What is a slip compound and why are they added to ink?

Slip compounds include waxes, silicone, and Teflon. Slip compounds improve the ink's rub resistance by lowering the dried ink film's coefficient of friction. Slip compounds interfere with adhesion of coatings and film laminates, which is why inks formulated to be used with coatings and film laminates contain little or no slip agents.
