Designed for accurate and convenient measurement of West System 105 resin and 205 or 206 hardener. Mini pumps ensure precise dispensing of the resin/hardener mixture and eliminate the problems associated with manual measurement. The pumps attach directly to the resin and hardener containers and are calibrated to deliver the correct ratio of five parts by weight of resin to one part hardener by weight (5:1) with a single stroke of each pump. When the resin and hardener are in continuous use, the pumps can remain attached to the containers. A full pump of each pump dispenses approximately 25 grams of resin and approximately 5 grams of hardener.
