Beschreibung
Zusammenfassung:	The surfaces of nano silica particles are modified with siloxane substituents containing aldehyde functional groups providing particles which are readily incorporated into compositions, such as polymeric coating compositions, to improve scratch resistance, dirt pick-up resistance, anti-adhesion properties and while maintaining excellent film forming properties. Provided are the novel silica particles, a simple economic process for their preparation and dirt repellent coatings and polymeric molding compositions containing them.
