Features Of DOW Corning 737 Silicone Sealant

  1. High-performance, one-component, moisture-curing silicone sealant with excellent adhesion to glass, aluminum, anodized metals, and painted surfaces.

  2. Outstanding resistance to weathering, UV radiation, ozone, and extreme temperatures (–40 °C to +200 °C continuous service).

  3. Low modulus formulation provides superior joint movement capability (±25% joint movement accommodation).

  4. Non-corrosive to sensitive substrates including copper, brass, and galvanized steel — suitable for architectural and electronic assemblies.

  5. Meets ASTM C920 Type S, Grade NS, Class 25, Use T, M, O, G, and A; passes UL 94 HB flammability rating.

Typical Applications Of DOW Corning 737 Silicone Sealant

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

  2. Sealing curtain wall systems, spandrel panels, and aluminum composite material (ACM) cladding joints.

  3. Weatherproofing of skylights, atriums, and architectural metal roof transitions.

  4. Electronic enclosure sealing where low outgassing and non-corrosive chemistry are critical.

  5. General-purpose bonding and sealing in transportation applications including railcar and bus body assembly.
