May 12, 2006

Patent No. U.S. 7,026,398 B2
Degussa AG has obtained a patent
for a one-component water-free composition
in package form comprised of a
mixture of at least one epoxy resin, at
least one acrylic resin, at least one
acrylic resin monomer, at least one
copolymer based on an acrylic
monomer, at least one copolymer based
on an epoxy monomer, or a mixture
thereof; at least one aminoalkylsilane
and at least one fluoroalkylalkoxysilane,
condensates thereof, or cocondensates
thereof, wherein the molar ratio
of the amino groups of the aminoalkylsilane
to the functional acrylate groups
of the acrylic resin in the case of an
acrylate-containing coating composition
is less than 7:1; optionally at least
one of a silicic ester and an alkyl silicate;
and optionally at least one
organosilane, a mixture of organosilanes,
condensates thereof, or cocondensates
thereof, wherein the fraction of Sibonded
fluoroalkyl functions is from
0.001-5% by weight, based on the composition.
