When we ride in a car, airbags are a lifeline in critical moments; when construction workers wear protective suits, the coating on their clothing is the first line of defense against risks; when we use mobile phones, computers, and other 3C products, precise sealing designs are an invisible armor ensuring the stable operation of the equipment. Behind these scenarios closely related to safety, protection, and stability lies a key material—liquid silicone rubber with a special coating for airbags. Seemingly inconspicuous, it plays a crucial role silently in multiple fields thanks to its unique properties.
Some may wonder why this type of silicone rubber has become a favorite in so many applications. This stems from its core characteristics designed for practical needs. First, in products like airbags and protective clothing, the adhesion between the coating and the substrate is paramount. The substrate commonly used in these products is nylon 66, and the liquid silicone rubber specifically designed for airbag coatings exhibits excellent self-adhesion to nylon 66, firmly adhering to the substrate surface and resisting detachment even after repeated stretching and compression.It's important to understand that in the instant of a car collision, airbags need to deploy quickly and the coating needs to remain intact to effectively cushion the impact; if the coating of protective clothing peels off, it will lose its protective effect. This strong adhesion is the foundation for ensuring safety.
Secondly, from a production application perspective, its "low viscosity" characteristic is extremely advantageous. In large-scale factory production, materials need to be compatible with automated equipment—low-viscosity liquid silicone rubber can be easily fed automatically by pumps, eliminating the need for repeated manual stirring and conveying. This reduces labor costs and avoids errors caused by manual operation, making the production process smoother. At the same time, it also addresses the seemingly contradictory requirements of "rapid thermosetting" and "long operating time": it can quickly cure and mold after heating, significantly shortening the production cycle and improving efficiency.The longer processing time after mixing provides workers with room for adjustment and calibration, preventing product defects caused by rushing, and truly achieving a "win-win situation for both efficiency and quality."
Even more noteworthy is its superior mechanical properties, which extend its applications far beyond the airbag field. In the construction industry, the coatings of architectural textiles need to withstand wind, sun, and rain erosion; this silicone rubber can form a stable protective layer, extending the lifespan of textiles. In the 3C product sector, it can fill gaps in equipment, providing waterproof, dustproof, and anti-aging sealing to ensure the stable operation of electronic components. Even in protective clothing with extremely high protection requirements, its strong adhesion and durability can create a solid safety barrier for users.
