I have spread some silicone on a glass piece and placed 4 different foils on it. I placed another thick glass on top and clamped down. Left it for 2 days.
From Left to Right below:
Window PVC Foil, Backing foil from PVC Foil, Flower cellophane foil and A3 blueprints protector sheets.
The A3 blueprints protector is quite thick. It cured on the sides but in the center it stayed a little wet after 2 days:
The Flower Cellophane foil was next and the silicone DID NOT dry at all. It stayed wet and sticky:
The PVC Foil Backing was next. I could not get it peeled off.The silicone was solidly stuck to the foil and glass:
Next was the PVC backing itself. It is textured on one side and absolutely smooth on the other:
IT WAS PERFECT! The silicone has dried underneath and was easy to peel off. The surface was smooth and as you will see perfectly transparent:
The PVC Foil looks like this:
It is used as a security foil or when you need to texture the glass on your windows. I have bought it from Mr Bricolage, but it is available in Praktiker or other stores. In the US you should be able to find something similar in Lowe's, Home Depot or Ace Hardware .
I will be coating the regular sized 150mm X 150mm glass with silicone next.
