Optical Coatings

Materials containing silicon and other metal atoms can be used in a wide range of optical applications.  Silicone gels and elastomers can be used as cladding or sealing materials with high optical transmission.  These materials can be adjusted to provide index matching of the substrate.  UV curable acrylate modified silicones can provide index matching for polymethacrylates while epoxy modified silicone systems can add scratch resistance to polycarbonates while.  If UV cure is not preferred, thermal cure can be used to cure silicone resins to surfaces to provide scratch resistance and weather resistance.  Metal organic compounds can be used in vapor depositions techniques to apply coatings on surfaces.  Silicones and silanes can be applied to optical fibers to provide lubricity, protection from moisture and help to reduce breakage and surface fractions.

Gelest, Inc. offers preformulated materials as well as the raw materials for these coatings.
