“Abrasion resistant” is useful only when the test method, load / cycles and acceptance criterion are defined. Use this guide to organize a synthetic-leather coating brief before comparing waterborne PU grades.
A useful abrasion-resistance brief should include the test method, load or cycle count, abrasive medium, coat position, substrate and acceptance criterion. If scratch resistance is also required, list it separately because abrasion and scratch are not the same failure mode.
| Model | Documented direction | Initial screening use |
|---|---|---|
| RU-6720 | Current product data includes abrasion and scratch resistance together with hydrolysis, aging and yellowing resistance directions. | Topcoat-oriented discussions where soft hand feel and multiple durability requirements are considered together. |
| RU-6880 | Current product data includes abrasion and scratch resistance for a polycarbonate-based matte aliphatic PUD, together with cold and hydrolysis resistance directions. | Matte synthetic-leather projects where surface durability and process stability are part of the same brief. |
Crosslinker, pigments, matting systems, additives and blend ratios can change final abrasion and scratch performance.
Film build, drying / curing, substrate preparation and test conditioning also affect the finished coating result.
No. They can be related in a coating system, but they use different test methods and should be specified separately.
RU-6720 and RU-6880 both include abrasion resistance among their documented performance directions; each has a different product position and surface target.
No. Final performance must be validated in the customer’s full formulation, process and test method.
Include substrate, coat position, test method, load / cycles, surface target and any related scratch or hydrolysis requirements.
Abrasion performance must still be verified in the finished system, but current product data can be used to identify the first topcoat and matte families worth testing.
