Weatherproof & Structural Silicone Sealant
Series 1 — Neutral Silicone Sealant, Weatherproof Silicone Sealant and Structural Silicone Sealant for curtain walls, window and door applications. GB 16776 / GB/T 14683 certified.
Exterior-grade sealants engineered for curtain walls, window and door systems and structural glazing — where UV, monsoon rain and cyclic wind load decide whether a facade lasts 25 years or fails in two. Certified to GB 16776-2005 and GB/T 14683.
Weatherproof & Structural — Key Characteristics
Structural Load-Bearing Bonding
High-modulus neutral cure formulations that transfer dynamic wind load to the supporting substrate without micro-tearing.
Weather & UV Resistance
Tested against 85%+ relative humidity, 35°C+ ambient and continuous UV exposure with zero chalking or reversion.
Movement Accommodation
±25% to ±50% elastic recovery (Class 25 / Class 50) absorbs inter-storey drift and thermal expansion.
Certified Compliance
GB 16776-2005, GB/T 14683, ASTM C920 Type S — with third-party test reports and FORM E origin documents.
