Evo Stik "Serious Glue" with polythene

[Zakko]

What happens if I use Evo Stik "Serious Glue" on polythene? The instructions say not to.

Does the polythene melt?

Does the glue refuse to bind to the polythene?

try it and report back ...

That would usually be the case. It's a type of superglue, and sometimes they produce considerable heat during the curing process ( depending on the material being glued ).

But I would have to wait 12 months to know that a slow reaction over 12 months would cause the polythene rod I want to stick to crumble and break up!

No glue sticks polythene. There are 2 ways to stick it

It's a strange superglue given how long it takes to even just hold something - let alone set fully. I've used it quite a bit and not noticed any heat. Not surprising given the time it takes to set.

Only thing I've found works on polythene is ordinary contact Evostick etc

- and not on a critical application.

[The Natural Philosopher]

same here. I did manage to sort of glue to nylon with car body filler but it was more a suction thing than a proper bond.

[Rod]

But any melting during setting would surely occur in much less time than that. Maybe 12 minutes at the outside?

If the instructions say not to - then I wouldn't expect it to work - I might try but only in the spirit of enquiry.

cheers, Pete.

It would show much faster than that

12 months is long enough for the sun's UV rays to depolymerise it

A few ideas here:

A friend used to work at a lab equipment suppliers and they made polythene lab aparatus by glueing bits and peices together. Unfortunately for us (as its nasty stuff) they used to etch the surface of the polythene with chromic acid before bonding with a "standard" (what ever that was) solvent based glue.
