Structural Silicone Sealant - Engineered for Seamless Sealing with Glass and Metal
Features
Convenient one-component, neutral-cure RTV silicone sealant for easy application.
Safe, non-corrosive formula that won’t damage or discolor bonded surfaces.
Built to withstand harsh outdoor conditions, with excellent UV, heat and humidity resistance.
Maintains stable performance in extreme temperatures from -50℃ to 180℃ (fully cured).
±25% movement capability, absorbing structural stress to prevent cracking and failure.
Applications
- Structural bonding and weathertight sealing for stone and granite exterior curtain walls.
- Structural adhesion between frames and glass in sunrooms and greenhouse enclosures.
- Structural reinforcement and sealing for building retrofits and existing curtain wall maintenance.
- Sealing solutions for exterior facades and glass enclosures in subway and light rail stations.
