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
