I encountered the need to solvent bond Polycarbonate to itself for one of the projects we're currently working on. After speaking with several vendors and reading various snippets online, I discovered that Methylene Chloride is the solvent of choice for bonding polycarbonate. Great, right? Except not so great. This is why: the method of sterilization we've chosen for our product is EtO (and we can't change it for technical reasons), and apparently EtO sterilization does not react well to anything with chlorine in it. So, the chloride part of methylene chloride presents a challenge. After further digging, a technician at Masterbond recommended a chemical called Cyclohexanone (which, I confirmed, has no chlorine in it). I've got some on order and plan on doing a test this week. I'll fill you in on the results when I have them.
Moral of the story - methylene chloride is the solvent of choice for bonding polycarbonate to itself; however, if you'll be EtO sterilizing your parts, using methylene chloride won't work and you should consider an alternative, possibly cyclohexanone.
