Thread: Ready Steady Eddy
It does say low viscosity, but as you say is it really worth it? Does look like it'll fit the bill mind! I'm just drawing fences on my frame to see what volume I'll need...I've emailed them to see if it's equivalent to the Wests System!
Oh feck it....rush of blood to the head.....should have some winging it's way to me shortly. £33.36 inc P&P for 1.5kg of resin and 0.5kg of slow cure hardner. Will have a play and let you know how it pours. I reckon that I'll need 0.63 litres of mixed epoxy for 5mm depth so the standard pack should do nicely!
Now I feel responsible if it's shit so I'll have to order some as well
I was going to anyway, I like to live on the edge sometimes
Anyway just compared viscosity, West = 650 cps, Syntac 650-750 mPas, (1 cps = 1 mPas)
I'm thinking the main thing here with both of them is to get a good temperature going before pouring, it needs to be string vest only temperature minimum in the shed.

It's interesting you say you'll make it hot in the shed as I was just wondering whether it would be better to make the environment warmer or cooler. The mixture will certainly start of with a lower viscosity if it's warmer but it will also set faster as well (a rule of thumb from chemistry is a reaction will go twice as fast for every 10 deg C warmer) which means there is less time for it to find a level everywhere. I can't help feeling you'd be better off working with it as cold as you can to give it time to spread out before it sets. It says it'll cure down to 8 deg C if you are willing to accept a reduction in mechanical strength. Might be worth an experiment, make up a small amount cold and pour it onto a piece of scrap, see how far it spreads then repeat with a warm batch / environment.

I'll do mine in the test bay at work, there's one bay used for storage that's colder than the rest but still above 10°C I'd guess.

It's just that the West data sheet says this;
Minimum recommended temperature 70°F (21°C)
*Epoxy cures faster at higher temperatures and in thicker applications
and the Syntac data sheet quotes the viscosity at 25 deg.C

I think you should be careful re the temperature read the link to the wests system and it shows that it must not be cold, also I would check with your supply what the shrinkage and compression strength is of their product as there is not a lot of info on their data sheet. Don't forget to seal the inside of the trough because if you have any leaks it won't leave a level surface. Good luck. ..Clive
Well I'll be having the wood burner going anyway, it says the pot life is about 40 minutes so surely that's enough for it to settle ?
For making the trough I was thinking about using this, do you think the epoxy will eat into it ?

Edit: this is better, I'd missed the fact that previous stuff was only 1.75m long.
