I just had @ 3/4 of a gallon jug - which was flowing fine a few days earlier - get an angular band of hardness… I got it just over three years ago - I called the distributor who suggested a hot water bath, and then a test batch.
Anyone out there have thoughts/suggestions?
I’ve had previous gallons for years before I finished one off, and have never had any issues like this.
I had the same issue with RR when my jug sat around for too long in the cabinet. I put the resin jug in the microwave, and zapped it for 20-30 seconds at a time until it was warm to the touch. Then I shook the jug really hard to get everything to mix together. After a few minues it returned to a nice smooth liquid state – just like new. I then glassed a board with it and it came out just fine.
Note: Don’t put the hardener in the microwave. I don’t know why, but I was told it’s bad to do that. Only the (blue) resin can go in the microwave.
Right on!
I’m pretty sure that’s what I’ve heard about the resin, but, like I wrote, it’s been so long, with no issues, that I’ve been kind of taken aback…
Common with any Epoxy if they sit thru a winter or two in a warehouse, cold storage or under the house. I have a slow cooker that I set the jug in and fill with water. Set the cooker on low and leave it for at least a couple of hours. Leave the cap on, but loosened. Allows for pressure release. Same thing can be done with a pot and a hot plate or electric stove. Warm it, don’t boil it. Worth a trip to Goodwill to find an old slow cooker. I have had whole jugs go solid and be brought back to life. I sell the stuff up here Oregon, so I have to keep an eye on my inventory. Since I know this trick works; I occasionally reliquify a few jugs every so often. PS Be careful with the microwave. You can smoke that stuff, ruin your microwave and start a fire. I like to microwave part A before I laminate, but liquefying a jug in microwave can be dangerous.
Thanks y’all!
The weird thig is - a few days ago it was all uniform and fine…
I put it in a bucket and ran hot water for a while, let set, repeat, repeat, looks good as new now! Whew…
I tend to lean on the “lazy side”. When my resin “whitens up” after being stored, I usually just set it out in the front yard in the sun for a few hours, then shake it up a little after its clear to remix. To be clear, I do this on the day before I’m actually going to use it so the resin isn’t too warm.
