Glueing Volvo plastics (broken bumper clips for ex)...

[AylmerQc]

What glue do you prefer and have had success with to bond polypropylene, which is the type of plastic used for bumpers?
I've found a few brand names such as glues made by LocTite, 3M,JB Weld and Permatex.
I'll be heading out later to see what I can find but would appreciate some recommendations...

A sheet of ABS abs plastic or zip tie melted do wonders depending on the strength needed. Sometimes the repair is stronger than the plastic.
.
Hacksaw a small strip and melt into plastic with a soldering iron. Reinforce as needed with mesh or paper clip depending on the repair.

Where do you get abs sheets of plastic? Do you melt it (or the zip tie) with a heat gun or soldering iron?

Polypropolyene requires a primer before the glue. I have used Loctite 681925 with some success.

Best bet is to get the same plastic part from the junkyard, it is almost the only way to ensure you get the correct plastic that will bond well. I think the zip-tie solution will be hit and miss.

Look at the videos for how to melt it and do "plastic welding."

I bought a cheap Harbor Freight plastic welder (mostly just blows very hot air) to repair a crack in a plastic fuel tank. As said above, the correct plastic is critical - look for the manufacturing codes molded into the part. And it was a messy process - not something for an exposed finish surface.

There are some professional 3M products body shops use for bumper repairs.

Oh sorry, an inexpensive generic soldering iron has worked well. Most come with several tips to choose from.

There are specialty soldering irons for mending plastic. As several members have stated use the same type of plastic. I'm pretty sure the ABS will work with most the plastics on our cars however.
