Hello guys and girls

Has anyone had any practical experience thinning epoxy resin for infusion ?

I have been advised that if I use MEK at no more than 2% in the part A  it will be ok.

I understand that there may be a reduction in strength which wont be an issue for the parts I make.

I think it would work as is, depending on  the size and layup of your part. I regularly infuse with Araldite LY3600, which is a hand layup spec resin with a viscosity of 550cps. This infuses really well, I actually hugely prefer it to the Kinetix R118 infusion spec resin that I have used as well. 

What is the size of your part? I've used the LY3600 on parts as big as 3.5 sqm. This is about as big as I would go, at least without multiple feeds. It doesn't flow as fast as an infusion spec resin, so you want to be careful infusing without a flow mesh (say when using Soric or 3D PET core, these flow slower).
