Hi,

after several tacky results with the resin that I've purchased, I'd like to ask you which resins you use? I've tried mixing the stuff for minutes and adding hardener way beyond the recommendation, but no help. Instead of fancy parts I get sticky fingers and a smelly room.

Timo,
I use Alumilite yellow, sets in 3 minutes and is very strong. The Alumilite white I find too soft for our type of use. I have tried some other brands which I found were too brittle and weak but I know these companies also had other products similar to Alumilite in hardness but not slower in setting time. So I stay with what I have. Works for me.

Sounds like your mixture is off or the resin is contaminated with moisture.

I use Polyester resins from a manufacturer here in Ontario, Ca. They ship all over and are very reasonable. My e-mail is [email protected] Send me an e-mail and I will get you the info.

It sounds like your mixture is off like was said before. Resin is very temperamental, you have to be pretty close. Also, you may have the wrong hardener which will produce the results you are getting. You want resin with a 3-4 minute pour time. You actually get about 2 min. as the material gets too thick to pour into molds. If moisture contaminates the resin, you get get what looks like crystals floating in the container and suspended in the fluid. Just run this through a pany hose strainer and the material is still k.

When the resin has passed its useful life, you will know because it will grow outside the molds and have alot of tiny air bubbles trapped in the castings.

Hi,

you were right, it seems I was using too much hardener. I thought that adding the amount of hardener would do the trick, but it was only making things worse. Thanks for the tips & info!

Yours, Timo
