    Smart Tint Vs Switchglass

    OK - I’m going to demonstrate why Smart Film is not an ideal situation.

    I have a piece of Smart Film here and what I’m going to do is I’m going to peel the liquid crystal film apart – I’ve already split it here, but as I’ve peeled it apart you can see where I’m pointing here, this is where the liquid crystal is supposed to be solid. What happens is because switchable film is very moisture-sensitive, you can see that as it’s come apart it’s actually started to come away from the plastic and this is not a good thing. So we can see that when I’ve peeled the switchable film apart from this corner you can see that the liquid crystal density has really come away to the point that it is clear. Now, this is an older piece that’s been exposed externally for approximately 12 months. What I’m going to show you now is a fresh piece of switchable film and this switchable film is brand new from production – it’s less than 2 weeks old. And I’m going to do the same thing – I’m going to basically split the film in half so that we can see the liquid crystals. As I pull this apart what we can see is that there’s great consistency in the liquid crystals. There are no liquid crystals that have come apart – they’re all very, very dense apart from where I have peeled it here – there is a little bit – but this is very, very dense. So I’ll put the two up next to each other.

    Now the switchable film once its laminated between 2 pieces of glass then it stops degrading because it is not exposed to the environment. But with switchable smart film, the smart film is external and it’s not protected and that’s why when the humidity gets to it this is what happens. So what we can see are the 2 different films – the one on the right is literally clear, there’s no liquid crystals when I peeled it apart because they’ve degraded over the last 12 months because it’s been external. Then I have a piece of Switch film to the left and the liquid crystals, even though I’ve torn them both apart down the middle – I’ve basically split them – so you can see the liquid crystals inside – the liquid crystal density is very, very good and what will happen is, for example, this piece of film once it is laminated it will stop degrading where the film - if I peel this completely apart – that’s 2 halves of a piece of switchable and you can see that the density is really, really good.

    For one last time let’s look at how bad this is. This is what happens when the film degrades – the liquid crystals start to basically come away and this affects performance. This is why we don’t recommend the Smart Tint.


    Smart Tint vs Switchglass – What is the difference?

    • Smart Tint is a film that can be retrofitted (stuck on) to the surface of your existing glass.
    • Switchglass is a ready-to-glaze product that incorporates a switchable Polymer-Dispersed Liquid Crystal film carefully laminated between two pieces of glass.

    There are many promotional videos on the internet showing Smart Tint being easily installed in just a few minutes. These videos clearly over-simplify the process. Handling switchable film (even in the form of Smart Tint) requires considerable skill and experience. If the film is creased, bent or bruised it will damage the liquid crystals inside leaving a clear patch where the damage occurs. Our technicians need a minimum of six months training in the handling, wiring and laying-up of switchable film for lamination and our clean room (a totally dust-free environment) is monitored to ensure quality handling is achieved and optimum standards are met at all times.

    It should be noted that a number of years ago, with the possibility of marketing these self-adhesive DIY switchable films ourselves, we tested a number of them (including Smart Tint), but based on the results all were rejected.
