Scotch-Weld Structural Plastic Adhesive DP8005 Black, 45 mL Duo-Pak, 99352

used this to fix a growing crack/break in a large polypropylene plastic panel in my car's trunk. bonded extremely well. this part of the panel has the hinge for the trunk cover so it takes extra stress. not a shred of issues after letting it set for 48 hours expensive but still much cheaper than taking to the shop or replacing the plastic panel.

Using it to glue endcap to NDS channel drain. NDS said the plastic is HDPE, high density polyethylene, and recommended contact cement. I tried contact contact cement and PVC and neither worked. Contact cement was tacky but definitely not strong. PVC did not adhere and flaked off. This glue has 3 min work time during which the glue remains pliable. Glue mixture has consistency of yellow mustard and will fill 1/16" - 1/8" gap. It dries after 3-4 hours and is very strong. I can't pull it apart! I wiped contacting surfaces clean before application but no further treatment beyond that (e.g., sanding, flame). The only downside is that it needs a special applicator gun, which includes the necessary 10:1 pistons to get the right mix. You also need a 10:1 nozzle. Listen to what the other reviewer said. I bought the applicator gun (which 10:1 and 1:1 pistons), nozzle, and glue from amazon.

I have a John Deere tractor and it was leaking diesel from a crack in the plastic tank. I couldn’t fill it over a quarter tank without it leaking. The dealer wanted about $1500 to replace the tank and said it was unrepairable. I tried some other products that failed to work and was about to give up. Then I saw this and gave it a try since it is made for the special type of plastic these fuel tanks are made of. It is still working after 2 months of use. It was very easy to use and requires no special prep, but the glue gun I had to buy to apply it was stupidly expensive for what it is. Anyway, the $130 I spent for both was still far better than replacing the tank. Even if the leak returns I have plenty left to keep repairing it.

Not sure what this is for, didn’t work on my Delrin plastic, I returned it for a full refund, but it cost me money by ruining my parts

I’ve used this twice to repair broken plastic parts on vehicles. It leaves a messy bead, but makes a strong bond where epoxies simply won’t hold.

Why did you pick this product vs others?: The adhesive is advertised to work specifically for automotive plastics. I was doubtful, as every other adhesive I have tried did not work very well, if it worked at all, but this stuff works! For the price, it better have, as it is really expensive. Finding the right dispenser was a chore, but I finally found one on eBay that was not more expensive than the adhesive itself.

Works very well for bonding various types of automotive plastic. Read the tech sheet from 3m and follow the instructions and it will perform well.

If you need to bond HDPE or other plastics with extremely low surface energy, this is the product you need. I used it to bond a large HDPE sheet to a frame for an outdoor grill prep station. That was 2 years ago and it's still holding strong. I tried other adhesives and nothing worked until I found this. You'll need a 10:1 epoxy gun and mixing applicators, so it's not cheap. But it's the only thing I've found to work.

El pegamento tiene una capacidad de resistencia al pegado que no cumple y con la temperatura se fractura y deja de ser funcional
