H.B. Fuller MP5405

H.B. Fuller MP5405 is a two-part unfilled epoxy adhesive designed for ceramics and most plastics. It cures to a tough, semi-rigid material with a free-flowing viscosity. It has good resistance to water, salt spray, inorganic acids and bases, and most organic solvents. It was especially formulated to have a 1:1 mix ratio for use in either MMD equipment or side-by-side dual cartridges for easy dispensing. Handling strength is normally achieved at room temperature within 3 - 5 minutes, with full cure in 24 hours. An elevated temperature cure schedule can be used to reach final properties quickly.

General Instructions
  • Surfaces to be bonded must be clean, dry and free of other contaminants.
  • Bring both components to room temperature prior to mixing.
  • Measure out specified amounts of parts A and B and mix without introducing bubbles until homogenous.
  • Alternately use a static mixing nozzle. Apply to device allowing air to escape between and under components.
  • Allow to cure undisturbed until product is fully gelled or tack-free to the touch.
