Neutral cure black fireproof silicone sealant designed for construction and transportation building applications. This high-performance sealant provides superior fire resistance and durability for critical infrastructure projects.

Our factory brings 20 years of specialized adhesive manufacturing experience across 40,000 square meters of production facilities. With highly mechanized equipment and over 200 production and R&D personnel, we maintain a daily output of 30,000 pieces while supporting OEM/ODM services with exceptional cost performance.

• Forms protective charred layer when exposed to fire, preventing flame penetration
• Maintains structural integrity under extreme temperatures up to 1000°C
• Delays fire spread and ensures fireproof partitions remain intact

• Emits minimal smoke and low levels of harmful gases (halogen-free options available)
• Complies with fire safety standards including UL 1479 and GB 23864

• Blocks heat transfer to protect adjacent structures from thermal damage
• Reduces noise transmission for enhanced soundproofing in fire-rated partitions

• Resists aging, moisture, and chemical corrosion for long-term performance
• Maintains elasticity and adhesion across extreme temperatures from -30°C to 120°C

Seals gaps around cables, pipes, and ducts penetrating fire-rated walls and floors in high-rise buildings. Prevents fire and smoke spread between compartments while maintaining fire resistance ratings up to 2-hour protection.

Used in power plants, petrochemical facilities, and boiler rooms to seal penetrations in high-risk zones. Withstands thermal shock and chemical corrosion in extreme environments from -30°C to 1000°C.

Seals ventilation ducts, cable trays, and emergency exits in metro tunnels, road tunnels, and airports. Meets smoke control regulations including EN 1366 for fireproofing in high-traffic enclosed spaces.

Protects IT infrastructure by sealing server room cable penetrations and UPS battery compartments. Complies with low-smoke, zero-halogen requirements per IEEE 1580 standards.
