Fiberglass mixing

**theprojectpat** · 06-08-2006, 05:52 PM

As everyone knows, when mixing the harner in with the resin, there isn't much worktime..my question is what do you guys usually use to mix it in. I've tried to use glass cups and they will either crack or will just ruin the glass once it hardens. I've also tried platic cups and the resin eats through them. What works the best for you guys?

I go to 7-11 and grab a few coffee cups. They are paper cups with a waxy coating and hold up fine to the resin.

I use these http://www.cfsnet.co.uk/acatalog/CFS...ng_Cup_93.html
they can be re-used 6 times or so by cracking the resin out.

paint mixing cups at walmart - the plastic ones...

something like $0.60 a pop.

as V8 mentioned, they can be reused.

Styrofoam holds out long enough for 2 uses... I sometime wrap it in tape and get to use it for a day or so.

I'm not so sure I'd want the styrofoam that's deteroriated to be mixed in to my project....

I usually use the walmart paint cups as mentioned above. They have ounce marks on the side which is good for mixing. Sometimes I wrap them with aluminum foil if I intend to reuse them.

yea the 1x10^-8 m^3 of styro in my resin creates real problems

Most commercially available fiberglass resin is polystyrene. That's the same stuff styrofoam is made out of and shouldn't see ill effects if some made its way into the project.

You mean you guys actually measure out the resin and hardener? Amateurs....
