ASI® MP 54125 GR Epoxy Adhesive
Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: MP 54125GR is a two part, unfilled epoxy adhesive designed for bonding metals and plastics. It cures at room temperature to a tough, semi-rigid material. It has good wetting to most surfaces. This product gives very good vibration and impact resistance with high peel and shear strengths. It gives good resistance to water, salt spray, inorganic acids and bases and most organic solvents. It was formulated to a 1A:1B volume mix ratio for use in side-by-side dispensing cartridges and meter/mix and dispense equipment. MP 54125GR will reach full cure at room temperature within 24 –48 hours. Cure time can be accelerated by the application of heat. Times and temperatures from 2 hours at 65°C to 20 minutes at 100°C are typical for most applications. Time to heat substrate must be taken into account. Cooler temperatures will also extend work time and increase cure times.
