In the field of fire protection, the performance of coating materials directly determines the safety level of protective products. A room-temperature vulcanizing silicone material specially developed for high-strength fire-resistant cloth, with its core advantages of high strength and high adhesion, has become a key choice to improve the safety performance of fire-resistant cloth, providing more reliable protection for various scenarios.
The most notable feature of this material is its excellent physical properties. The white protective layer formed after curing has moderate hardness, reaching the standard of Shore A 50—it neither becomes brittle due to excessive hardness nor loses support due to being too soft. Test data shows that its tensile strength can reach 5.5MPa, equivalent to bearing 55 kilograms of pull per square centimeter, and it maintains structural stability even in high-temperature environments. A 250% elongation rate endows it with excellent flexibility, allowing it to stretch with the deformation of the cloth and avoid rigid cracking; a tear strength of 16KN/m ensures it does not easily break in emergencies, building a solid line of defense for safety protection.
Construction convenience is an important guarantee for improving production efficiency. The material has excellent thixotropy, like a "cooperative coating"—during construction, it can easily adhere to the surface of glass fiber cloth through scraping or dipping, evenly covering every fiber. When the operation stops, it quickly sets without flowing, significantly reducing material waste and rework costs. More importantly, it has extremely strong adhesion to glass fiber cloth, with no delamination or peeling after curing, significantly improving the qualification rate of fire-resistant cloth production.
The usage operation is simple and easy to learn, adopting an A/B two-component design with a 1:1 weight ratio, without the need for complex measuring tools. Component A has a viscosity of 100,000mPa·s, and Component B has a viscosity of 80,000mPa·s. After mixing, the viscosity stabilizes at 85,500mPa·s, compatible with various coating equipment.
It should be noted that the material uses platinum catalytic technology, with the catalyst in Component A. During use, contact with impurities that may affect performance should be avoided; if coloring is required, colorants should be added and stirred evenly in Component B before mixing with Component A.
Storage conditions are lenient: unopened, it can be stored for 12 months at temperatures below 23°C, and the packaging label clearly marks the best use date. Even if it exceeds the shelf life, it can still be used after passing testing, reducing inventory pressure. In addition to fire-resistant cloth, it also plays a stable role in other scraping and dipping protective products.
