Designed for convenient dispensing of WEST SYSTEM 207 and 209 Special Hardeners. The mini pumps mount directly on the resin and hardener containers and have been calibrated to deliver the correct working ratio of 3 parts by weight of resin to 1 part by weight of hardener with one stroke from each pump.

Dispense the correct proportions of resin and hardenerinto a clean plastic, metal or wax-free paper container. Do not use glass orfoam containers because of the potential hazard from exothermic heat build-up,and DO NOT attempt to adjust the cure time by altering the mix ratio. Anaccurate ratio is essential for a proper cure and full development of physicalproperties.
