Subject: Re: KR> epoxy "Air bubbles in the pumps can sometimes bias the mix ratio unless you check every batch."
I have been using West System for at least the last ten years and I have never experienced this. When you receive your epoxy and hardener, take it to your place of use and put it on the table or where ever you are going to dispense it from. Open the lid and remove the inner seal. Close the lid and put a few mixing sticks under the rear of the cans so that when you get to the bottom the pumps will still draw until you are just about empty. Let the cans sit overnight and come back the next day to insert the pumps. Don't move the cans just open them and insert the pumps. Pump each one in a separate container until you get a full pump without any air bubbles. That is it and you are now blessed with the easiest epoxy to use in my opinion. I don't check every single batch but approximately 90% of the time I will at least have a little left over in the bottom of my cup. I will lean the cup up against something and insert my mixing stick and come back the next day to remove the stick. Depending on how much I had left over it will either snap off the mixing stick or the residue will come out in one piece on the end of the stick. I have never had a problem with it setting up. If I had any complaints about this epoxy it would be the complete lack of styrene's! Stephen Teate Paradise, Texas ---------------- I concur. I've never had any issues with the West pumps. I also found them to be really handy with AeroPoxy, although the ratio was a bit different and should be weighed the first few times until you get the ratio down right. Whenever I mix epoxy, I always leave the cup and mixing sticks, brushes, etc to check for cure quality. A number of years ago I was building drones for a few years, so went through many gallons of these resins with very few issues. -Jeff Scott Los Alamos, NM _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
