3M 21200300882 4693H High Performance Industrial Plastic Adhesive, Amber, 5 Ounce

I use this product because it was recommended to use when installing Harley Davidson saddle bag liner supports. The glue did a excellent job.

This is my second tube of this glue. I used both tubes for gluing an IRIS plastic labeled box to other plastic materials. One time to glue the IRIS box to Plexiglas. In all applications that I used this glue, it worked perfectly. It did require clamping to hold each item in place while curing. Minimum clamp time was 30 minutes outdoors at 80+ degrees F. Additionally, I am using this glue in wet applications with up to 3 months without fail.To test this glue's strength in a case where pressure or stress is applied, I applied the glue to two ends of a broken piece of plastic. I waited 24 hours. The two plastic pieces came apart easily when twisted. I would not use this product for joining two ends together if there will be stress applied. This glue dries maintaining flexibility.My next project with this glue will be to stop a leak in my vans radiator reservoir. Hopefully, I will remember to update this review with the results.

Does indeed adhere well to "low surface energy plastics" such as polyethylene, but has very long setting time which makes it necessary to clamp or otherwise mechanically fasten together pieces for several hours to over a day. Not good for fast repairs, therefore, which is what I needed. If you have the time, though, it will fasten together slippery plastic materials that few other adhesives can.

Good product

Holds plastics together well, but not much better than most contact adhesives. Take many hours to harden.
