EPOCAST® 1614-A3 epoxy structural syntactic adhesive must be thawed and allowed to reach ambient temperature (70 °F – 80 °F) before use. Cartridges placed at ambient temperature will typically thaw in 2 to 4 hours, whereas patties may require 3 to 4 hours. Thawing may be accelerated by placing a frozen cartridge or patty in a 125 °F (52 °C) oven for one hour. For optimum performance, it is recommended that EPOCAST® 1614-A3 epoxy structural syntactic adhesive to be used in a dry environment below 60% R.H. High humidity or moisture may have a negative impact on cure and performance. To prevent moisture contamination, do not store uncapped cartridges and keep patty material tightly wrapped in plastic film. Never immerse patties in water.
Cure cycle
Cure cycle refers to the measured time and temperature of the material as determined by thermocouple. Typical cure schedules involve heating the material at a rate of 3–7°F (2 - 4 °C) from room temperature to 260 °F (127 °C) for 90 minutes, or to 350 °F (177 °C) for 60 minutes. Applications that desire minimal shrinkage may apply slower ramp rates.- Application Information
- EPOCAST® 1614-A3 epoxy structural syntactic adhesive is suitable for aerospace applications, which require high strength and low density, in the areas of honeycomb core reinforcement for structural bonding and joining, fastener or attachment potting and panel edge reinforcing, etc.
