West System 303 Mini Pump Sets Special Ratio

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 hardener into a clean plastic, metal or wax-free paper container. Do not use glass or foam 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. An accurate ratio is essential for a proper cure and full development of physical properties.

WARNING:  Do Not Use 303 Mini Pumps with 205 Or 206 Hardeners
