H.B. Fuller MP54190GR

H.B. Fuller MP54190GR is a two-part adhesive that is easy to mix and cures at room temperature, making it suitable for bonding a variety of materials, including metals, glass, ceramics, and plastics. This medium-viscosity polyamide/epoxy adhesive is recommended for low-stress, high-impact, and high-peel strength bonding applications of dissimilar materials, offering superior thermal shock resistance, dimensional stability, and resistance to water, weather, and many chemicals. This adhesive system is designed for use in side-by-side dispensing cartridges and metering, mixing, and dispensing equipment with a recommended 1A:1B volume mix ratio. Handle cure time is typically 16–24 hours at room temperature, but this can be accelerated with heat. It's worth noting that cooler temperatures will increase work and cure times, and substrate heat-up time should be taken into account.

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.
