High-Performance Firestop Sealant for Large Gaps and Joints
FireSafe-FSS-C
FireSafe-FSS-C Firestop Sealant is a one-component neutral silicone fire sealant designed for excellent flexibility and strong adhesion. When exposed to fire, it forms a dense mesh structure that effectively blocks flames and heat transfer. With a displacement capacity ≥25%, it is ideal for sealing large gaps in floors and wall joints.
This firestop sealant dries quickly for easy application and provides reliable protection against water, smoke, and air leaks. It is safe, environmentally friendly, non-toxic, and resistant to staining. With over 40 years of durability, FireSafe-FSS-C offers a long-lasting solution for fireproof sealing in areas with large displacements.
Firestop Sealant Performance According to GB 14683-2003
For the FireSafe-FSS-C Firestop Sealant , we measured its performance in accordance with China’s national standard GB/T 14683-2003 for silicone construction sealants. This standard provides a comprehensive evaluation of the product’s ability to perform under construction conditions, particularly its displacement capacity. By adhering to this standard, we ensure that the sealant delivers consistent and reliable results in real-world applications.

Application of FireSafe-FSS-C
Superior Fire Resistance for Critical Sealing
In assembled buildings, a qualified and effective firestop system is crucial. In the event of a fire, a reliable fireproof sealing system can slow the spread of flames and reduce smoke concentration, giving people more time to escape and extinguish the fire. The fire resistance of joint sealants is critical to the overall performance of the firestop system. Sealants must not only be flame retardant and self-extinguishing, but also withstand high temperatures without ashing or breaking down. This ensures that the sealant continues to protect the integrity of building components during a fire.
FireSafe-FSS-C Gap Sealant offers exceptional fire resistance. Below, we provide key performance data for reference.

Instructions for use
Packaging and Storage
This product is packaged in 300mL per tube, with 20 tubes per carton. Storage conditions should be maintained between 3-35°C.
Installation Instructions
- Clean the opening; ensure the joint surface is dry, dust-free, and grease-free.
- Fill the holes or gaps with mineral wool or other backing materials.
- Apply the product at the specified thickness over the backing material.
- Smooth the surface using appropriate tools.
- If necessary, install identification stickers next to the fireproof sealing area for easy identification during future maintenance.
Recommendations for Use
- Use mineral wool (non-combustible) as the backing material, with a recommended density of over 100kg/m³.
