Hi Folks

Doesn't get much more unambiguous than that. 100 % Resin 30% Hardener

Haha... na man no worries, I always think about it twice as well... but yeah you're correct with 50g - 15g!

good luck.

If the EC-guys read this, 

The only problem with dispensing pumps they can some times give the wrong amount,they can be a pain if not using regular you have to prime them,using scales is much more precise.But I do understand the convenience of pumps.  

@Matthieu you can easily find cheap scales that are very precise (talking about 1/10th gr precision, sometimes even more), the thing is they can't weight more than 500gr. So perhaps using the scale you have now for larger quantities, and using the small scale for small quantities.
I used to do that. In any case the day I've been able to afford a pro scale things got so much easier.

Hi Philimon,

I'll take a look into whether we can make the labeling any more clear. I'm not aware of anyone else misinterpreting the labeling but I guess that doesn't mean it's never happened. I think we do also show some example mix ratios on that same bottle which I would have thought would confirm the mix ratio on the front?

Matthieu,

We have considered this, the primary reason against is accuracy but there are in fact several other reasons why these pump/volume based systems are not favoured. On the accuracy front it's impossible to properly have 'half' a pump or a 'quarter' of a pump so you end up rounding everything up, you do also need to prime the pumps which means wasting some usually and the pumps themselves leave the epoxy and hardener exposed to air (so they deteriorate faster and absorb moisture). Also, because you can't get exactly the right ratios needed in the pumps themselves (unless they're made specifically which is thousands in tooling costs) the resins need to be modified to be at the correct ratio for the pumps which might mean some compromise on the performance or behavior of the resin.

To get the accuracy you need on the scales it's worth having a couple of sets. The very accurate 'gram scales' which measure to 1/10th of a gram (0.1g) are great for tiny quantities and then for larger quantities a second set which measures to a 1g accuracy is fine.

All the best, Matt

thanks for your time and good information Matt, I didn't know there were so many "problems" with them!

Good news, my first mould is done and dusted! Many lessons learnt and i had a blast.
