Define Polycarbonate glue...

Bump.

Bumping is Frowned upon around here, and just typically ends up bugging people, just FYI

Polycarbonate glue will be any glue marketed as such, a quick google search gives http://www.eplastics.com/Plastic/Lex...carbonate_Glue

If it isn't clearly marketed as polycarbonate glue I think you would have a hard time convincing your inspector.

Remember to take care when using these adhesives, the fumes are usually pretty powerful.

Well, what I mean also is, could we use Loctite to secure say... a magnet to a piece of aluminum? Or what in the rule book could we use for this.

[Brandtlamonte]

D'oh. I just thought of a magnet on the other side xD But yea what adhesives could we use even still that would work for these surfaces?

Seeing as you're asking about polycarbonate glue, I'm assuming that you're asking about the minibot.

So, what can be used to hold magnets to aluminum on the Minibot?

--Polycarbonate glue (anything sold as such, if I'm reading the trend of GDC answers on, "what constitutes an X" questions correctly)
--PVC cement (doubt that would really work, but it might be worth a shot)
--Loctite is not a glue; it's a threadlocker. You could try it... but don't expect success.
--Mechanical fasteners
--Electrical tape is specifically allowed by <R92-W>--no use specified.
--Hook and loop fastener might work, but then you've got two sides of hook and loop between the magnet and the plate.

I'd try the electrical tape. Nothing says it has to be used as an electrical insulator... (until the GDC notices this post, that is).

Loctite makes many amazing glues and epoxies. Loctite epoxy held our robot together last year.

Yep, but when the rule says "Loctite or similar threadlocking product", you're kind of limited to the threadlock versions. Might work, but might not.

Threadlocker is a thin, special purpose adhesive. An adhesive is a glue. IndySam is right. Let it go.

We want to use epoxy to glue a magnet to the aluminum on the minibot. Is epoxy an allowed polycarbonate glue?

If you want an official answer, Ask the GDC.

In light of their recent rulings, I would imagine their answer would be "A polycarbonate glue is anything that is marketed as a polycarbonate glue". But this is only an educated guess...

Close .. the GDC clarifies:

"Any glue that is marketed as specifically for bonding polycarbonate is allowed per R92-G. "

By the definition,

on amazon would work ... there are several glues in the paint section at the local Home Depot that say Acrylic, and I am going to go back and check, but I suspect that somewhere in the description of the Acrylic glues they also say also polycarbonate.
