Leather Surface Finishing
report_problem Problem Statement
Leather surface finishes rely heavily on polyurethane dispersions, nitrocellulose lacquers, and acrylic binders that contain VOCs and isocyanate-based crosslinkers. These finishes can release formaldehyde and contribute to indoor air quality problems in finished goods. A bio-based surface finish using naturally-derived compounds could provide equivalent abrasion resistance and aesthetics while eliminating hazardous crosslinker chemistry.
