Ultra‑Strong Weather‑Resistant Structural Silicone Sealant – High‑Strength, UV & Waterproof for Exterior Walls and Glass Curtain Walls
Feature
- Our one-part neutral-cure RTV silicone sealant offers efficient, stable curing.
- It is non-corrosive to all bonded substrates, safe for universal application.
- Boasting excellent resistance to UV, extreme heat and humidity, it delivers long-lasting durability in harsh conditions.
- Fully cured, it performs reliably across a wide temperature range of -50°C to 180°C.
- It accommodates up to 25% joint expansion and contraction, maintaining long-term structural integrity of assemblies.
Basic Uses
- This structural silicone sealant is specially designed for sealing and bonding high-rise building curtain walls, aluminum/terracotta cladding panels, and steel structures.
- It ensures reliable, secure structural mounting of various panel systems (e.g., glass, composite, metal cladding panels).
- It is also fully suitable for other structural curtain wall sealing applications in architectural and industrial projects.
