Application No. 08/196,819
60 weight percent of the nonaqueous components of the chemical
treatment, and
b) vinyl acetate organosilane copolymers, where the
amount of organosilane in the copolymer does not exceed about
1 weight percent of the copolymer,
wherein the polyvinylacetate polymeric material is
present to give a ratio of the two film forming polymers
ranging from 1:99 to 99:1, where the polyvinylacetate
polymeric material results in the glass fibers with the dried
residue having PEG wet-out values of about 8 to about 16 at 95
percent wet-out and about 4 to about 9.7 at about 100 percent
wet-out in uncatalyzed resin, and where the amount of the
second film forming polymer comprises the balance of the film
forming polymer for the aqueous chemical treatment and where
the two film forming polymers constitute the total amount of
the film forming polymers in the treatment and where the total
amount of the film forming polymers that are present in the
chemical treatment is at least 40 weight percent of the
nonaqueous components, and where the lubricant is present in
an amount in the range of about 0.05 to about 0.5 weight
percent of the aqueous treating composition.
