Hi

At the Dupon Tyvek FAQ

http://www.tyvek.com/na/industrialpack/english/5techtips/#glue

we can read the following:

Solvent-based single-component polyurethane adhesives provide optimum
adhesion (lap and shear), flexibility and water-resistance for
adhering TyvekŽ to itself and a variety of substrates.

But what is a Solvent-based single-component polyurethane adhesive,
and where i can find this glue ?

Thanks in advance for your collaboration and excuse my English.

I would run down to my local hardware store and buy some Elmer's
ProBond Polyurethane Glue. It looks like what you want...

Here is Elmer's web site with a link to the MSDS on it.

Please report back you findings, as we all want to learn, that is why
we are here.

Single-component implies solvent-based because you don't mix two tubes
together (resin & hardener for example). It relies on a highly volatile
solvent to evaporate off and leave the "glue" behind to dry.

So any single tube of polyurethane glue that smells really bad will do.
Canadian Tire will carry such an animal.

Bon chance!

Gillis,
I use a one part polyurethane called Gorilla Glue. It tends to foam on
curing, and stains your hands, but is a great epoxy alternative. On Tyvek,
3M 77 spray adhesive works well for me, especiall on larger areas.
