Gluing resin to styrene???

[Mike77]

I know super glue can be used on resin, and of course standard model glue is fine for styrene, but what's best to use when mating resin parts to styrene parts? My hunch is to use super glue but I know it doesn't grab styrene like model glue does. Any help is appreciated.

You need to use superglue. CA glue. I use zap-a-gap green label

I USE CA GLUE & 5 MIN EPOXY

As stated, superglue or 5 min epoxy. Styrene glue depends on "melting" the two pieces together. Resin doesn't melt so styrene glue will not hold. Superglue or epoxy hold things together with a mechanical bond which is what is needed for your application.

+1 on superglue or epoxy. If the part won't be subjected to stress, superglue will do fine. If it will, epoxy is better. If you're going to need to sand/blend the resin and styrene together, use a 12 or 24 hour cure epoxy, as the 5-minute stuff cures "rubbery" and doesn't sand well (if at all). I like regular J-B Weld unless I need the joint to be clear or semi-invisible for some reason.

I usually use Devcon 5-Minute Epoxy for ALL my gluing chores and it seems to work for me, whether I'm gluing resin, spark plug wires, guitar string, clear plastic, etc.

Thank you for the input guys. I have a resin semi truck hood that has a very slight warp to the sides. I want to straighten them by gluing a piece of styrene to the insides to keep them straight, so there will be very minor stress to keep the resin straight. It sounds like some type of epoxy would be the wisest choice.

CA glue works just fine for joining resin to styrene, and in my experience, will stand quite a bit of stress.  I used to use it for joining resin panels to styrene for making masters for resin casting:  Removing a plastic or resin master body shell from a newly cured RTV mold is just about as much stress as I have ever put on a body shell--almost never experienced a failure of a glue joint doing that.
