The growing demand for fireproof coatings stems from an increased public awareness of fire safety. When purchasing fireproof coatings, it is crucial to pay attention to their quality and performance. However, few people are familiar with the 15-cycle testing process that these coatings must undergo. Today, we’ll share some key information about fireproof coatings with you, brought to you by Wuhan Xinghai.
Fireproof coatings typically return to their normal state in a standard environment after 24 hours. They should resist salt corrosion, allow slight discoloration, and remain intact after being soaked for seven days. The coating should be strong, durable, and free from wrinkles, flaking, or foaming. While minor loss of light and heat resistance may occur, the coating should not blister, peel, or show significant damage after seven days of testing.
When used outdoors or in humid environments, fireproof coatings require a matching varnish to enhance their durability. These products should be stored in metal drums or plastic containers and transported carefully. In well-ventilated areas, they must be protected from sunlight, rain, and physical damage such as drum breakage or spills. The shelf life of the product is generally six months.
What exactly are the 15 cycles of fireproof coatings? This refers to a series of rigorous tests that ensure the coating’s performance under different conditions. After 15 cycles of testing, the coating should not bubble, crack, or shed. Cracks of up to 2 mm are acceptable, and the coating should not peel off or lose its integrity. Typically, the coating is applied at least five times, with a thickness ranging between 0.5 to 1 mm. The coverage is approximately 1.5 kg per square meter. For insulated cables wrapped in oil paper, it is recommended to first wrap them with glass cloth before applying the coating.
Fireproof coatings are widely used in everyday life, and more people are now recognizing the importance of fire prevention. These coatings are not only effective but also designed with specific performance standards, including the 15-cycle test. Understanding these details can help you make a better choice when selecting fireproof materials.
