Features Of Dow DOWSIL SE 5400 Silicone Sealant

  1. High-performance, one-component, acetoxy-cure silicone sealant with rapid skin-over and deep-section cure.

  2. Excellent adhesion to common construction substrates including glass, aluminum, anodized metal, and painted surfaces—without primer.

  3. Superior resistance to UV radiation, ozone, and extreme temperature cycling (-40 °C to +150 °C).

  4. Low modulus formulation provides high elasticity and long-term joint movement capability (±25% movement accommodation).

  5. Non-corrosive to metals and compatible with most architectural glazing systems.

Typical Applications Of Dow DOWSIL SE 5400 Silicone Sealant

  1. Structural and perimeter sealing of insulating glass units (IGUs) in commercial façades.

  2. Weatherproofing of curtain wall and window frame assemblies.

  3. Sealing of aluminum composite panels (ACP) and metal cladding systems.

  4. Joint sealing in high-rise building envelope systems requiring durability and aesthetic consistency.

  5. Secondary sealing for solar photovoltaic mounting frames exposed to outdoor conditions.
