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!

This stuff is dangerous: now I can glue just about anything! Would highly recommend wearing disposable gloves when using this though.
