SILASTIC 5-8733

Main features

Fuel-Resistant Fluorosilicone Chemistry
One-Part Cartridge Application
190% Cured Elongation

Product Description

DOWSIL 5-8733 Fluorosilicone Sealant is a gray, one-part moisture-curing sealant for bonding, sealing, and caulking where resistance to documented fuels, solvents, and chemicals is required. The ready-to-use paste is supplied in a 225 g cartridge and has a typical specific gravity of 1.4. After cure, typical commercial properties include 46 Shore A hardness, 400 psi tensile strength, and 190% elongation. Its fluorosilicone chemistry supports aerospace, automotive, and industrial sealing evaluations involving jet fuel, gasoline, or solvent exposure, provided the exact substrate, fluid, concentration, temperature, duration, cure, and joint configuration are validated.

Key features

One-part cartridge application: Ready-to-use gray paste in a 225 g package
Fuel and solvent resistance: Supports sealing evaluations under documented chemical-exposure conditions
190% cured elongation: Typical commercial value for the cured fluorosilicone

Applications

Bonding, sealing, and caulking in aerospace, automotive, and industrial assemblies exposed to validated jet-fuel, gasoline, solvent, or chemical conditions.
