Polypropylene glue/adhesive question

[Halfhitch]

I am wondering if anyone has had any luck glueing polypropylene. If so, what product did you use?

 

[seasick]

are you referring to HDPE, high Density Polyethelene or do you really mean polyprpylene? Starboard is a HDPE product
Regardless, neither is easy to glue. I have seen videos of some success for starboard that uses a special adhesive and a flame treatment of the joints before glueing. I think a Ca type super glue was used.

I have used the 2 part

Loctite Plastic Bonding System on polyethylene. It claims to work with polypropylene too. ​

Not starboard but the white/translucent polypropylene. I tried J-B Weld Plastic Bonder and no luck. I'll look into the stuff family affair recommended.

I used that stuff on a large plastic garbage bin but it didn't hold up. It originally seemed OK but under stress it failed.

For the record, I made no claims to its performance, other than it did glue 2 parts together.

So yer sayin' I shouldn't use it to glue my harness to the cross canyon zip-line?

Depends on what kind of outcome you're looking for!
