Ethylene glycol is newtonian or non newtonian fluid?

Some sources say it is treated as Newtonian as ethylene glycol has a higher viscosity than water, which affects the flow characteristics in simulations. But some also say it is non-Newtonian.

What’s wrong with a standard cyanoacrylate? No structural strength needed here, I think.

Dear Dr. Alan F Rawle

Thank you,

I need at least 30 minutes to work with it but I think cyanoacrylate hardened in that time!

Cyanoacrylate is instant. Then a 2-part epoxy if you want to 'fiddle'. Cure time can be varied with temperature.
