This is silicone sealant specially designed as secondary sealant for insulating glass, an essential raw material for IG production. It features excellent weather resistance, UV resistance and low water vapor transmission rate. It provides long‑lasting stable sealing, blocks moisture penetration and prevents fogging and condensation inside insulating glass units. It has strong adhesion to float glass, aluminum spacer and other substrates. With good elasticity, it accommodates thermal expansion and contraction, resists cracking and avoids air leakage for long‑term service. Widely used for insulating glass of building doors, windows and curtain walls.
