Patent No. U.S. 7,390,559 B2
PPG Industries has been granted
a patent for a multilayer coating system comprised of a first, thermally
cured coating, the first coating being
produced from a first film forming
resin having one or more thermally
curable groups and one or more radiation curable groups; and a second,
radiation cured coating comprised of
a radiation cured resin; wherein at
least some radiation curable groups
in the first coating are bonded to at
least some of the radiation cured
resin of the second coating and the
weight percent of radiation curable
group(s) in the first coating is below
that which is needed to render the
first coating radiation curable.

SHELLBOND PATENTS
METHODS FOR PRODUCING
PROTECTIVE COATINGS
Patent No. U.S. 7,393,558 B2
ShellBond LLC has obtained a
patent for a method of producing a
protective coating on a metal surface. The method is comprised of
heating an animal skeletal material
to a temperature of at least 1000°C
to convert at least part of the calcium carbonate in the skeletal material to calcium oxide and produce a calcined product; contacting at least
part of the calcined product with
water to produce a particulate material containing calcium hydrate; dispersing the particulate material in a
liquid carrier to produce a coating
composition comprising the particulate material; and applying the coating composition to a metal surface to
produce a protective coating thereon.
SURFACE SPECIALTIES ITALY
PATENTS POWDER COATINGS
Patent No. U.S. 7,390,849 B2
Surface Specialties Italy has
obtained a patent for powder coating
compositions which are thermally
and radiation curable. The thermally
and radiation curable powder coatings are comprised of at least one
resin A having epoxy groups and at
least one compound B having acid
and/or acid anhydride groups, characterized in that the resin A has a
specific content of epoxy groups of
from 0.2 mol/kg to 3. 4 mol/kg, and if
compound B has acid groups, that
the compound B has an acid number
of from 150 mg/g to 600 mg/g, and
that at least one of the components A
and B contains olefinically unsaturated groups, the thermal curing
being effected by reaction of the
epoxy groups with the acid and/or
acid anhydride groups. CW
