Silicones are used to modify the brightness of the leather surface without repolishing. Of particular interest for automotive leather is a matt finish but at the same time abrasion resistance is required. It can be difficult to achieve the two features because often the properties that are important for abrasion resistance - wetting, spreading and lubrication - will normally give a very smooth flat surface which will have a high degree of gloss. Certain silicones however can be used to give a matt and abrasion resistant finish. The lubricating and wetting properties of silicones are believed to be key for achieving abrasion resistance. The outward orientating methyl groups will present a low energy surface. The best results are typically achieved with very high molecular weight silicones with possibly some degree of crosslinking. Functionality does not seem to be crucial. Also it is noted that there is a threshold concentration above which the performance will not improve further.
