Our fireproof and flame-retardant silicone sealant is really a top-tier sealing option—engineered first and foremost for serious fire resistance, but it doesn’t skimp on the basic sealing and sticking power you need either. We’ve used advanced silicone polymer tech plus specialized flame-retardant additives to make it, and it checks all the boxes for tough fire safety standards.When it’s hit with high heat or open flames, it does three key things: stops flames from spreading fast, cuts down on smoke, and forms a protective char layer that holds up.
What’s nice about it is how versatile it is, too. It sticks really well to all sorts of materials—concrete, metal, glass, ceramic, most plastics—and it won’t corrode or damage them at all. And it’s tough as nails against bad weather: extreme temps, UV rays, rain, even chemicals—none of that messes with its performance long-term. That means it works just as well outside as it does inside.
We see it used a lot in places where fire safety can’t be compromised: fire-rated joints, HVAC systems, electrical boxes, building exteriors, even industrial gear. It’s not just for sealing out air, water, or dust (though it does that great)—it’s a real fire barrier that boosts overall safety. Applying it is easy, too; it has a smooth consistency, and it cures at room temp. Once it’s set, it’s flexible enough to handle small movements in the material without cracking—super durable.
Oh, and it’s non-toxic with low odor, both while curing and after. Meets all the environmental and health rules, so whether it’s a home, office, or factory project, it’s a safe pick—especially when you can’t afford to skip on fire safety or good sealing.
Product selling points focus on
1. Reliable Fire-Rated Protection: Meets international fire safety standards (e.g., UL 1479, EN 1366-4) with certified fire resistance ratings (typically 30–120 minutes), forming an intumescent barrier that expands under heat to seal gaps and prevent flame, smoke, and toxic gas penetration.
2. Superior Silicone Durability: Retains the core benefits of high-performance silicone—excellent flexibility (up to 300% elongation), weather resistance (-40°C to 150°C), and UV stability—maintaining sealing integrity in indoor/outdoor environments without cracking, shrinking, or hardening over time.
3. Strong Multi-Substrate Adhesion: Bonds securely to glass, metal, concrete, masonry, and most plastics (with no primer needed for most applications), creating a permanent, airtight/watertight seal that enhances both fire protection and structural reliability.
4. Smoke & Toxic Gas Mitigation: Formulated to limit the release of toxic fumes during combustion and block smoke migration, improving occupant evacuation time and reducing health hazards in fire emergencies.
5. Versatile Sealing Applications: Ideal for fire-rated joints, curtain walls, door/window frames, ductwork, electrical penetrations, and industrial equipment—suitable for commercial buildings, industrial facilities, and residential spaces requiring fire-safe sealing.
6. Water & Chemical Resistance: Resists moisture, humidity, and common industrial chemicals, preventing water intrusion and corrosion while maintaining fire performance even in damp or harsh service conditions.
7. Easy Installation & Workability: Features a smooth, non-sagging consistency for precise application via standard caulking guns; cures quickly (tack-free in 15–30 minutes, full cure in 24 hours) to minimize project downtime and ensure efficient fireproofing.
8. Low Maintenance & Longevity: Engineered for long-term durability with no frequent reapplication required, resisting aging,mold, and mildew growth—providing consistent fire protection and sealing performance for decades.
