Start with the coating position and the required surface result—not with a resin name alone. This guide organizes the information needed for a more accurate first material screen.
Synthetic-leather projects can involve different substrates, coating structures and end-use requirements. A practical first screen should identify the substrate system, coat position, gloss or matte target, hand feel, durability tests and process conditions before a model is shortlisted.
| Project direction | Current candidate | Why it enters the first screen |
|---|---|---|
| Top coat with soft hand feel and durability requirements | RU-6720 | The current TDS identifies top-coat use and documents abrasion, hydrolysis, scratch, aging and yellowing resistance directions. |
| Matte surface with abrasion, scratch, cold and hydrolysis requirements | RU-6880 | The current TDS identifies a polycarbonate-based aliphatic matte PUD and lists these performance directions. |
| Clear film, extensibility, cold and flex requirements | RU-3340 | The current TDS documents clear film formation together with UV, cold and flex resistance and extensibility. |
This is preliminary screening logic, not a final formulation recommendation. Suitability must be validated in the customer’s actual substrate, formulation, process and test conditions.
Substrate, coat position, target gloss, hand feel, dry coating weight or film build where available, and processing temperature.
Required abrasion, scratch, hydrolysis, flex, cold, yellowing or other tests, including the customer’s test method and acceptance criteria.
No. Layer position, surface target and end-use test requirements can change the material screen substantially.
Yes. Matte appearance should be discussed together with hand feel, durability and process compatibility rather than as an isolated visual target.
No. A TDS supports initial screening. Final suitability still depends on the complete formulation, substrate, coating process and required test method.
Share the substrate, coat position, surface target, test standards and process conditions so FAST can continue the technical discussion.
