DOWSIL Q3-6679

Main features

  • Fuel- and Solvent-Resistant Insulation
  • Extended Working-Time Processing
  • Flexible Room-Temperature or Heat Cure

Product Description

FLUOROGEL Q3-6679 Dielectric Gel is a two-part clear fluorosilicone dielectric gel for protecting and insulating electronic assemblies exposed to fuels or solvents. The equal-part system uses a 1:1 mix ratio and offers a long working time for dispensing and assembly. It can cure at room temperature or with heat, allowing the cure approach to match the production schedule. The cured gel provides soft dielectric encapsulation while the fluorosilicone chemistry addresses applications that require solvent-resistant protection. Suitable uses include protective gel coverage in PCB system assemblies and dielectric insulation where fuel or solvent exposure is part of the operating environment.

Key features

  • Fuel and solvent resistance: Fluorosilicone gel construction is intended for dielectric protection where fuel or solvent exposure is required.
  • Equal-part mixing: A 1:1 mix ratio supports straightforward preparation of the two-part system.
  • Flexible cure options: Room-temperature or heat cure supports different assembly and production schedules.

Applications / Suitable for

  • Dielectric gel protection where fuel or solvent resistance is required
  • Protective gel coverage in PCB system assemblies

Two (Base | Catalyst)
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.

Electrical Properties
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
