Title: What type of plastic is used for the top box
Post by: Bassaw on March 14, 2025, 01:22:26 PM
Hi all, I need to glue a small bracket to the inside of the top box. I was about to use Gorilla Epoxy but noticed that it's not recommended for either polyethylene or polypropylene plastics. One of my box retaining strap holder broke and I've tried several different ways to fix something that will hold without any luck so far. So I've decided to fashion a small section of metal strip which will need to be secured to the inside of the box. Just not sure what type of plastic Honda used. Any constructive advise will be appreciated.  :think1

Plastic weld would be most successful I think

Best guess is ABS. That's what most fairings etc are made from

It's probably ABS but even if it's not, this glue supposedly works on polyethylene, polypropylene as well as ABS...  :think1

Would be worthwhile finding a donor box and then try the good old fashioned trial and error method of determining the best bonding agent.

The top box is made of PP-15GF, which is Poly-Propylene with a 15% glass fibre fill. The lid is ABS. This is from the codes inside the box with the manufacturing date etc.

Thanks everyone that is most helpful. I'm going to check out Gluesaustralia for compatible type. I'll advise how I eventually get on. Cheers Bas

Is it just the screw that's ripped out of the plastic or has it actually broken a piece out?

That superglue I linked to is available from Bunnings...

ruSTynutz Thanks for your help. Unfortunately it's the plastic lid base that has snapped off. I will try another Bunnings as my local one does not stock this Selley's product. Cheers Bas

I have repaired the Top Box and with any luck should serve me for a long time to come. The plastic lug that secures the box lid snapped off and I used Selleys All Plastic ( thanks to ruSTynutz) and Gorilla Epoxy glue to secure the modified metal bracket and plastic cover.   If anyone would like to know exactly how I fixed this please let me know.

I'll bite.  Is the thin red wire a safety strap or (for some reason) an earth tie?
It can't be for an auxiliary tail light unless there's a black wire somewhere else.

Correct Brookester - The wire in the picture is twin Red/Black running to the top box brake light

I used 2mm stainless steel cable inserted through some flexible plastic tubing...

Hey!  Enough with the mockery of the elderly!   :p

I used light chains, one each side.  The tubing is there to direct the chain inside the box as the lid is closed.  I have the same set up on my V-Strom top box.
