In leather processing, micronized wax primarily serves as a functional finishing additive, imparting core properties to the leather such as scratch resistance, abrasion resistance, anti-adhesion, a smooth feel, and controllable luster.
Scratch Resistance and Abrasion Resistance: Micropowder wax particles are dispersed in the finishing agent and concentrate on the surface after film formation, reducing the coefficient of friction. This causes external forces to produce slippage rather than scratches, significantly improving rub resistance and service life.
Anti-Sticking and Stain Resistance: Reduces adhesion between leather surfaces while forming a hydrophobic barrier, enhancing stain resistance.
Gloss Control: High-melting-point waxes enhance gloss and heat resistance; specific particle size distributions or polyamide waxes can achieve a matte or semi-matte finish.
