S930 is a high-performance two-component neutral cure silicone sealant specially developed for insulating glass secondary sealing applications. It offers excellent adhesion, medium modulus, high strength and outstanding weather resistance. The neutral curing system ensures no corrosion to coated or Low-E glass, making it ideal for modern architectural glazing systems.

With fast and uniform curing after mixing, S930 provides excellent air-tightness, long-term durability and stable performance across a wide temperature range. It is compatible with most neutral silicone sealants and delivers reliable bonding to a wide variety of building materials.

Key Features & Benefits

• Two-component system: fast curing with uniform internal and external solidification

• Excellent air-tightness for insulating glass units
• Superior weathering resistance, ozone resistance and aging performance
• Wide temperature resistance: stable performance from -10°C to +100°C
• Solvent-free and environmentally safe
• Excellent adhesion to most building materials (primer recommended for special substrates)

Recommended Applications

• Secondary sealing for insulating glass units (IGU)
• Sealing and bonding for doors and windows

Mixing Ratio

• Component A (White) : Component B (Black)
• Mixing ratio: 10 : 1 (by volume)

Limitations

• Not suitable for structural glazing applications
