Resulting Properties
This adhesive formulation has improved wet tack in which the adhesive joint remains firm immediately after the bond has been established. This adhesive formulation is very flexible even at low temperatures by virtue of its plasticizer components. The adhesive also provides high solids content with lower cost and faster drying times.
The above adhesive formulation is a good laminating adhesive for bonding kraft paper, cardboard, or other paper substrates. 100% fiber tear is high even after the joint has been immersed in water for 24 hours.
