ABSTRACT:
A pressure sensitive adhesive is disclosed that is tack-free to the touch, but forms a permanent bond under moderate pressure. The pressure sensitive adhesive contains a tacky adhesive latex, a non-tacky latex or polymer, and an inert filler. The tacky adhesive latex provides the sealing properties, the non-tacky latex or polymer provides blocking properties and the filler absorbs oil that may adversely affect the sealing properties. The adhesive is tack-free to the touch yet becomes activated to form a permanent bond under moderate sealing pressure.
