Structural Silicone Sealant - Exterior Enclosure Sealing Of Large Public Facilities
Features
Our one-component, neutral-curing RTV silicone sealant is designed for hassle-free, mess-free application.
Formulated to be non-corrosive, it is safe for use with aluminum, glass, stone and other common building materials.
Engineered for long-term outdoor performance, it resists UV rays, heat and humidity to prevent degradation.
With a service temperature range of -50℃ to 180℃ (fully cured), it stays stable in the harshest climates.
Its ±25% movement capability allows it to flex with the building, preventing leaks and structural failure.
Applications
- Waterproof structural sealing for steel buildings and metal roof joints.
- Strong structural fixing and sealing for exterior aluminum veneer and honeycomb panels.
- Professional curtain wall solutions for airports, railway stations and exhibition centers.
- Precision secondary structural sealing for insulating glass units.
- Dependable sealing for exterior walls and glass enclosures in transit stations.
