Anwendungen
VerwendenSilicon monoxide (SiO) is a commonly used material for a wide variety of applications with the emphasis on IR multilayer coatings and adhesion promotion. SiO sublimes and should preferably be evaporated from resistance heated boats. AREAS OF APPLICATION Multilayer coatings especially for the IR, but also the VIS range Adhesion promoter (VIS, NIR) Electronics: dielectric, insulating and protective layers Design: iridescent coatings, colored metallically reflecting coatings e.g. on sun glasses Web coating: barrier layers on polymer films
