H.B. Fuller MP54190

H.B. Fuller MP54190 is a two-part mineral-filled epoxy adhesive for bonding metals and plastics. It cures at room temperature to a semi-flexible material with good wetting properties for self-leveling and air release. It provides excellent vibration and impact resistance and good resistance to water, salt spray, inorganic acids and bases, and most organic solvents. With a 1:1 volume mix ratio, it's suitable for use with dispensing cartridges and metering, mixing, and dispensing equipment. At room temperature, the adhesive reaches a handle cure within 16–24 hours, but heat can accelerate curing, with typical times and temperatures ranging from 2 hours at 65°C to 20 minutes at 100°C. Work and cure times will increase at cooler temperatures.

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.
