Ahhhh.... there's nothing like the smell of PVA in the morning!

Unfortunately, I'm about to foul up the air with the smell of polyester resin. (mental note: need to buy another gallon of epoxy)

Argghhh.... my can of polyester resin is messed up! After manhandling the thing to unscrew the lid, I saw that the resin is all crystallized inside, with stalactites hanging down from the top. I'm not even going to attempt to use the remaining liquid inside.

Anybody know what causes this, and can it be avoided? The polyester resin was less than a year old, and the can has only been opened a few times.


Alright, I'm off the goody store to get some epoxy, and then work into the evening getting my fuse laid up.

Polyester resin can cure without the catalyst - through heat. The only thing the MEKP does is create heat.

Other factors may contribute to the curing of the resin - like contaminants.

Sometimes polyester that has crystalized is NOT cured, but rather has just changed form. It can be used when the crystalized stuff is dissolved in pure styrene monomer.

The only advantage of polyester is you can change the cure rate, it's cheap and there's no accurate measuring of components. Apart from that, it sucks.

I wondered why SEPD hadn't received any posts in the past few days. It's good to see that Scott revived the thread..

It smells like cr@p. It's sticky, greenish-purple and looks like alien goo. It can get so hot that it can ruin your project. There's no real way of controlling the horribly exothermic reaction. The catalyst will make you blind if it gets anywhere near your eyes. It's also a very good skin irritant.

Did I say it smells like cr@p? But it's cheap and easy, and that's why I still have half a gallon of it in my basement.

What a weird, foggy, wet, drippy morning. Perfect for reading RCG and sipping my coffee!

Bah. I'm stuck with my study group waiting for a study team member to finish up her part of the paper.

Thank God I have an internet connection!

I know that some people are ignorant. Can't be helped. Not everyone can know everything. But if I can admit that, why can't they?!?

People are still hopeful they're not - that's why.

*sigh* They have an expression for these people. "Always sure, but never right."

I got to work a short while ago, and realized I left my cell phone at home. I rarely get any calls at night, but I still feel naked without it.
