Pealing Vinyl

Can anyone give me an explanation for why this vinyl is pealing. We installed this on the front glass of this building with etched windows. We used 3m ij 40C with 3m 8510 laminate. This building does get a lot of direct sun.

We’ve wrapped these same windows in the past with no problem.

Should we have used IJ180?

are window washers using somethingbwith a silicone additive?
like all the new paints, to increase "washability" ?

IJ40-c is removable. I think that's the issue. I would probably have used IJ35-C. It looks like a smooth flat surface, so you wouldn't need a cast vinyl.

It needs to be removable. It’s a temporary installation for a museum.

Two things.

1. The more opaque glass is, the more energy is deposited in the glass. Etched glass will heat up considerably more than transparent or clear glass.

2. I do not recommend using calandered vinyl for most outdoor applications. Big flat sheets may give you a few years service, but individually cut letters and shapes have internal tensions as a result of the manufacturing process. The coefficient of the energy in heated glass in combination with the latent energy inherent in calendered vinyl will cause these results and other undesirable effects. In addition, IJ 40c is designed to be repositionable and easy to remove. It would make sense that the failure would be at the adhesive interface.

IJ 40c is a great product when used appropriately. A cast, solid color vinyl would have been the best choice. A cast, printed and laminated vinyl with a matching cast laminate would be a distant second choice (only if a satisfactory solid cast vinyl color could not be selected).

Thanks for your response. What would you recommend for a full coverage wrap on these windows? The same client wants to wrap all the windows in a clear vinyl to produce a stained glass look. Would ij180 clear with 8518 laminate work well?

3M IJ180 will stick to the glass. Personally, I can't afford to take the risk of installing a full coverage wrap on a window, let alone an etched one which has its structural integrity already compromised. Also take into consideration that removing it will be risky as well. I'd walk.

Would you walk because it’s an etched window or because it’s glass? Full window wraps are everywhere. It’s not an uncommon application?

I was just in vagus for printing United and all of the casinos had some sort of wrap on their windows.

Basically, something is attacking that from the top, either through gravity or man-made, but something is falling down on it. Can't be snow or ice, so it could be something dripping off the roof when it rains if no one has touched it since you installed it. Whatever..... it has nothing to do with the vinyl you used.

I've had a few large windows crack. High quality thick plate glass is less of an issue, but regular window glass can have internal tensions; depending on how it is installed, sometimes just tapping it or leaning against it can cause it to crack. Heat and cold (especially the differential) can cause internal stress. Etched glass is more fragile than regular glass (just think of how they cut glass: a light score on one surface and it easily snaps into pieces!

You used a 7 year Calendared vinyl in a full sun application with a 4 year calendared laminate. Both were not good choices for durability and for the effects of the full sun. I believe what you are seeing here is the extra energy from the sun causing the calendared vinyl to try to return to a ball shape (it is what calendared vinyl does over time) and the air channels in the vinyl make for a little less adhesive holding it back - and then we have the laminate on top which is less engineered for this much sunlight, thus adding more to the energy trying to curl starting at the edges. A good example of why 3M has reduced warranty in full sun applications.

IJ180 with 8520 laminate would have been the better choice.
