Big Dog Adhesives BD5405 NS Epoxy Adhesive

BD5405 NS is a two-part, non-sag, room temperature cure, epoxy adhesive designed for high speed bonding of metals, ceramics, and most plastics. It is a thixotropic paste consistency to prevent running and sagging it gives good resistance to water, salt spray, inorganic acids and bases, and most organic solvents. It is especially formulated for a 1:1 mix ratio for use in side by side cartridges, or to be used by hand mixing, or use with meter mix equipment. A handling cure is normally achieved at room temperature within 20 – 30 minutes with a full cure at room temperature within 24 hours. To accelerate the final cure, or to quicken the handling simply elevate the temperature.

Storage & Handling
  • Bring both components to room temperature prior to mixing. Mix 1 part A to 1 part B thoroughly for 30 to 60 seconds.
  • Dispense mixed material over properly positioned devices to be glued together. Do not pour more than 1/2” thick as the product may exotherm too high and may boil. As this is a very quick adhesive, you must work quickly to bond the pieces together.
  • Parts may be shipped within 24 hours but parts can be moved in 1 hour.
