Polyester works with catalyst and hardener, but epoxy works only with hardeners. But there is slow and fast epoxy resin. Search on the web will give you more answers.
Hardener is a non scientific name for catalyst. It catalyzes cross-link between molecules of liquid resin so it become solid. You can speed up the crosslinking reaction with heat. Every extra 10 degrees C increase speed of reaction for 2-4 times. There are slow and fast hardener (catalyst) for epoxy (not the resin itself). Fast has higher concentration of acid and slow may have some inhibitors. If you do not know the kind of hardener you have the best way is to mix different ratios and test the result. Start with 1 part of hardener for 5 parts of epoxy and iterate to 1:1 - common range of mixing.
Your zest for the pursuit of a good time is contagious. Thank you Rob!
Thanks for sharing, it've been inspired me!
I'm waiting for new videos not only because of DIY. Soundtrack rocks!! Have discovered nice bands here :)
All your work is brilliant mate, keep experimenting, keep playing, love to see more of this kind of stuff! :D
Thank you, very interesting video. I wish you have a lot of money
respect
Hi Rob, I need some tips in the epoxy mix, what's the suggested ratio of resin and catalyst?
