A gypsum or foam facer is formed by the direct in-line or off-line coating
of a pre-impregnated, fibrous network matting with a secondary binder
system. The pre-impregnated fibrous network is preferably formed of a
randomly oriented wet use chop strand fiber material impregnated with a
modified urea-formaldehyde binder system. The secondary binder system
preferably consists of low glass transition acrylic or
styrene-butadiene-rubber resin filled predominantly with fillers combined
with a plate like reinforcement or fibrous reinforcement. In an
alternative embodiment, a low basis secondary veil is layered onto the
fibrous network matting with or without the secondary binder system to
improve softness and decorative appearance of the formed gypsum board. In
another preferred alternative embodiment, a plurality of high aspect
ratio particles may be introduced to the binder prior to introduction of
an optional secondary binder resin to also improve the softness and
decorative appearance of gypsum board.
