ORMOCER^®s are inorganic-organic hybrid polymers synthesized by sol-gel processing. By finishing leather with relatively thin ORMOCER^® coating systems (<4 µm), excellent functional properties (Table) are achieved, as for instance:

• preservation of the natural optical and haptic properties
• pronounced hydrophobicity combined with high water vapor permeability and water vapor absorption
• low emissions
• excellent scratch resistance, fastness to rubbing and improved abrasion resistance
• sufficient heat resistance and light fastness

Moreover, ORMOCER^® finishings show an extraordinarily good and durable adhesion to leather.
