Another glue (solvent cement) question

Ya can never have enough chemicals, I say. But enough is enough, so I am posing this question, which I copied and pasted from my "Not a door" post, which not many may see.

Anyway, I have been experimenting with various solvent cements. That wasn't my intention (I have work to do), but when I tried a new (to me) one compared with what I had been using, I thought, "Dang, I like that stuff!" Then I tried my trusty old MEK and found that for certain things--like attaching my mullions to the window frames--it worked real good too. Then I saw a MLS post where somebody swore by Testors (the kind in the little squeezy bottle that looks like a miniature oil can). And there's the liquid stuff in a little can I got from Russ at TAP. Suffice to say, my mind is boggled. Or is it the methylethylketone or the trichloromethane talking? /DesktopModules/NTForums/themes/mls/emoticons/crazy.gif

BTW, we're talking about styrene, acrylic, and other plastics. Not wood, so don't tell me about Eileen's Tacky Glue or Elmer's Yellow or whatever. We live in termite country, so no wood. Besides, if I gotta destroy the environment, I'd rather save a tree, even if I'm contributing to pollution by using petroleum-based products and related chemicals, which may also be destroying the ozone layer. /DesktopModules/NTForums/themes/mls/emoticons/tongue.gif

BTW Part II: Do ya know what Trichloromethane is? Ether! No wonder I was feeling so mellow as I worked on my store project. /DesktopModules/NTForums/themes/mls/emoticons/hehe.gif

Joe,
The largest component of Acrylic Solvent Cement is Methylene Chloride (dichloromethane). Here is a link to our MSDS for TAP Acrylic Cement. TAP Acrylic Cement is Weld-On #3 packaged with our label on it. This allows us to sell the product at a Lower Cost. If you look at the
MSDS for Weld-On #16 you will see that it has an added ingredient...MEK. The MEK seems to help it bond to the styrene better. At TAP we also use MEK to bond ABS.....

And to clarify the bonding to the Polycarbonate (Marklon)material ... Since the Polycarbonate is so strong and difficult to break, the Glue Joints will tend to fail when put under stress before the plastic itself breaks. This is the case no matter what you use to glue it. My experience has been that the Acrylic Cement gives the strongest joint when bonding polycarbonate. The Marklon is NOT the same as the Acetal or Nylon that some of the Trucks are made from, nor is it the same material that the ties are manufactured from.
