Micronized wax for leather processing

The core principle behind the use of micronized wax in leather processing is
that it migrates to the leather surface during the coating and film-forming
process, forming a micron-scale waxy protective layer. This reduces the
coefficient of friction, enhances abrasion and scratch resistance, improves
the hand feel, and boosts water-repellency and anti-adhesion properties.‌‌
Film Formation, Migration, and Surface Enrichment: During the drying or film-
forming stage of leather finishing agents, micronized wax migrates to the
surface due to differences in compatibility with the system, precipitating as
fine crystals to form a “wax-coated” surface layer.
‌Lubrication and Scratch Resistance‌: The low surface energy of wax
significantly reduces external contact friction, causing potential scratches
to slip away rather than penetrate, thereby improving scratch resistance,
abrasion resistance, and resistance to polishing.
‌Hand Feel Control‌: It provides a smooth, rich, or slightly velvety feel while
avoiding stickiness; certain waxes can also adjust the finish to a matte or
high-gloss effect.
