Product Overview
DOWSIL™ 730 FS Solvent Resistant Sealant is a one-component, fluorosilicone-based adhesive/sealant designed for demanding environments where resistance to fuels, oils, solvents, and extreme temperatures is critical. Engineered to cure at room temperature when exposed to atmospheric moisture, it forms a tough, flexible rubber that maintains performance across a broad temperature range (-65°C to 260°C). Key attributes include:
Type: Single-component fluorosiliconeCure System: Moisture-cured acetoxyConsistency: Non-sag pasteColor: WhiteOperating Temperature: -65°C to 260°C (-85°F to 500°F)Adhesion: Bonds to metals, glass, and many plastics (excluding PTFE, PE, PP)Electrical Properties: High dielectric strength (372 V/mil) and volume resistivity (5.1×10¹³ Ω·cm)
Product Introduction
DOWSIL™ 730 FS is a solvent-resistant silicone sealant formulated to address challenges in industries exposed to harsh chemicals and thermal stress. Its unique fluorosilicone chemistry ensures exceptional resistance to swelling, degradation, or embrittlement when in contact with fuels (e.g., JP-8, diesel), oils, and organic solvents. The formulation eliminates sagging or runoff during application, making it ideal for vertical or overhead use. Once cured, it retains flexibility and resilience, even under prolonged exposure to vibration, shock, or dynamic stress.
Specialized Attributes
Beyond standard sealing capabilities, DOWSIL™ 730 FS offers:
Enhanced Chemical Resistance: Withstands prolonged immersion in fuels and solvents, as demonstrated in tests showing minimal swell (<3.6%) and hardness change (-5 Shore A points after 7-day immersion in JP-8).
Thermal Stability: Maintains mechanical integrity up to 260°C, with tensile strength retention exceeding 90% after 14 days at 400°F (204°C).
Low Outgassing: Meets NASA low-outgassing standards (ASTM E595), ensuring compatibility with sensitive electronics and aerospace applications.
Fast Curing: Achieves tack-free status in 14 minutes (at 23°C/50% RH), enabling rapid assembly workflows.
Application Scenarios
DOWSIL™ 730 FS is widely used in sectors requiring durable, chemically resistant seals: Fuel Systems: Sealing fuel tanks, lines, and connectors in automotive, aerospace, and marine applications. Industrial Equipment: Bonding gaskets in chemical compressors, pumps, and valves exposed to oils or aggressive fluids. Electronics: Insulating and protecting components in high-voltage or temperature-sensitive devices. Construction: Caulking joints in infrastructure exposed to deicing fluids, lubricants, or extreme weather. Maintenance & Repair: Temporary or permanent repairs on rubber linings, corroded surfaces, or worn seals.
