Ultra-Strong Weather-Resistant Structural Silicone Sealant – High-Strength, UV & Water Proof, Specifically Designed for Exterior Wall & Exterior Wall Glass Curtain Wall Applications
Feature
- Our one-part RTV silicone sealant is formulated with a neutral cure system, enabling efficient and stable curing performance.
- It is safe for application on all bonding substrates, with no corrosive effect on the base materials whatsoever.
- The sealant boasts superior resistance to UV radiation, extreme heat, and humid environments, ensuring long-lasting durability in harsh conditions.
- Once fully cured, it maintains consistent reliability across a wide temperature spectrum of -50°C to 180°C.
- With the ability to accommodate up to 25% joint expansion and contraction movements, it effectively preserves long-term structural integrity of bonded assemblies.
Basic Uses
- This structural silicone sealant is specifically designed for sealing and bonding high-rise building curtain walls, aluminum/terracotta cladding panels, and steel structures.
- It enables reliable and secure structural mounting of diverse panel systems (e.g., glass panels, composite panels, metal cladding panels).
- Additionally, it is fully suitable for various other structural curtain wall sealing applications across architectural and industrial projects.
