I have been looking for this for over 20 years and I finally found it.
Locktite 3035 2-part adhesive for Polyethylene and Polypropylene
http://www.henkelna.com/3035http://www.youtube.com/watch?v=RpxvsVEA ... ure=relmfu:
2-4 minute setup time
10-15 fixture time
no priming or chemical cleaning of parts needed. Comes in a twin tube design like epoxy with a mixing stick. It is not yet at the distributors but should be available at McMaster Carr, Grainger, Fastenal and others.

I saw it first hand at the design and engineering show today in Chicago.
