Where do you buy your Epoxy resin from

[CharlieRam]

Hi CharlieRam,

I guess west systems is proven route.

I was unable to get west systems tropical hardner so i looked for an alternative.
I found 3kg at 75 something euros
6 hrs pot life at 21 celsius.
About the same end strenght/hardness.



I found that the thicker the film was the harder it was to delaminate it from the steel.

I ended up pouring 5+mm thick 6 cm wide.

so a simple length x width x height will calculate volume.

I have a 185 cm x 100cm bed and ended up needing about 2.7 liter ~ 2.7kg.



i used 2m extra leveling channels.


so about 7.5 meters of 60mm wide 5+mm deep epoxy

I made an error during last pour and had to do it all over... so.. bought 6 kg in total.

Hope that helps.


4cm width 4mm thick is the minimum for 20mm rail as can be found on this forum.



Grtz Bert.

Thanks Bert

So it's 1kg to a litre? That's what I was thinking. So my channels are 40mm x 1350mm plus 2 channels to connect them at 40mm x 800mm. Say I go for a depth of 6mm epoxy that comes out at 1.032 litres.

Ideally I want to go for the wests but I can only seem to find the 209 in 1.45kg which is way too much. If it's 3.5:1 mix ratio then I should only need around 1kg of resin and 250g of hardener.
The 209 seems to be very unpopular in the UK though!

The System that we seem to use over here is the Wests System 105 / 209 http://www.westsystem.com/ss/use-guides/
it is a very slow curing hardener about 10 hours but you have to be careful with the temperature.

That link you posted doesn't seem to have the 209 either! The only place I've seen it listed only has the 1.45kg tin and I don't want to buy a big one as it's just a waste. I may have to price up importing it. I just don't understand why the 209 is so hard to get when all the others seem readily available.

Cheers Clive and Bert, Clive that was exactly what i was looking for :)
One more thing...... Can you check my calculations to make sure I'm right

2 rails 135cm x 4cm wide + 2 bridges @ 77.5cm x 4cm with depth of 6mm
(135+135+77.5+77.5)X4X0.6 = 1020cm3 = 1.02 Litres

1.02 Litres / 4 = 0.255 Litres 209 Hardener
@3:1 ratio by volume = 0.765 Litres of Resin.

Seems the weights are not quite 1 litre to 1 Kg as the manual states the ratio is 3.5:1 by weight.

Regards,

Charlie
