Hi! I'm Rafa, a spanish student of industrial engineer and I'm going to do my proyect in order to finish my career. I need a non-newtonian fluid which has next characteristics:

It has to be transparent.

It has to work a low shear rate (0.003-0.5) s^-1 having a medium-low viscosity (no more than 70 Pa·s more less).

I don't know if it will be difficult to be find it, but I need the fluid as soon as possible.

Any information, it will be great for me! Thanks so much

I believe some shampoos are behave in a non-newtonian way and are transparent to an extent

However most common non-newtonian fluids behave in that manner because of the presence of long chain molecules within suspension which would also scatter light and render the fluid opaque

Uncured silicone rubbers might work. Some of them are fairly transparent. They exhibit marked flow thinning at high shear rates.

Here's a link to some folks at Cape Cod Research that may interest you. I don't know if they've been able to develop this product, or whether it's available outside the US military, but there is a business contact that will know more. Good luck.
