West System 301-5 A Pump Set

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.

The use of the west system pump sets gives you the convenience of a clean dispense and an accurate mix.  Prime the pumps as shown on the video (see video here)  please note that these pumps are ’calibrated’ which means one full pump of 105 to one full pump of 205/206 hardener will give you the automatic ratio of 5 to 1 required.
