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 features efficient and stable curing.
- Non-corrosive to all bonded substrates, it ensures safe and universal application.
- With excellent UV, high-temperature and humidity resistance, it provides long-lasting durability even under harsh conditions.
- When fully cured, it performs reliably within a wide temperature range of -50°C to 180°C.
- It allows for joint movement of up to 25% expansion and contraction, preserving the long-term structural integrity of assemblies.
Basic Uses
- This structural silicone sealant is specially designed for sealing and bonding curtain walls, aluminum/terracotta cladding panels and steel structures in high-rise buildings.
