If I needed to bond Polypropylene, I'd choose the 3M Scotch-Weld Plastic Adhesive DP8005 product first. This is based purely on my experience in using 3M products and the fact I had never hear of TAP Plastics before now. That's not to say TAP Plastics doesn't have a good product, it's just I have had great experience with 3M. ________________________________ From: James W.

But here's everything I've gleaned about the three products that various listers and the FAQs suggest (an answer to David's question is number 2): 1. "Plastics are made of polypropylene, not polyethylene. That said, the 2 materials are chemically similar enough that an adhesive that works on one will typically work on the other. Polypropylene (PP) is generally easier to repair than Polyethylene (PE) - but neither is "easy" in the conventional sense." 2. "Checked the TAP Plastics web site to see if the Poly-Weld adhesive works on both materials. They say that it does, so the video shown would be correct. TAP Plastics also stresses the fact that the surfaces to be joined MUST be flame treated and they show you how to do it - which is also correct. The flame treatment would be the same for both PP and PE." Poly-Weld is probably the most difficult to use of the alternatives. I'm not torch-experienced, so I may try one of these first: --"West System G-Flex. It's designed for polyethylene. Although I have no experience with it, the boaters seem to like it, and West is an icon in the composites world. http://www.youtube.com/watch?v=2a5RlcP-4JE>http://www.youtube.com/watch?v=2a5R\lcP-4JE>" --3M Scotchweld Plastic Adhesive DP8005 (I think this is the one recommended in the FAQ). -JWF

I'm asking because they are advertising this as a repair for Polyethylene, which isn't the same as Polypropylene. > > >________________________________ >From: James W.
