  • Low-Density Potting Material
  • Self-Extinguishing Sealing Material
  • One-Hour Working Window

Product Description

EPOCAST® 1617 A/B is a two-component, low-density epoxy syntactic compound for edge sealing honeycomb structures. The mixed paste has a typical density of 0.70 g/cc and cures to an off-white, self-extinguishing material. A 100:20 resin-to-hardener mix ratio by weight and a typical 60–90 minute gel time for a 50 g mass at 25°C support manual preparation and placement. Cure options include seven days at 25°C or room-temperature gel followed by five hours at 52°C. Typical cured data include 6.9 MPa aluminum-to-aluminum lap shear and 37.9 MPa compressive strength at 25°C.

Key features

  • Low-density syntactic paste: The mixed system has a typical density of 0.70 g/cc for lightweight honeycomb edge sealing.
  • Practical processing window: Typical gel time is 60–90 minutes for a 50 g mass at 25°C.
  • Self-extinguishing cured material: Typical compressive strength is 5,500 psi at 25°C.

Applications / Suitable for

  • Edge sealing honeycomb structures.

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
