Getting the Most Out of Mini Pumps
Priming Mini Pumps
Priming the pumps before the first use is simple but important; the instructions in the package explain how to do this. You will also want to check the prime if the pump has been sitting for a long time, or when changing cans.
Storing Mini Pumps
That’s right, no need to buy new pumps every time you buy new cans of epoxy. Store the pumps right on the cans and when you run out of WEST SYSTEM Epoxy you can move your pumps to the new cans of resin and hardener.
Cleaning Mini Pumps
If the pumps have been sitting on the cans for a while they may develop a crust on the end of the spout. Hardener pumps particularly seem to do this. The crust is easily cleaned away: just break it off and wipe the spout. You can use warm water to clean the hardener pumps and acetone or denatured alcohol for the resin pump, if needed.
Dispensing with Mini Pumps
Use only full pump strokes and do not pull up on them; let them return on their own. Alternating one stroke of resin and one stroke of hardener eliminates the need to count strokes and reduces the time spent waiting for the pumps to return to the top of their stroke.
Temperature Variation & Dispensing
Slow pump return can be an issue when using epoxy in cooler weather when the epoxy becomes “thicker” (actually, more viscous as our chemists would say). Try to keep your resin and hardener warm even if what you’re working on isn’t. Mix your epoxy indoors if you’re working at low temperatures in the garage. In the boatyard, an empty cooler and a shop light with an incandescent 15-watt bulb will keep your resin and hardener nice and warm. Remember, warm epoxy will cure faster until it hits the cool/cold surface. Call and talk to one of our Technical Advisors about cold temperature bonding applications, check our User Manual & Product Guide, or see “Cold Weather Bonding” by technical advisor Don Gutzmer in Epoxyworks, issue 43.
Pumps with White Tops
Long-time WEST SYSTEM users may still have pumps with white tops (which we stopped selling back in 2002). The white-top pumps and the newer yellow-top pumps are not compatible and should not be combined. But as long as your old white-top pumps are still delivering resin and hardener on ratio (verified by a simple pot-life test), they’re good.
