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.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
