Dow Corning 734 flowable sealant is a self-leveling, one-component silicone RTV material. Its low viscosity allows it to fill many crevices and voids in potting and sealing applications. Supplied ready-to-use in white or clear formulations, this material cures at room temperature to a tough, rubbery solid. It adheres to many common substrates, including metals, ceramics and various plastics. - Dow Corning 734 flowable sealant resists weathering, moisture, vibration, ozone and temperature extremes. In addition, it stays flexible from -65 to 177 °C (-85 to 350 °F), intermittent to 204 °C (400 °F).
