The Role Of Water-based Wax Dispersion In The Leather Industry

2024-06-30   Pageview:28

The role of water-based wax slurry in the leather industry, leather wax powder, is a modified powder of a certain fineness, with the characteristics of stress discoloration, scorching, wear resistance, and improved feel, and is increasingly used in the leather industry.

Leather water-based wax is an odorless, non-toxic, non-corrosive white emulsion. It has excellent acid and alkali resistance. The wax slurry has good transparency and does not affect leveling. The wax slurry is mainly used in solvent-based wood paint, plastic paint, printing ink, varnish, etc.

1. When different wax slurries are used for leather top coating, some can increase the gloss or brightness of the leather, and some can produce a matte effect to present the charm of genuine leather.

2. Secondly, the water-based wax that produces a bright effect has a very small particle size requirement and a relatively simple composition. It forms a uniform and continuous wax film on the surface of the leather. The film is very smooth at the microscopic level and has a strong reflection effect on light waves, thus having a glossy feel.
3. The water-based wax particles that produce the matting effect are relatively large, forming a non-homogeneous and microscopically uneven surface on the leather surface, which produces a strong scattering effect on light waves. The scattering effect is the fundamental reason why the matting agent produces the matting effect.

Adding water-based wax slurry to leather finishing agents mainly plays the role of filling the coating, improving the feel of the coating, wear resistance, anti-sticking and increasing gloss. From the perspective of use, it can be divided into soft wax and hard wax, which are used for the bottom layer, middle layer and top layer of leather respectively; from the ionic properties of the emulsion, it can be divided into non-ionic, anionic and cationic wax emulsions, which can be used in combination with finishing agents with different ionic properties.
