Material Notes:
Resinlab™ EP1238 is a two part acrylic / epoxy hybrid adhesive designed for bonding metals and plastics. It cures quickly at room temperature to a tough, semi-rigid material. It has good wetting to most surfaces and has controlled flow characteristics to give good wetting without excessive running or dripping. This product gives very good vibration and impact resistance. It gives good resistance to water, salt spray, inorganic acids and bases and most organic solvents. It was especially formulated to a 2A:1B volume mix ratio for use in side-by-side dispensing cartridges and meter/mix and dispense equipment. EP1238 will reach handle cure at room temperature within 6 – 12 hours. Cure time can be accelerated by the application of heat. Times and temperatures from 2 hours at 65°C to 30 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.Information Provided by Resinlab L.L.C., an Ellsworth Adhesives Company.
