Point Fixed Glass Sealant
Point Fixed Glass Sealant
Professional Silicone Sealant for Point-Supported Glazing, Spider Glass Facades & Architectural Glass Systems
Point Fixed Glass Sealant is a premium-quality, neutral curing silicone sealant specifically developed for point-supported glazing systems, spider glass façades, structural glass assemblies, curtain walls, skylights, canopies, and large-span architectural glass structures.
Modern glass façade systems are continuously exposed to wind pressure, thermal expansion and contraction, building movement, seismic loads, UV radiation, moisture, and severe weather conditions. Engineered with advanced silicone polymer technology, this sealant delivers outstanding adhesion, exceptional movement capability, and long-term weatherproof protection to ensure structural reliability throughout the building lifecycle.
Designed for demanding commercial and infrastructure projects, it provides durable bonding and sealing performance on glass, stainless steel, aluminum, galvanized steel, and other commonly used construction materials.

Key Performance Advantages
Exceptional Structural Movement Capability
Point-supported glazing systems experience continuous stress caused by wind loads, thermal expansion, structural settlement, and seismic movement. This sealant absorbs and redistributes stress effectively, helping maintain façade integrity and reducing the risk of seal failure.
Long-Term UV & Weather Resistance
The advanced silicone formulation resists UV degradation, chalking, cracking, and embrittlement. It maintains flexibility and adhesion even after years of outdoor exposure.
Wide Temperature Adaptability
Maintains reliable performance from -50°C to +150°C, making it suitable for projects in extremely cold, hot, coastal, and desert climates.
Excellent Adhesion to Multiple Substrates
Provides strong adhesion to:
- Tempered Glass
- Laminated Glass
- SGP Laminated Glass
- PVB Laminated Glass
- Stainless Steel Spider Fittings
- Aluminum Profiles
- Galvanized Steel
- Powder-Coated Metals
