Bonding polypropylene sheet
Has anyone tried using PU adhesive on the black polypropylene trim sheet that MK supplies for covering the transmission tunnel. I want to bond a piece
onto my R1 airbox so I can use it upside down (lower profile). The 'Direct Plastics' website suggests that it is very difficult to bond bu
I'm sure I've head of people on here bonding the sheets to their chassis. If it's not going to be very strong I'll have to remake
it in ally.

it won't be very strong and the only way to get it to stick it roughing up the polypropylene a lot to get a good key. personally i'd go
with the ally

Why not drill and rivet it as well? Use sealed rivets or fill them afterwards. That and a bead of PU should do it!

Yeah i would go for a mechanical joint, its s slippy bugger.
- Rough it up a bit, pop rivets and a bead of pu to seal.

What size is the piece of poly that you want to bond, I may have an offcut of carbon fibre that you can have for free that will bond with pu well...

As i understand it he's trying to bond the two items in the photo.
- The cut out plate, the the PP air box.
- Simply using the panels as and example of another place pp is used.
However i would say the comparison is poor as it one thing to bond a non load bearing sheet with high contract area, and quite another to make a
structural and airtight join! Particularly as the contact patch between two looks to be not amazing.

The panel is PP, not sure what the airbox is made of. I think I'll try a few rivets with the PU to help secure it & if that doesn't
work I'll get some 6mm PVC sheet & try that.

Im only reading it off the photo, but it does appear to say PP on it...? Burn test?

I joined my airbox with resin and matting, it isn't on the road but it hasn't fallen apart in two years.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
