<p>I have been reading up on <a href="https://en.wikipedia.org/wiki/Cyanoacrylate" rel="nofollow noreferrer">cyanoacrylate</a>, commonly sold in the US as "Krazy Glue" or "Super Glue", because I want to to use it to repair small plastic parts on either toys or appliances, due to its strong hold and quick setting time. </p>

<p>However, I have heard that these types of glues will "melt" or otherwise dissolve certain types of plastics. My research on whether or not this is an actual chemical reaction between the compounds has been inconclusive. I do not see anything listed under properties or uses on Wikipedia, nor do I see any specific mentions or warnings on the product page for <a href="http://www.krazyglue.com/faqs" rel="nofollow noreferrer">Krazy Glue</a>.</p>

<p>So plastic is no mentioned either way which leads me to the question:</p>

The reason the label says "don't use on Teflon" is because *nothing* sticks to Teflon.
