Paint entropic forces

Entropic ordering also appears in nonbiological settings, especially in the ways polymer molecules clump together. For example, polymers added to. paint to improve the flow characteristics of the paint actually caused it to coagulate because of depletion forces. 

This unique behavior of an HMHEC can be exploited in applied-flow systems, such as latex paints. High molecular weight HECs tend to retain their elasticity even at high shear because of the entropic recoiling forces...
