LOCTITE 3517

Main features

  • Low-Viscosity Dispense Flow
  • Extended Room-Temperature Pot Life
  • Dual Heat-Cure Scheduling

Product Description

LOCTITE ABLESTIK E 3517 is a one-part, black, graphite-filled epoxy sealant for applications requiring low electrical conductivity. Viscosity is 3,000 to 6,000 mPa s at 25 deg C, and the material has good dispense and flow behavior. A pot life of more than five days at 18 to 25 deg C supports an extended processing window. Heat-cure options are 2 hours at 120 deg C or 1 hour at 150 deg C. After cure at 150 deg C, volume resistivity is at most 3 x 10^4 ohm cm and tensile lap shear strength is more than 9 MPa.

Key features

  • Low-Viscosity Dispense Flow: Typical viscosity is 3,000 to 6,000 mPa s at 25 deg C with good dispense and flow behavior.
  • Extended Pot Life: Pot life is more than five days at 18 to 25 deg C.
  • Dual Heat-Cure Options: Guideline cure schedules are 2 hours at 120 deg C or 1 hour at 150 deg C.

Applications

Low-electrical-conductivity epoxy sealing applications.

Pot Life
Pot life is the amount of time it takes for the viscosity of a material to double (or quadruple for lower viscosity materials) in room temperature after a material is mixed. It is closely related to work life but it is not application dependent, less precise and more of a general indication of how fast a system is going to cure.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application

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.
