It really is true that SentryGlas\u00ae laminating SentryGlas is different when compared to standard PVB in many aspects. But if we first think of what SentryGlas\u00ae has been designed for, it is to give structural strength to the laminate to add highly increased safety and security performance<br \/>\nThe difference between SentryGlas\u00ae and standard PVB can be instantly seen \u2013 even when you&#8217;re comparing a piece of SentryGlas\u00ae and a piece of PVB at room temperature. SentryGlas\u00ae is a much stiffer material and also a bit more slippery material than PVB. And this can cause potential issues throughout the process that you need to consider when producing SentryGlas\u00ae laminates. So let&#8217;s look into them starting from the assembly room and moving to the heating, pre-pressing and autoclaving.<\/p>\n<p>First, let&#8217;s look into the assembly room and what kind of challenges SentryGlas\u00ae brings there to the table. First of all, since SentryGlas\u00ae is more slippery than normal PVB, to which people are mostly used to, it is more common to see the top glass sliding on the foil, especially with thin glass, than you would see with PVB. It means that it is really important to pay attention to having the glasses completely aligned and not to move the glass, for example, during the trimming process. Otherwise, it is quite typical to cause misalignment by slightly moving the top glass or pulling the edge of the SentryGlas\u00ae interlayer during the trimming.<br \/>\nThe second thing is that the trimming with SentryGlas\u00ae is a bit more difficult than with PVB. It is harder to make a straight cut through the material, and if you are trying to do that, it can cause an issue. That is why with SentryGlas\u00ae, you can just make a pre-cut, and then it is easier to tear off the remaining material away. Alternatively, it\u2019s also possible to order cut-to-size sheets which can allow avoid trimming completely.<\/p>\n<p>These were the main things to take into account in the assembly room. The second part is the heating process.<\/p>\n<p>While SentryGlas\u00ae is much stiffer in the room temperature than PVB, when you start heating it, it actually does get very soft very quickly. And even quicker than PVB does. This means that, compared to PVB, it is much easier to get the adhesion between SentryGlas\u00ae and the glass layer itself. This can lead to a situation of having trapped air in the trailing edge of the glass. The reason for this is that the trailing edge might have been overheated a bit and has closed before you were able to do de-airing. This, in turn, means that the operating window with SentryGlas\u00ae is narrower than with PVB which can be compensated for examply by lowering the heating temperature . So, it is very important to keep in mind that it is possible to run SentryGlas\u00ae with the same settings as PVB, but it might not be possible in certain areas of the PVB&#8217;s operating range, where higher temperatures still might be giving you the acceptable quality. When you are in the correct operating range in terms of furnace temperature and speed, you are able to run your production smoothly.<\/p>\n<p>The third part is the autoclave. This is what sometimes causes issues for the companies that already have an autoclave and have been used to laminate PVB. It is quite easy to imagine that you can just load the SentryGlas\u00ae laminates to the autoclave and have the same capacity as you have with PVB, but that\u2019s not always the case. The reason is that especially thick SentryGlas\u00ae laminates require a higher cooling rate during the glass processing cycle. So, if you are trying to process SentryGlas\u00ae with the same recipes and want to have the same amount of production as you have with PVB, way too often it not going to work. It is also important to take this into account when you are planning to purchase a new autoclave, so you could have it equipped with more cooling capability to achieve a decent capacity also with SentryGlas\u00ae.<\/p>\n<p>These three processing steps are the main things that make SentryGlas\u00ae lamination a bit more demanding than with PVB. And this is something you need to take into account in your production.<\/p>\n<p>It is also good to keep in mind that interlayers do evolve all the time. Therefore, it is good to discuss with the SentryGlas\u00ae interlayer manufacturer Kuraray (<a href=\"https:\/\/www.trosifol.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">www.trosifol.com<\/a>) what kind of recommendations they have. For example, SentryGlas\u00ae Xtra\u2122, which has been out for a while, should be much easier to process from the autoclave perspective than standard SentryGlas\u00ae . Kuraray is also providing specific lamination guides for SentryGlas\u00ae and SentryGlas\u00ae Xtra\u2122 for further information.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This week, we&#8217;re dealing with the following question: Why is SentryGlas\u00ae different to laminate than normal PVB?
