Optical Coatings & Film

Hard Coating

Plastics optical components can be coated in poly-siloxane and acrylate based resin blends to impart more robust properties:

  • Glass-like look and feel
  • Dirt resistant, non-stick properties
  • Abrasion resistance to scuffs and scratches
  • Chemical resistance to harsh reagents and environments
  • Boiling water resistance for sterilisation processes and harsh environments
  • Anti-fog properties
  • Anti-microbial properties

In Mould Labelling (IML)

Abrasion resistant and chemical resistant outer layers can be applied to optical products by the In Mould Labelling (IML) process. A hard coated die-cut film component is located into the mould tool and when the polymer is injected into the tool, the film label is bonded to the outer surfaces of the finished moulded part.

The IML process enables optical functions to be applied onto the optical film label in its flat form, prior to in-moulding to the final product.

Optical Functions such as, anti-reflection, dichroic filters, mirror surfaces and heat reflection properties can be added.

Optical Coatings Film 1

Dip coating gives the widest flexibility in coating geometry and coating thickness control for thermally cured coatings, where as precision spray coating gives production automation advantages for UV cured resin systems.

Optical Coatings Film 2

In some cases, such as visors, it is useful to protect both inner and outer surfaces of the visor with the IML process and POL has developed tooling and process techniques to do this.

Vacuum Coating

Optical properties can also be applied by direct vacuum coating, including metal reflective layers, anti-reflection through to complex wavelength tuned dichroic multi-layers.
