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.

Thanks for the reply fellas.

Yer I,m looking at it as an option because for me it a $70 dollar difference in price for 5L for specific infusion resin. Nothing available

in my area so the cost to ship ( dangerous goods ) adds a fair bit to the cost.  A local fibreglass supplier here in Newcastle manufacture there own

epoxy , I talked with there chemist and it was his recommendation to do this as long as I use MEK and only 2%. I also have access to MEK being in the aircraft industry.




Yer I usually heat my epoxy and mould to at least 25 degrees before infusion.




My parts are not overly large so my concerned about flow might be unwarranted.
