Cleaning epoxy pumps

Post by graham mackay » Fri May 31, 2013 5:39 pm

Hi folks,

For those of you using pumps to dipense resin and hardener, what solvents do you use to periodically clean the pumps?

Thanks,

Graham

I weigh my epoxy on digital kitchen scale and skip the pumps. They failed me too many times.
scale makes using 2:1 epoxy simple.

I do not use 5:1 - but a simple spreadsheet could generate a list of mix ratios that would work.

Graham; Against what others might suggest, I use lacquer thinner for all clean up. I don't have any luck with vinegar...it takes too long and too much.

I've never needed to clean my hardener pump, and the only time I've needed to clean my resin pump was when it sat for a while and crystallized. For that I just ran it under hot water until it liquified again, and then pumped the goop out.

I'm with Bill. If they ever get to the point where they're really gummed up and not dispensing properly, I'll just buy new ones. They're cheap, and it's a lot less trouble than cleaning.
