Anti-reflective coatings on plastic substrates
The anti-reflective (AR) coating formulated by Diamond Coatings is available for polycarbonate, acrylic and polyester film substrate for a variety of uses across many industries.
What is polycarbonate?
A tough plastic which comes in different grades, polycarbonate is 250x stronger than glass and provides chemical and physical durability. Its transparency makes it ideal for use in many applications, including optoelectronic devices, construction units such as greenhouses and security components, such as protective screens.
Classified as a thermoplastic, Polycarbonate offers heat, shock and humidity resistance and can be easily injection moulded and recycled. It is an electrical insulator and has flame-retardant properties.
When AR coatings are applied to polycarbonate, anti-glare and anti-reflective finishes can be added which helps to protect against fading and yellowing, caused by UV.
What is Optical Hard Coated Acrylic?
A harder substrate than polycarbonate but translucent like glass, optical hard coated acrylic is lighter than glass. Containing scratch resistant capabilities, Diamond Coating’s acrylic sheets are custom made and inspected to the highest optical standards.
The ITO plastic hard coating can be applied with anti-glare properties which shields it from the fading and yellowing caused by UV light, and has additional scratch resistant properties, it is 11x stronger on impact than standard float glass.
What is ITO Coated PET Film?
Polyester film (PET – polyethene terephthalate) is used within many applications for bearing properties such as high optical transmission and conductivity. They are also used in liquid crystal devices to realign the liquid crystal cells. They are common components for devices such as touchscreens, position sensors, electroluminescent lamps and shielding applications.
Utilised in industries like EMI shielding and telecommunications, the film mimics transmittance and resistance characteristics much like glass substrate.
When compared with polycarbonate and acrylic substrate, PET film exhibits durability at a wide temperature range and a high melting point, high optical transparency, low moisture absorption and high UV resistance.
A great choice for engineering and processing with metallisation and lamination, PET films are used for protective and hardcoat films; packaging and print film; security, tamper-evident and antimicrobial film.
Anti-reflective ITO PET film comes supplied with an optically clear adhesive and can be provided in sheet form, in continuous metre format on a roll or directly laminated onto your chosen substrate. Our AR1617 Film is a highly suitable and cost-effective solution for large display or digital signage applications.
The AR coating is conductive with a sheet resistance of typically 1000+ ohms/sq. The following anti reflective coating options are available from Diamond Coatings:
- DIAMOND-AR
Adaptable and can meet all forms of application. - DIAMOND-AR WET
Acrylic sheet with dipped AR coating giving approximate reflection of 3% - DIAMOND-AR VAC
Vacuum deposited AR at different wavelengths to suit customer requirements with average reflection of 0.8% - DIAMOND-AR COND
ITO conductive coating combined with multilayer AR
