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.
