Surface Treatments
Does Restek offer custom Siltek® treatment?
We are always interested in your specific surface passivation needs. Surface deactivation of glass or metal with a Siltek® layer is available on a custom basis, and liner deactivation has become popular with some customers. Please keep in mind that treated surfaces must be able to withstand temperatures up to 400°C, as well as vacuum and pressure environments. It is important to remove any o-rings, seals, or other materials that will not withstand the treatment environment prior to sending items to Restek for coating.
