Big Dog Adhesives BD54190 Epoxy Adhesive

BD54190 is a two-part, mineral filled, room temperature cure, epoxy adhesive designed for the bonding of metals, ceramics, and many plastics. It cures at room temperature to a tough, semi-flexible material. It has good wetting to most surfaces and is free flowing to penetrate cavities and give good self-leveling and air release. Because it is a filled epoxy, it gives very good vibration and impact resistance. It gives good resistance to water, salt spray, inorganic acids and bases and most organic solvents. It was especially formulated to a 1 part a to 1 part b volume ratio mix for use in side by side cartridges and meter mix equipment. BD54190 can reach handling cure at room temperature within 16 to 20 hours, but it can be accelerated by the use of heat. Times and temperatures from 2 hours at 65°c to 20 minutes at 100°c are typical for many applications. The time to heat the substrate must also be taken into consideration. Cooler temperatures will also extend work time and cure time.

Storage & Handling
  • Bring both components to room temperature prior to mixing. Mix 1 part A to 1 part B by volume or weight thoroughly for 30 seconds minutes.
  • Dispense mixed material over properly positioned devices to be glued together. Pre-bleed side by side cartridges the first 3 inches. Allow system to be undisturbed until fixtured.
  • Parts may be shipped within 24 hours but parts can be moved in 10 hours.
