The requirements for the performance of 2-pack polyurethane clear coatings are increasing constantly: In many high performance applications the use of nanosized silica particles is an answer to these demands.2-pack polyurethane coatings can be formulated by using polyols with various chain length and oh-values and different isocyanate crosslinker to create different mechanical properties.by adding nanosilica composites coating properties like scratch and abrasion resistance can be improved dramatically. A correlation between nanosized silica particles and the content was found without any influence to gloss and transparency.new coating systems can be developed by incorporating nanosilica technology into traditional binders for 2-pack polyurethane coatings. This is a reliable solution to formulate resistant and clear coatings.
