    Black Industrial Grade Silicone Sealant, 300 mL

    Part #: DYN-49297

    Dynatex 143403 is a black, one-component, industrial-grade RTV silicone sealant supplied in a 300 mL cartridge; it extrudes as a non-slumping paste and moisture-cures at room temperature to a tough, flexible, waterproof elastomer that bonds, seals, and insulates, with proven resistance to weathering, vibration, moisture, ozone, and temperature extremes. Fully cured, it is suitable for extended service up to 450 °F (232 °C) and brief exposure to 500 °F (260 °C).
