3m 77 is a multi-purpose spray adhesive that is "foam friendly" and is ideal for laminating paper drawings to Depron sheets or laminating Depron sheets together.  The nozzel has three spread settings so that you can control the spray pattern. You can also control the amount of "tack" that the adhesive has on the bonded materials e.g if left for several minutes prior to bonding, paper can be peeled easily from Depron at a later stage.
