• High wear and abrasion resistance — supports heavy-use leather applications
• Moisture- and chemical-resistant film that outperforms traditional casein coatings

Refined Result
A resilient, well-formed, breathable finishing film that adds strength, adhesion and resistance to coatings while preserving the natural aesthetic and tactile properties of the leather.
Application Notes
Use as an additive in finishing or top-coat systems.
Mix thoroughly before application. Apply using standard spray or finishing equipment according to your coating workflow.
Allow proper curing time for best performance.
Always follow manufacturer instructions and test product suitability prior to full-scale use.
