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

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.

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

I used this glue when repairing iPods. One of the biggest problems repairing iPods is getting the screen to stay down. I've tried every type of double sided adhesive tape on the market only to have the screen separate from the body of the iPod time and time again. Out of desperation I tried this glue. I needed a glue that would not damage components, could be applied very thinly, would hold the screen in place yet allow me to remove the screen later if needed. This glue did all of those things. It will definitely be stocked in my repair shop from now on.

I used this product to glue together a broken poly wood (recycled plastic) outdoor adirondack rocking chair. One of the rocker legs had cracked and broke apart in 2 pieces. After following the tube directions, and waiting 2 days to fully dry, I could take the broken piece I glued and easily pull them apart, leaving stringy, rubbery strands of glue on each end. The glue seal is very similar to rubber cement, in fact, I can't tell the difference. I was expecting more of an epoxy type bond, but this isn't it. I ended up screwing in brackets to keep the 2 pieces of poly wood together.

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.
