Storage stable aqueous dispersions of a heat-reactive hydrophilic phenolic
resin (e.g., phenol/formaldehyde) are disclosed. The dispersions comprise
a base resin that is the reaction product of an aromatic alcohol and an
aldehyde, and an etherified resin component selected from the group
consisting of an etherified phenol/aldehyde resin, an etherified
cresol/aldehyde resin, and mixtures thereof. The dispersions further
comprise a protective colloid (e.g., polyvinyl alcohol). The addition of
the etherified resin component in an amount of at least about 20% by
weight of the base resin provides storage stability, but does not
adversely affect the desirable physical and chemical characteristics
(e.g., chemical resistance) of end products made from such dispersions.
Moreover, the dispersions of the present invention can avoid the use of
etherified resin components derived from bisphenol-A and/or xylenols,
which present heath concerns in food coating applications.
