Bonding ABS to GRP

[tracem]

I have to fix a smallish (280x200mm <0.5kg) ABS enclosure to the rear of a GRP panel.

I am aware, thanks to Ed Clymer, that this is not recommended.

Is there a suitable non-porous material I could use as a gasket, that I could interpose between them, that would bond well to both?
What adhesive(s)/etchant(s) might I use?

Thanks in advance.

What matrix polymer is the GRP?

Thanks for your reply.
It's a polyester resin of some kind.
The materials data-sheet is in Italian, so I will have to contact the manufacturer (on Monday) to find out exactly.
Thanks again.

I see no issue. Try epoxy.

I think from memory, polyester resins are a good adhesive for ABS

Some solvent adhesives do solvent stress crack ABS so testing should be carried out.

RTV silicone will bond nicely to both of those substrates, and absorb any difference in thermal expansion,
PROVIDED
that the mold release is removed from both substrates, e.g. by abrasion.

Use masking tape to fixture it.
When the tape has rotted enough to fall off, it won't be needed.
