👉 The Evans fluid, named after its discoverer Robert Evans, is a synthetic, non-Newtonian fluid that exhibits shear-thinning behavior, meaning its viscosity decreases with increasing shear rate. This unique property allows it to flow easily under stress, such as when poured or stirred, but regain its thickness when the stress is removed. This characteristic makes it useful in various industrial applications, including coatings, paints, and adhesives, where controlled flow and stability are essential. The fluid's composition typically includes polymers or other complex molecules that form temporary networks under stress, returning to a more fluid state once the stress is removed.
