Fireproof coatings have gained popularity due to the increased public awareness of fire safety. When purchasing fireproof coatings, it is crucial to focus on their quality and performance. However, many people are still unaware of the 15-cycle testing process that these coatings undergo. In this article, we will share some key information about fireproof coatings with you, brought to you by Wuhan Xinghai.
When applying fireproof coatings, they typically recover in a standard environment within 24 hours. These coatings offer good salt corrosion resistance, allowing for slight discoloration. They can be soaked for up to 7 days without significant damage. The coating remains strong, durable, and free from wrinkles, flaking, or foaming. While there may be a slight loss in light and heat resistance after 7 days of testing, the coating should not blister, peel, or lose its structural integrity. It should also withstand freeze-thaw cycles effectively.
Fire-retardant coatings can be used both outdoors and in damp environments, but in such conditions, it's necessary to apply a matching varnish for added protection. The product should be stored in metal drums or plastic containers and transported carefully. If stored in a ventilated area, it must be protected from direct sunlight, rain, and physical damage like drum damage, spillage, or leakage. The shelf life of the product is approximately six months.
Now, what exactly are the 15 cycles of fire retardant coatings? This is an important aspect to understand. The fireproof coating used in daily applications is tested through 15 cycles to ensure its durability. During these cycles, the coating should not foam, shed, or crack beyond a rating of 2. It should remain intact, not delaminate, and generally be applied in at least five layers. The thickness of the coating should be between 0.5 to 1 mm, with a typical application rate of about 1.5 kg per square meter. For insulated cables wrapped in oil paper, it's recommended to first wrap them with glass cloth before applying the coating.
Fireproof coatings are now widely used in everyday life, and more people are beginning to recognize the importance of fire prevention. Fireproof coatings are not only effective but also designed to meet strict performance standards, including the 15-cycle test. Understanding these specifications helps ensure proper application and long-term effectiveness.
