Application No. 08/196,819
composition comprising, inter alia, two aqueous soluble,
dispersible, or emulsifiable film forming polymers wherein the
first polymer is either a bisphenol A polyester or an
esterified epoxy resin and the second polymer is a
polyvinylacetate homopolymer or a copolymer of vinyl acetate
and an organosilane (appealed claim 1) or more broadly, a
polyvinylacetate copolymer (appealed claim 23). The
vinylacetate polymer functions to produce glass fibers with a
dried residue having "PEG wet-out values of about 8 to about
16 at 95% wet-out and about 4 to about 9.7 at about 100% wet-
out in uncatalyzed resin" (appealed claims 1 and 23).
Appellants characterize the claimed treated glass fibers as
having "optimum wet-out" in thermosetting matrix polymers used
to produce glass fiber reinforced plastic (FRP) panels on non-
linear conveyors (brief, page 4). According to appellants'
specification at page 4, the term "wet-out" means that the
matrix polymer encapsulates the glass fibers and very little,
if any, bare glass is visible throughout the cured-fiber
reinforced polymeric material. Thus, according to appellants,
"wet-out" during production of a glass fiber reinforced
polymeric material is a measure of the apparent intimacy of
