HRI Coating

Ultimet Films offer High Refractive Index (HRI) Coating services for customers wishing to deposit coatings such as Zinc Sulfide (Zns) onto a range of films. HRI coatings such as ZnS are generally used to coat holographic films for security applications where transparency along with a high reflective appearance is required to enhance the hologram appearance but with the ability to be able to see images such as photographs, which sit underneath the hologram.

Customers can benefit from a quick turnaround service whereby free issue film is contract coated at widths as narrow as 200mm on our 1000mm vacuum coating machine which runs specialty products and coatings.
