 Technology Profile

Title:

Bio-based Polyurethane Dispersion (PUD) for Sustainable Leather Finishing 
Value Proposition:

A third-generation, castor-oil-derived anionic polyurethane dispersion, developed as a solvent-free, eco-friendly finishing binder for leather applications. The technology delivers soft handle, excellent flexibility, strong adhesion, and durability while reducing dependence on petrochemical-based binders. 
Summary Application:

Compatible with conventional leather finishing auxiliaries.
Suitable for full grain & corrected grain leathers.
Advantages:
  • High Performance Finishing Binder
  • Soft, clear, tough film formation
  • Excellent flex & crease resistance
  • Very good fastness
  • Good wet rub, light, water & perspiration resistance
  • Superior adhesion
  • Process & Application Friendly
