常见问题 — 皮革整饰 化学品
How do silicone emulsions improve leather softness?
PDMS silicone emulsions penetrate the leather fiber structure during the fatliquoring stage, depositing a thin lubricating silicone film between collagen fiber bundles. This reduces fiber-fiber friction, resulting in a soft, smooth hand feel. The non-ionic emulsion system is compatible with standard anionic fatliquoring agents and does not interfere with dyestuff uptake.
What silicone products are used in leather surface finishing?
Amino silicone oils improve surface softness and smoothness in top coat finishing lacquers (0.5–3% addition). Epoxy-terminated silicone oils are used as reactive modifiers in PU-based top coats to improve flexibility and reduce cracking. Silicone waxes and PDMS emulsions are used in shoe care and leather dressing sprays for gloss and water repellency.
Can silicone additives be used in waterborne leather finishing systems?
Yes. Both PDMS emulsions and micro-emulsified amino silicone oils are water-based and directly compatible with waterborne PU and acrylic latex leather finishing systems. Add at 0.5–3% to the finishing lacquer with gentle stirring. High-shear mixing is not recommended as it can degrade emulsion stability.
