In demanding industrial and construction environments where moisture and fire pose constant threats, the Weatherproof Fireproof Silicone Sealant stands as a premium solution engineered to deliver uncompromising performance. This single-component, neutral-cure silicone sealant forms a durable, flexible barrier that resists water penetration, extreme temperatures, and flame spread, making it indispensable for critical sealing applications across diverse sectors. Its advanced formula combines weatherability and fire resistance without sacrificing adhesion or flexibility, ensuring long-term reliability in both indoor and outdoor settings.
Crafted from high-grade silicone elastomer, this sealant exhibits exceptional -80°F to 350°F (-62°C to 177°C) operating temperature range, maintaining flexibility even in extreme thermal cycles . The material achieves a 190 psi tensile strength and 350% elongation, providing superior resistance to mechanical stress and movement in dynamic applications . Its low VOC content (22 g/L) meets stringent environmental regulations while ensuring safe application in enclosed spaces.
Certified to UL 94 HB flammability standards, the sealant retards flame propagation and forms a protective char layer when exposed to high temperatures . Its UV-stable formulation resists ozone degradation, oxidation, and discoloration, maintaining performance even after prolonged outdoor exposure. The sealant cures to a mildew and mold-resistant finish, ideal for humid environments like commercial kitchens and wastewater facilities.
Featuring a 15-minute tack-free time and 24-hour full cure at ambient conditions, the sealant enables efficient installation schedules . It bonds effectively to concrete, metal, glass, plastic, and wood without requiring primers, reducing application complexity . The thixotropic paste consistency prevents sagging on vertical surfaces, ensuring clean, professional results in architectural and industrial sealing projects.

Ideal for sealing expansion joints in concrete facades, curtain walls, and precast panels where weather resistance is critical. Its fire-retardant properties make it suitable for fire-rated wall penetrations and HVAC ductwork installations in commercial buildings and hospitals.
Protects electrical enclosures, control cabinets, and machinery housings from water ingress and thermal cycling in manufacturing plants. The sealant's chemical resistance ensures reliable performance in chemical processing facilities and wastewater treatment plants.
Seals exterior components on railcars, buses, and marine vessels exposed to harsh weather conditions. Its saltwater resistance makes it valuable for dockside equipment, offshore platforms, and shipbuilding applications requiring long-term durability.
The sealant combines UV stability, ozone resistance, and waterproofing capabilities to withstand extreme weather conditions. Its formulation prevents cracking, shrinking, or hardening after years of sun, rain, and temperature fluctuations, maintaining a reliable seal in outdoor environments.
Yes, the sealant meets FDA 21 CFR 177.2600 standards, making it safe for incidental food contact applications . It is an excellent choice for sealing equipment in commercial kitchens, food processing plants, and beverage production facilities where hygiene and regulatory compliance are essential.
Unlike standard silicones, this product features a modified formulation that achieves UL 94 HB flame rating, demonstrating slower flame spread and self-extinguishing properties . While not classified as firestop material, it provides an extra layer of protection in applications where fire risk exists.
For optimal results, application should occur between -20°F to 122°F . In temperatures below 5°C, cure time may extend, and surfaces should be dry and free of frost. Using a primer on low-energy surfaces like plastics improves adhesion in cold conditions.
