IN2 Infusion Resin adding Acetone

Hi guys, I forgot to ask when I was on the phone about your opinions on adding acetone to IN2. 

The reason for this would be to create a cured resin that is a little less brittle and a lower modulus to give it better energy absorption to shock loading/ impacts. Your resin already has quite a low viscosity and so I was just wondering if there was any general advice or if you have had experience with this. I was considering some test specimens that have maybe 10-15% acetone by weight, or should I be looking at volume?

Any advice will be much appreciated.

Thanks,
Dave O.

Okay thanks for your advice Paul. Are there any other methods of getting a slightly less brittle epoxy. Any sort of plasticisers or impact modifiers? Any thing that will give it better energy absorption on impact, even a some sort of plasticiser that will cause the resin to plastically deform a little more before failiure.

Thanks,
