When the Smart Film is switched on, is the glass completely transparent?

In the ON state (transparent) it has a haze of less than 5%.

When switched OFF, is the surface completely opaque?

In the OFF state (translucent) the switchable film and glass register 55% (+/-5%) total transmitted light.

At what voltage does it operate?

The Smart Film is powered at 60Vac/50 Hz. A new 45Vac/50Hz version is also available

What are the general features?

In the "technical library" section TECHNICAL SHEETS you can see the general and technical characteristics of the Innoptec Smart Film.

What are the maximum dimensions?

Innoptec mainly supplies films cut to size. There is no maximum length for PDLC film but requirements usually do not exceed 3500mm for cut-to-size PDLC film. The maximum width of switchable film for glass lamination is 1800mm (available on request up to 2000mm). The maximum width of the switchable film - in the self-adhesive format - is 1500mm (Available on request up to 1800mm). The grey version goes up to a maximum width of 1500mm for both versions (laminated/self-adhesive).

How is it installed?

The switchable film can be applied self-adhesive on existing glass or laminated with EVA between two panes for new projects. The self-adhesive type can also be applied on organic (acrylic) glass, drastically reducing the weight of the artefact, making it easy to use in fairs, exhibitions, showcases, etc.

Can I apply silicone?

Only use the silicones recommended on our technical data sheets. Otherwise, the guarantee cannot be applied. Unsuitable silicones may create delaminations on the edges of the switchable film.

Which transformers should be used?

We will advise which transformers to use depending on the square metres ordered and the customer's requirements.

How many transformers are needed?

It depends on how the customer wants to handle the glazing and the surface area of the switchable films.

Where are the electrical connections positioned?

There are different types for positioning the electrical contacts. These can vary according to the length of the electrical opaque film or according to the customer's requirements if this is possible. In general, it is advisable to place the electrical contacts on the top of the glass surfaces.

When you look at the PDLC electric opaque film from an angle while it is ON, is it less transparent?

In the ON state (transparent) it registers a haze, at an angle of 45° less than 15%.

What is the energy consumption?

One square metre consumes 3 to 5 watts.

When does the PDLC film consume electricity?

It consumes electricity only in the ON (transparent) state. Consumption in the OFF (translucent) state is zero.

What is the life expectancy?

Innoptec PDLC electrically opaque film has a life expectancy of ten years. We have had films in continuous on/off testing for over 15 years.

What maintenance is required?

PDLC electric matting film requires no maintenance other than checking electrical connections, power supplies and seals annually.

How should the glass or adhesive film be cleaned?

The adhesive film should be cleaned when dirty with only alcohol and a non-scratch cloth without rubbing aggressively. Laminated glass should be cleaned with a cloth dampened with water only without wetting it excessively.

Can the electrical matting film be cut into non-geometrical shapes?

Yes, it can be cut to any shape using .dwg files. Innoptec will check the feasibility of cutting and if so suggest where to position the electrical connections.

Can PDLC electrically opaque film have holes?

Yes. We can drill holes of any shape and size.

What are the acoustic properties?

It depends on the characteristics of the glass used in the lamination. You can download our acoustic insulation test at the following link.

Can it be used in bathrooms or wet areas?

The electrical quality of PDLC electric matting film is tested on 100% of the surface area and is not afraid of water or wet environments, but the electrical connections must be installed according to the regulations concerning electrical circuits in bathrooms and similar environments.

Can Innoptec PDLC electric matting film be supplied in alternative colours?

It can be supplied in milk white or grey.

Can it be used for outdoor applications?

We recommend using the 45Vac version for application on glass facing outwards as it is much more temperature and UV stable.

Can it be used in doors?

YES. It can be inserted in any type of glass door as we can create slots/holes for handles and frames. On some types of doors, other small precautions will be necessary to avoid delamination after installation.

Can electrical matting film be used as a high-definition screen?

YES. In its OFF (translucent) state, the smart glass becomes a perfect surface for rear projection. This functionality is particularly appreciated in offices or conference centres, in retail and in TV studios.

Can the film be laminated with other types of glass (tempered, double-glazed, bullet-proof)?

Yes, but at the discretion of the laminator after carrying out the necessary tests.

What guarantee is offered?

The PDLC electric opacifier film is guaranteed for two years, extendable to five years depending on the accuracy of the technical solutions and materials prescribed and adopted for the final installation. Innoptec also retains traceability of the product for more than ten years, which means that for any replacement, it is able to reproduce the product with the exact same characteristics as before.

Can I remove the switchable film if I get fed up with it?

It can only be removed if applied to the glass in a self-adhesive manner. If laminated into the glass, it can no longer be removed.
