Main purpose


  1. Curtain Walls: Used to seal the gaps between glass panels and metal frames in curtain wall systems. This provides weatherproofing and structural integrity to the building envelope.

  2. Skylights: Used to seal the joints between glass or polycarbonate panels and metal or plastic frames to prevent water and air infiltration.

  3. Expansion Joints: Used in large buildings or structures to accommodate movement caused by factors like temperature changes, settling, and seismic activity.

  4. Structural Glazing: Used to bond glass or other building panels to a supporting frame, providing a secure and weather-resistant bond.


Product Feature


  • High Bond Strength:

    SJ-268 is designed to provide a strong and durable bond between various substrates, including glass, metal, concrete, and plastic. This high bond strength helps maintain the structural integrity of the bonded components.

  • Flexibility and Elasticity:

    It has excellent flexibility and elasticity, allowing them to accommodate movements caused by factors like thermal expansion and contraction, vibrations, and settling. This feature is particularly important in applications where dynamic stresses may occur.

  • Weather and UV Resistance:

    It is formulated to withstand exposure to harsh environmental conditions, including rain, sunlight, extreme temperatures, and UV radiation. This ensures that the sealant remains effective and maintains its integrity over time.

  • Chemical Resistance:

    It is resistant to a wide range of chemicals, including water, oils, solvents, and some cleaning agents. This makes them suitable for use in environments where exposure to different chemicals is expected.

  • Long-Term Durability:

    Excellent longevity and durability. When properly applied and cured, they can provide a reliable seal that lasts for many years, reducing the need for frequent maintenance or replacement.
