Shear Thinning - Everyday Examples

Everyday Examples

Ketchup/tomato sauce and modern paints are examples of pseudoplastic materials. When shaken or squeezed out of a bottle, ketchup will thin and flow readily but will retain its shape on a burger or plate. When modern paints are applied the shear created by the brush or roller will allow them to thin and wet out the surface evenly. Once applied the paints regain their higher viscosity which avoids drips and runs.

Famous quotes containing the words everyday and/or examples:

    “... You could sit there with the stains on your shoes
    Of the fresh earth from your own baby’s grave
    And talk about your everyday concerns.
    You had stood the spade up against the wall
    Outside there in the entry, for I saw it.”
    Robert Frost (1874–1963)

    Histories are more full of examples of the fidelity of dogs than of friends.
    Alexander Pope (1688–1744)
