DOW 734 Clear Flowable Silicone Sealant 300ml One Part RTV Elastomer for Industrial Sealing and Bonding Room Temperature Cure with Excellent Flow Adhesion and Flexibility

DOW 734 Flowable Silicone Sealant 300 ml Cartridge – Clear Color Available A one-component, solvent-free silicone elastomer formulated for a wide range of general-purpose sealing and bonding tasks. DOW 734 offers excellent flow and self-leveling characteristics, allowing it to easily penetrate narrow gaps and complex assemblies. It cures at room temperature upon exposure to atmospheric moisture, forming a durable and flexible rubber material. Available in clear or white color options. Applications Ideal for industrial sealing and bonding operations where a flowable compound is preferred. Excellent for sealing tight assemblies, cable entries, connectors, and other small gaps to ensure water resistance and environmental protection. Commonly used for maintenance or field repair work on equipment where previously cured silicone sections have been removed. Key Features and Advantages Single-part RTV system that cures at room temperature when exposed to moisture. Provides long-lasting flexibility and mechanical stability from –65 °C (–85 °F) up to +180 °C (+356 °F). Acetoxy cure chemistry; no solvent required. Self-leveling, easy to dispense, and provides smooth surface finishes. Fast tack-free time for improved handling efficiency. Strong adhesion to metals, glass, ceramics, and many plastics without primer. Excellent dielectric strength and electrical insulation. Complies with MIL-A-46106 performance standards.
