Interior Sealing and Fire Resistant Applications

The fi nish and integrity of a rail vehicle is crucial to its long-term durability. A robust, watertight seal protects the wiring looms, vital electronic equipment and other components housed below the fl oor and behind interior panels. Sika has developed a range of products specifically formulated to offer longterm solutions for permanent elastic seals. With their easy to use one-component formulation, Sikaflex polyurethane adhesives finish interior components with a high performance elastic seal. Sikaflex hybrid technology combines the performance of traditional Sikaflex polyurethane systems, but shows additional characteristics such as reduced substrate surface preparation. SikaFiresil can also provide a highly elastic flame retardant and UV resistant silicone sealing solution. In certain applications, it is essential that products show fire resistant characteristics and comply with both local and international railway standards. These standards specify the performance of adhesives and sealants in some of the most exacting environments in the world, both above and below ground. If required these standards can be achieved by specific joint geometries with the inclusion of certain Sika assembly adhesives. Sika has developed a range of easy-to-use products that have been tested to international standards for use in fire resistant applications that still maintain joint strength and durability.
