Structural Silicone

ARBO structural silicone is typically used in glazing, curtain wall systems, and other construction applications where a strong, weather-resistant seal is essential. Below are some of the key points drawn from the specific ARBO products.If you can’t find the right sealant, get in touch with a member of our team and they can help you find the right sealant for you.

Perfect Gap for Strong Bonds

ARBO SST Structural Spacer Tape ensures an ideal gap between the insulated glass unit (IG) and frame, allowing the structural silicone to achieve a high-strength, primary bond essential for structurally glazed fabrications.

Short Term Support with Load-Bearing Durability  

The SST tape provides initial support to the IG unit during assembly, working seamlessly with ARBO structural silicone to deliver robust, load-bearing performance in the final installation.

Easy Application for Reliable Results
Surface Preparation: Clean, dry, and contaminant-free surfaces ensure optimal adhesion. Use Arbo cleaners, and primers, if necessary, for best results. Efficient Installation: Apply the tape directly to the frame, creating tight butt joints at corners. Press down with a seam roller for a secure initial bond. Precise Positioning: Position the IG unit carefully on the tape and apply pressure to strengthen the bond, preparing the surface for the structural silicone application.

High Performance in Any Condition

Flexible, Resilient Composition: Shore 00 hardness of 65-80 delivers the perfect balance of flexibility and support. Exceptional Tensile Strength: Over 1000 Kpa, providing enhanced durability during and post-assembly. Effective Thermal Resistance: Thermal conductivity of 0.052 W/mK maintains performance across a wide temperature range, from -30°C to +60°C.

Optimised Compatibility
ARBO SST is designed for seamless use with Arbo Ultraglaze Structural Silicone, enabling a cohesive, high-strength application ideal for architectural and glazing projects.

Long Lasting Quality 
Available in black for a clean look, ARBO SST has a storage life of up to 12 months when kept in dry conditions between +5°C and 25°C, ensuring reliability from project start to finish.

Many ARBO sealants comply with relevant British Standards (BS EN ISO 11600, BS 5889) and offer additional assurances for use in construction.
