Proper epoxy curing and full development of its physical properties requires a precise ratio of resin and hardener. The WEST SYSTEM 300 Mini Pump Set makes it easy to dispense the proper ratio, while eliminating the hassle of measuring by weight or volume. These calibrated mini pumps deliver the correct working ratio with one full pump stroke each of resin and hardener. They mount directly on the containers and can be left installed during storage.
