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.

Give it a go, I'm confident it would work. Just be aware of the flow rate, that will be the biggest issue. You want to be sure that your pot life is long enough for the infusion. I would expect a 1sqm centre fed part to take about 25 minutes to half an hour to fully infuse (depending on layup schedule, more reinforcement will take longer), so just be sure that your pot life will handle that. If not, mix it in batches.
