Aqueous coating composition to provide the surface of an object with a durable hydrophilic coating, medical device for introduction into a human or animal body, object having anti-fogging properties, and object having increased x-ray and radar visibility combined with lubricity properties. and anti-fog '

摘要

A coating composition is disclosed which comprises an aqueous polymeric matrix, a hydrophilic polymer, a colloidal metal oxide and a crosslinker. The coating composition when applied on medical devices is hydrophilic, shows improved lubricity, abrasion resistance and substrate adhesion on metallic or plastic substrates. The coating also shows improved water sheeting thus providing the coated substrates with anti-fog properties. The coating absorbs aqueous dye or stain solutions making the substrate suitable for printing.
