Evaluate the complete formulation, not the resin alone
Synthetic Leather Water-Based PU Surface Coating
Water-based PU surface-coating selection for synthetic leather starts with the layer position, base construction, formulation compatibility, hand feel, drying and final resistance tests.

Common failure problems
- Poor film formation
- Tacky surface or blocking
- Hand feel outside target
- Compatibility loss
- Resistance below the buyer's test
Selection logic
Start with the use case, then narrow the route by substrate, process window and failure mode.

FAQ
Is PU-3526 a finished synthetic-leather topcoat?
No. It is a resin starting point. Final performance depends on the complete formulation, coating process and conditioning test.
