Structural Sealant is a self-priming and shelf stable structural silicone adhesive that cures to a tough elastomeric rubber

Structural Sealant is a self-priming and shelf stable structural silicone adhesive that cures to a tough elastomeric rubber. It has excellent bond strength, elongation at break and tensile strength and can resist extreme temperatures and weathering.

Structural sealant joints must have the strength to resist primary loads (out-of-pane stresses such as wind) and the flexibility to resist secondary loads (in-plane movements, for example differential thermal expansion of glass components). These joint characteristics drive a trade-off between the structural capacity of the joint and its cost.

Most failures of field installed SSG are related to poor workmanship, including inadequate sealant bite width and adhesion and insufficient movement capability. However, the choice of the proper product for a given application and the design and installation procedures can minimize these risks.

Weather Resistance

Structural Sealant is a high performance silicone sealant exhibiting excellent unprimed adhesion to most building substrates with movement capability. It is easy to use and provides high quality bonding. Its good weather resistance makes it ideal for sealing and bonding structural glazing systems for hurricane or impact rated windows.

Safety

Structural Sealants are formulated for safety and are generally considered safe to use and non-toxic when completely cured. However, care must be taken with airborne particles and decomposition products that may exhibit significant vapor pressures or remain on surfaces, as well as uncured components.

Structurally-glazed curtainwall projects can be subjected to many different loads, including wind load and seismic and cyclic loading. These stresses can generate high levels of movement, which can cause structural and weather seals to fail or rupture. 

Ease of Application

Structural sealant is a type of polymer sealant that can be used for component reinforcement, bonding, and sealing. It has high bonding strength and is designed to withstand a wide range of temperatures. It can be applied to a variety of materials, including glass and metals. Structural silicone is also available in a variety of colors and formulations to meet specific project needs.
