Features Of Dow DOWSIL EI-2888 Non-Slump Silicone Sealant

  1. Non-slump formulation ensures zero sag and excellent shape retention on vertical and overhead surfaces.

  2. High-performance, acetoxy-cure silicone chemistry delivers rapid skin-over and robust adhesion to common substrates.

  3. Excellent resistance to weathering, UV exposure, and temperature extremes (–40 °C to +150 °C).

  4. Low modulus design accommodates dynamic joint movement without loss of seal integrity.

  5. Ready-to-use paste consistency eliminates need for mixing or priming on most non-porous surfaces.

Typical Applications Of Dow DOWSIL EI-2888 Non-Slump Silicone Sealant

  1. Sealing and bonding in architectural curtain wall systems and façade assemblies.

  2. Joint sealing for precast concrete panels and structural glazing perimeter details.

  3. Adhesive/sealant for metal cladding, aluminum composite panels (ACP), and stainless steel components.

  4. Non-structural bonding of glass, stone, and anodized aluminum in commercial building envelopes.

  5. Interior and exterior expansion joint treatment in high-rise and infrastructure projects.
