Structural Silicone Sealant

Structural Silicone Sealant

Silicone Structural Sealant is a one-component, self-priming, neutral-cure adhesive specifically formulated for silicone structural glazing and exhibits excellent un-primed adhesion to most building substrates. It has excellent tensile strength and has good joint movement capability.


  • Structural glazing of glass on aluminium frames.
  • Adhesion of glass to any other metal.

Use Cases of Structural Silicone Sealant

● Joint Sealing:

Silicone structural sealants are frequently used to seal seams and gaps between building components such as windows, doors, and curtain walls. This helps to keep air and water from entering the building.

● Windproofing:

They are ideal for weatherproofing applications, guaranteeing that rain, wind, and temperature variations do not compromise the building's structure.

● Expansion Joints:

Silicone sealants are utilized in expansion joints in more giant constructions such as bridges and high-rise buildings to allow for movement while maintaining a watertight seal.

● Glass Bonding:

Silicone sealants are also utilized in architectural designs to connect and seal glass panels, such as glass facades or balustrades.

● Industrial Applications:

They are used in industrial settings to seal seams in metal constructions, giving both strength and durability.
