| DOWSIL™ 734 Flowable Sealant (310 mL) – Clear Self-Leveling Silicone Sealant |
| Product Description |
| DOWSIL™ 734 is a low-viscosity, flowable silicone sealant designed to penetrate narrow spaces and complex geometries. It self-levels to provide a seamless barrier, curing at room temperature (RTV) to a clear, flexible rubber that protects against environmental factors. |
| Key Features |
| • Consistency: Clear, flowable, and self-leveling liquid • Application: Suitable for pouring, brushing, or automated dispensing • Curing: Room temperature vulcanizing (RTV) silicone • Resilience: Excellent resistance to UV, moisture, and extreme temperatures • Adhesion: Bonds well to glass, metal, plastics, and ceramics |
| Applications |
| • Potting and sealing of electronic boards and components • Insulation of hard-to-reach narrow gaps and joints • Sealing of lighting fixtures and glass housings • Gasket applications for HVAC and appliances |
| Advantages |
| • Flows easily into voids to ensure a 100% moisture-proof seal • Provides good dielectric properties for sensitive electrical circuits • Maintains flexibility over a wide temperature range without cracking • Convenient 310 mL cartridge for manual or pneumatic use |
