I've HAD IT with this stuff. Every time I go to use it, i get a spill someplace or another. All of the spills so far have been outside, but someday I will probably stumble and get epoxy INSIDE the house.

The pumps on my bottles have a downward-pointing nozzle. This epoxy is US composites, which means it is really un-viscous (ok, I don't know any other words except for watery). Does anyoen have any suggestions on preventing drips? I am using a wooden-handled q-tip now to stop teh drips, but dangit this is not enough. Just doesn't pulg the nozzle.

If nobody has suggestions on how to stop this, i'm not using epoxy for a month or so. I am sick and tired of this, and had it up to here.

Use the plastic cap from bottle with a similar point. Look for ones from an old bottle of CA or even a tube of calk that might fit. I use aluminum foil around the areas where I work with epoxy. Have you tried wraping aluminum foil aroung the dispenser tip? You could even custom cast a cap for the dispenser using silicone bath tub calk.

could the pump be building up pressure in the can? try loosening the cap after using to vent the pressure, I'm just guessing

"To reduce exposure, use special gloves (nitrile rubber or nitrile butatoluene gloves) to protect the hands. Rubber gloves do not help as the resin penetrates through the glove in 30 seconds. Vinyl and neoprene rubber are not totally protective."

Is that part about rubber gloves right?

BN150 you are correct . . . most epoxy hardner and resin are of different densities so a strict 2:1 or 3:1 (whatever the volume proportion) weight proportion would not accurately measure the mixture.

You can devise a test sample to determine the exact weight proportion and use that factor. It is indeed simpler and definitely more accurate than volume measuring. I used some syringes to measure and weigh the test samples. I just use my triple beam balance to do the measuring at the calculated ratio.

The pumps are the easiest way to dispense the goo, but indeed the drips are problematic.

As far as corralling the drips, I keep my bottles in a medium-sized box with crumpled newspaper around them which keeps them upright and in place. I also have a little sleeve made from paper towels and tape that I slide over the pump spigots after use. Things get gooey, but at least they stay where I want them.

So THATS why I had that hardner left over once I was done with the resin...

Still hardens up pretty well, though... I guess ill just have to add a little more hardener next time...
