Description and Uses

Silicon 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
