Hello, im struggling to get my head around the mix ratio for the eproxy resin. On the containers, it says 100 - 30, is this measured by weight, or quantity? 

Let's say I wanted to use a small amount of resin for example 5 KG in weight? How do I work out how much harder to use? 

I have made a mixture and it's been drying for 24 hours, however its still tacky, im assuming I have not used enough hardner?

Thanks for that information this has helped! 

My eproxy mixture has been at room temperature, however, heating has been off, so that can go down to 2 degrees! So I doubt the mixture is correct. It has been about 48 hours at least now. 

I will try another mixture and start again Smile They where only small 1CM by 0.5CM stickers anyway.

OK but what resin and what hardener speed were you using? - Also, an ambient temperature that could have gone down to 2'C would certainly stall the reaction - at this temperature the resin would stay uncured for months. If you're using the IN2 resin (for example) with a slow hardener then that would take more than 48hrs to cure at 15'C so it still might be OK, just in desperate need of some warm curing conditions.

Using your EL2 Laminating EProxy. The ambient temperature may not get that low to be honest, however today it was -2'C outside and the heating hasn't been on most of the day whilst we where all at work, so it would have been pretty cold. I will make another mixture and make some more but leave the ones I have made to one side see if they cure, I keep on touching one of them and it's still pretty tacky.
