Bought this to bind Rubber and 3D printed plastic trim bezel that holds a cell phone in place over a phone charger in the center console lid. Worked like a charm! This stuff is SOLID to use on Plastic and Rubber.

I have used this product to repair plastic, rubber and ceramics. It works quickly and creates an amazingly strong bond. Though the bottle is small, it takes very little product to create the bond.

This is my second bottle of the "3M" PR40. I have been surprised at how well it works on rubber and hard plastics. I have not tried it on HDPE but do not expect it would work well. I have repaired inter tubes, butted "not lapped" together inter tube material to make large rubber band, glued hard plastic parts back together, and even cut/spliced a used serpentine belt as a replacement belt on a old south bend metal lathe. It also seems to work on what I call siliconized rubber but have not done a durability test on that other than giving it a few yanks. It only takes a thin even amount on one surface with Good pressure to work - I always keep my bottle upright during storage and never had the tip plug. If lap jointed it will always break elsewhere on rubber and not the joint. OBTW I always clean the rubber with brake cleaner and wipe dry.

This adhesive worked great for my project which was to bond some 3D printed (PLA) items to polyethylene (HDPE). After 24 hours of curing the two items were bonded together as if they were one. There was a lot of surface area for the connection that I was bonding so perhaps my situation was optimal for this product but I couldn't be happier with the result. There's not a lot of instructions included, so it might be helpful to know how I used the product:- I started with both surfaces to be bonded in a horizontal position. The adhesive (and the primer are very thin and runny and this is the only way to minimize the mess.- I masked off the non-bonding areas with blue painters tape to further reduce mess.- I first primed the pieces by brushing the entire (cleaned) area for be bonded with acetone. Acetone is cheap and I had some (from Home Depot) so I decided to try it as an alternative to the expensive but official 3M primer.- I applied a thin layer of adhesive to the HDPE side, spreading it about a bit with a wooden stir stick.- I joined the pieces, clamped them together and carefully wiped away the excess with a paper towel. Note that the bonding is not immediate. Out of an abundance of caution I left the clamps on for 24 hours.Maybe another process would work as well, but that worked great for me. You end up using a very small amount of adhesive so the little bottle goes farther than you might think. To be honest I had serious doubts that anything would work to bond HDPE, and was amazed at how well it ended up working. Good luck!

After a lot of research I bought this glue to repair some tennis shoe soles that had started to come loose. I looked at lots of glues - instant, contact, two-part, etc., and eventually landed on this one. It is one of the more expensive adhesives, and it comes in a very plain, industrial-looking plastic container, no animals, colors or pretty pictures on the bottle, and in a plain cellophane wrap, but does it work?You bet it does. I can't quite believe the level of bond I got on rubber to rubber, it's amazing. There is absolutely no give, no sign of the edge coming loose again, it's very solid. At the price, I can see why you'd have reservations, so go ahead buy a cheaper one and be frustrated when it's not quite as good as you need. Then buy this one. I've been there. I write some reviews but not many, however this product got my attention and if you want something that works, get your wallet out, but this works.One more important "health and safety" thing. The small-print is *small* - it's really tiny, I used a loupe to read it. But definitely read it. My inner five year old came out and I smelled the glue while it was wet. REALLY BAD IDEA. Don't do that. It doesn't just smell bad, it smells dangerous. It made me physically recoil and it took a while for the weird feeling in my nose to go away, so don't smell it, and keep the product locked away from the wee ones. That's all. Great glue, easily worth the money.
