Does Loctite Blue really damage Lexan? Let’s find out!
I think we all agree that Lexan is strong stuff. However, let’s take a moment to show just how strong it is. Take a look at this image from this page on Lynxmotion.com. The caption for this image reads “Will it Break? No!”
Next to the image is this quote from Jim, our generous host:
Strong stuff indeed. I think we’d all agree that Jim is a credible witness for this subject matter, so let’s accept that Lexan can be bent with a great deal of force without breaking.
For the experiment, I took a piece of 1/8 inch thick black Lexan, 4.5 inches long by 1.5 inches wide, and applied a layer of Loctite Blue along the center. This lexan had been random-orbit sanded to give it the nice smooth scratch-resistant satin finish that is very popular. I then set the Lexan on a shelf.
After five days, I picked up the piece of Lexan and decided it was time to test it. At first I gave it just a little bend with not much force at all. I heard a cracking sound. Interesting.
I then applied more force, and … SNAP! The piece of Lexan broke in not one, but two places, and the center piece went flying across the room. Look out!
The putfile site scaled down the image, so you can’t see it that well, but there is a noticable crazing pattern (like you would see on glazed pottery) where the Loctite was applied. And in case you are thinking it, no, the random-orbit sanding does not create a pattern like this.
Loctite Blue damages Lexan.
