PERMABOND ET5147

Main features

  • 2 mm Structural Gap Filling
  • Extended 40-60 Minute Pot Life
  • FDA 175.105 Formulation

Product Description

Permabond ET5147 is a two-part, 2:1 epoxy adhesive for structural bonding of metal, wood, composites, and certain plastics. Its controlled-flow formulation fills gaps up to 2 mm, while a 40-60 minute pot life at 23 deg C provides assembly time before handling strength develops in 3-5 hours. Full cure is reached in 72 hours at 23 deg C or 1 hour at 60 deg C. Typical cured performance includes 18-20 N/mm2 shear strength on mild steel and 40-70 N/25 mm peel strength on aluminum. The formulation is made to meet FDA 175.105 requirements.

Key features

  • 2 mm Gap Fill: Fills structural bond gaps up to 2 mm.
  • Extended Pot Life: Provides 40-60 minutes of usable life at 23 deg C.
  • FDA 175.105 Formulation: Specifically formulated to meet FDA 175.105 requirements.

Applications

Applications include structural bonding of metal, wood, composites, and certain plastics where controlled flow, gap filling, and FDA 175.105 adhesive positioning are required.

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.
40-60 minutes
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.
1.3 / 1.2
Thermal Properties
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
50-60 °C
Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
15-25 kV/mm
