Water-based adhesive compositions are improved by the incorporation of
hollow polymeric microspheres having outer surfaces coated with one or
more barrier materials such as calcium carbonate particles. The adhesive
compositions exhibit enhanced rheology, sprayability, drying time, tack
and storage stability as compared to analogous adhesives that are not
modified with coated hollow polymeric microspheres. Such compositions are
useful as both contact adhesives as well as wet bonding one-way
adhesives.
