COOLTHERM E-105

Main features

  • Clear Unfilled Epoxy Resin
  • 600 cP Resin Viscosity
  • Multiple CoolTherm/Circalok Hardener Compatibility

Product Description

LORD® E-105 Clear Epoxy Resin is a general-purpose, unfilled liquid epoxy resin formulated for use with compatible CoolTherm™ and Circalok™ hardeners. Its clear appearance and typical viscosity of 600 cP at 25 °C support applications requiring high fluidity, including epoxy-fiberglass laminations, sealing, impregnating, and see-through castings. The selected hardener determines the mixed ratio, working life, cure schedule, mechanical characteristics, and electrical properties of the resulting two-component system. E-105 Clear has a typical specific gravity of 1.13 at 25 °C and a one-year shelf life when stored at 25 °C in its original, unopened container.

Key features

  • Clear, unfilled epoxy resin: Supports transparent castings and applications where the appearance of the encapsulated or impregnated assembly must remain visible.
  • High-fluidity processing: Provides a typical viscosity of 600 cP at 25 °C using an RVT viscometer with spindle No. 5 at 100 rpm.
  • Configurable epoxy system: Can be combined with compatible CoolTherm and Circalok hardeners to obtain different handling and cured-property profiles.

Applications / Suitable for

  • Epoxy-fiberglass laminations
  • Sealing and impregnating applications
  • See-through castings

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.

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
