It provides exceptional adhesion to glass, aluminum, and other common facade materials, ensuring long-term architectural integrity under extreme environmental stress.

Benefits

Why Choose APEX Structural Adhesive

  • Enhanced Safety and Security

    Provides a robust barrier against forced entry and remains intact upon impact, preventing dangerous shards from falling.

  • High Load-Bearing Capacity

    Engineered to transfer dynamic wind loads and static weights from the glass to the building frame with a high safety factor.

  • Excellent Substrate Compatibility

    Formulated for primerless adhesion to anodized aluminum, powder-coated finishes, and high-performance coated glass.

  • Long-Term Waterproof Sealing

    Creates a permanent, flexible barrier that prevents air and water infiltration, enhancing the building's thermal efficiency.

Standard

Compliance and Material Options

Our structural adhesives meet international standards including ASTM C1184 and GB 16776, ensuring they meet the rigorous safety requirements for high-rise curtain wall applications.

Available in standard black, grey, and white finishes, with custom color matching available for large-scale projects to ensure seamless integration with the facade design.

FAQS

Frequently Asked Questions

Technical guidance on the application and performance of our structural silicone sealants

What is the difference between structural and weather sealant?
Structural sealant is designed to support the weight of the glass and resist wind loads, whereas weather sealant is primarily for waterproofing joints.
Can this adhesive be used on coated glass?
Yes, it is compatible with most high-performance coatings, though we recommend a compatibility test for specific low-E glass types.
What is the recommended application temperature
For optimal curing, the adhesive should be applied when substrate temperatures are between 5°C and 40°C.
Does it require a primer for aluminum frames?
In most cases, it offers primerless adhesion to clean aluminum, but site-specific adhesion testing is always recommended.
How long does the full curing process take?
While it skins over quickly, full structural strength is typically achieved within 7 to 14 days depending on humidity and temperature.
