PPG patents electrodepositable coating
Patent No. U.S. 7,497,935 B2
PPG Industries has been granted
a patent for a process for coating an
electroconductive substrate comprised of electrophoretically depositing on the substrate a curable electrodepositable coating composition to
form an electrodeposited coating
over at least a portion of the substrate. The electrodepositable coating composition is comprised of a
resinous phase dispersed in an aqueous medium, the resinous phase is
comprised of one or more ungelled,
active hydrogen-containing ionic salt
group-containing resins, which are
electrodepositable on an electrode;
one or more curing agents; one or
more metal deactivators; and curing
the coated substrate.
ation to actinic radiation to give at least
one clearcoat cured with actinic radiation, and subjecting the at least one
primer film, and the at least one pigmented film, to joint thermal curing.
soluble polymer solution comprised
of from 0.5-5% solid level characterized in that the viscosity of the aqueous superabsorbent polymer paste
will be from 1000 mPa·s and to
approximately 35,000 mPa·s.
BASF PATENTS MULTICOAT/
COLOR EFFECT PAINT
Patent No. U.S. 7,479,308 B2
BASF Coatings AG has received a
patent for a process for producing mul-ticoat color and/or effect paint systems
comprised of at least one primer, at
least one color and/or effect basecoat,
and at least one clearcoat comprised of
applying at least one primer curable
thermally and with actinic radiation to
a substrate to give at least one primer
film, exposing the at least one primer
film to actinic radiation to give at least
one partially cured primer film which
can still be thermally cured, applying at
least one pigmented coating material
curable thermally to the outer surface
of the partially cured at least one
primer film to give at least one pigmented film which can still be cured
thermally applying at least one
clearcoat material curable with actinic
radiation to the outer surface of the at
least one pigmented film to give at least
one clearcoat film curable with actinic
radiation, exposing the at least one
clearcoat film curable with actinic radi-
HENKEL PATENTS
REACTIVE HOT MELT ADHESIVES
Patent No. U.S. 7,645,831 B2
Henkel AG & Co. has obtained a
patent for a moisture curable hot melt
adhesive composition prepared by
reacting a polyisocyanate with a mixture comprised of a urethane diol and
a polyether polyol or polyester diol or
both. The urethane diol being the reaction product of a cyclic carbonate and a
compound containing an amino group
and a further group selected from the
group consisting of amino groups and
hydroxyl groups, which composition, in
the presence of moisture, cures to an
irreversible solid form.
CLARIANT PATENTS
AZO PIGMENT PREPARATION
Patent No. U.S. 7,645,336 B2
Clariant has received a patent for
an azo pigment formulation comprised
of 4, 4’-diaminodicyclohexyl-methane
wherein a fraction of trans,trans-iso-mer is at least 25% based on a total
amount of 4, 4’-diaminodicyclohexyl-
methane.
AGION TECHNOLOGIES
PATENTS COLOR STABLE
ANTIMICROBIAL COATINGS
Patent No. U.S. 7,645,824 B2
Agion Technologies, Inc. has received
a patent for a substantially color stable
antimicrobial coating system comprised
of an epoxy resin-based or wax-based
coating composition and from approximately 1-30% weight based on the total
solids content of the coating composition of an antimicrobial metal-ion containing, ion-exchange type inorganic
antimicrobial agent the antimicrobial
agent is comprised of from 0.1-25%
weight silver ions and 0.1-25% weight
copper ions, based on the weight of the
antimicrobial agent, and wherein the
weight ratio of the silver ions to the copper ions is from 1: 10 to 10:1.
SUPERABSORBENT POLYMER
AQUEOUS PASTE AND COATING
Patent No. U.S. 7,488,541 B2
Evonik Stockhausen, Inc. has
obtained a patent for a coated substrate comprised of a substrate material, an aqueous superabsorbent
polymer paste comprised of a blend
of from approximately 1-5% weight
of superabsorbent polymer particles
having a particle size distribution in
the range of greater 150 microns to
smaller than 850 microns, and from
95-99% weight of an aqueous water-
POWDER COATING COMPOSITION
Patent No. U.S. 7,485,674 B2
Toyo Aluminum Kabushiki Kaisha
has obtained a patent for a powder coating composition comprised of powder
coating particle including thermosetting resin powder, an adhesive binder,
and a flake pigment bound to a surface
of the thermosetting resin powder by
means of the binder; wherein the powder coating particle has an average particle size of at most 100 μm based on
D50 conversion, a bonding ratio
between the thermosetting resin powder and the flake pigment is in a range
from 90-100%, and the adhesive binder
is of at least one selected from the group
consisting of terpene resins, terpene/phenol resins, terpene hydrogenated resins, and terpene/phenol
hydrogenated resins. CW
