials, it may cause skin allergies, redness, and swelling, especially for some people with sensitive skin.
Therefore, during the construction process, it is required that construction personnel strictly wear protective equipment, including gas masks, protective gloves, work clothes, and goggles, while ensuring good ventilation in the construction site, minimizing the chance of inhaling harmful gases and skin contact with coating materials, and ensuring the physical health of construction personnel.

The impact during the usage phase
When the cured polysilazane coating is applied to the surface of objects such as ships, under normal circumstances, its stability is high and it will not easily release harmful substances that pose a threat to human health. However, if the coating is damaged or aged during use, causing the coating to decompose or peel off, and the human body comes into contact with the fragments of these damaged coatings or the small molecular substances released, there may be certain health risks, such as causing skin discomfort. But as long as regular maintenance and inspection are carried out, and damaged coatings are repaired in a timely manner, such potential risks can be effectively avoided.
Overall, under reasonable production, standardized construction, and normal use and maintenance, the impact of polysilazane coatings on the environment and human health can be controlled at a relatively low level. With the continuous improvement of environmental protection technology and safety measures, their environmental friendliness and protection of human health will be further enhanced.
