Micronized wax exhibits excellent dispersibility and lubricity.

Function and mechanism in ink:
Anti-scratch and anti-abrasion: Wax particles are uniformly distributed
within the dried ink layer, with some protruding above the ink film surface
to form a fine, uneven protective layer. When external forces (such as
friction or scratching) act upon the ink layer, these protruding hard wax
particles first bear and disperse the pressure, thereby protecting the
relatively softer resin binder and significantly enhancing the ink layer's
resistance to abrasion.
Anti-Adhesion: The microscopic roughness created by wax particles on the ink
film surface reduces the actual contact area between layers during printed
material stacking or winding. This diminishes interfacial adhesion forces,
effectively preventing ‘smudging’ and ‘sticking’ on the reverse side of
printed items.
Enhanced Slip and Hand Feel: Surface wax particles impart a smooth tactile
sensation while reducing surface friction coefficients, greatly benefiting
subsequent processing operations such as die-cutting, box assembly, and
filling.
