H.B. Fuller MP5405NS

H.B. Fuller MP5405NS is a two-part unfilled epoxy adhesive that is designed for high-speed bonding of metals, ceramics, and most plastics. It cures to a tough, semi-rigid material and has a thixotropic paste consistency to prevent running and sagging. This product has good resistance to water, salt spray, inorganic acids and bases, and most organic solvents. It was specially formulated to a 1:1 mix ratio for use in either MMD equipment or side-by-side dual cartridges for easy dispensing. A handling cure is normally achieved at room temperature within 20 - 30 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 stir (without introducing bubbles) until homogenous or use a static mixing nozzle.
  • Apply the uniform mixture to both surfaces.
  • Allow to cure while being held in place with light clamping.
