JB Weld Plastic Bonder, PSA - I'm a fan Options

[DennisV]

I don't know about you, but I've had very limited success in repairing broken plastics. I've tried a lot of variations ranging from household super glue to 2-part speciality plastic products with activators. They rarely withstand any force applied. Yet I keep trying.

This week I happened upon J-B Weld Plastic Bonder. I used it on two different components of the fresh air blower. The black plastic tabs of the housing, which I think is phenolic resin. Also some areas where the fan blades attach to the cage, which I think is probably Nylon. I snapped a plastic spoon to have a pointed tip to apply it with. I actually found it a benefit that it gets tacky pretty quickly.

After 8 hours, both seem quite secure. I had first tried Loctite plastic bond and it failed with the slightest of pressure. We'll see how they do long term, and if the tabs will remain when I try to attach the clips.
