| Résumé : |
For a leather to be classified as genuine, the finish thickness requirement must be under 0.15 mm or 150 pm. For many years, finishers have been able to meet this requirement relatively easily and the market has had clarity as to the definition of coated leathers (>0.15 mm) and genuine leather. A finish thickness of around 0.1-0.12 mm has been able to meet most of the heavy-duty requirements of modem automotive finishes. The mechanical requirements include :
- Finish flexibility
- Finish adhesion (thicker finishes struggle here)
- Finish rubfastness
- Finish abrasion and scuff resistance.
The finish must also cover the underlying leather surface for the aesthetic of colour modification effects as the crust colour may not be exactly the correct colour required. The colour may also not be uniformly even, and a surface coating will make it so.
The leather may also contain natural animal signatures that will be covered to give a smooth "unblemished" surface with the illusion that the leather was never marked in the first place. These are the main considerations that a finisher will have in designing their formulation and, up until recently, the standard automotive finish was able to achieve this. |
