Kansai Paint Patents Multilayer Coating
U.S. 8,247,035 B2
Kansai Paint Co. has been granted a patent for a method for forming a multilayer
coating film by successively conducting
the following steps (1)-( 4): (1) a step of
applying onto a coating object a water-based first coloring paint (A) to form
the first coloring coating film, (2) a step
of applying a water-based second coloring paint (B) on the first coloring coating film as formed in the step (1), to form
the second coloring coating film, ( 3) a
step of applying a clear paint (C) on the
second coloring coating film as formed
in the step (2), to form the clear coating film, and ( 4) a step of simultaneously
baking the first coloring coating film,
second coloring coating film and clear
coating film as formed in the steps (1)-
( 3), wherein the water-based first coloring
paint (A) is comprised of polyester resin
(X) and curing agent (Y), the polyester
resin (X) containing benzene ring and/or
cyclohexane ring in its molecules, their
combined content in the polyester resin
being within a range of 1.0-2.2 mols/kg
(solid resin content); and that the curing agent (Y) is at least one compound
selected from the group consisting of isocyanate group-containing compound (a),
oxazoline group-containing compound
(b), carbodiimide group-containing compound (c), hydrazide group-containing
compound (d) and semicarbazide group-containing compound (e).
Glidden Patents Curable
Water-based Coating
U.S. 8,247,051 B2
The Glidden Company has been granted
a patent for a curable polymeric coating
composition comprised of at least one of a
water dispersion or a solution comprised,
by weight: from approximately 70 percent to less than 100 percent polyetheramine, based on the weight of solids of the
coating composition, the polyetheramine
prepared by contacting one or more of a
diglycidyl ether with a difunctional amine
under conditions sufficient to cause the
amine moieties to react with epoxy moieties to form a polymer backbone having amine linkages, ether linkages and
pendant hydroxyl moieties, and wherein
the diglycidyl ethers is comprised from 5
to 70 mole percent resorcinol diglycidyl
ether; from 1 percent to 30 percent phosphoric acid, based on the weight of solids
of the coating composition; a defoamer;
and wherein the coating composition is
comprised of no aminoplast.
Valspar Patents Heat-Resistant Coating
U.S. 8,247,067 B2
Valspar Sourcing, Inc. has been granted a
coating composition comprised of a resin
system comprised of a polysilazane and
further comprised of a polysiloxane and/
or aromatic hydrocarbon resin; and glass
particles having a softening point below
operating temperature of at least approximately 625° C to no greater than 760° C.
a coefficient of linear thermal expansion
of at least 80× 10− 7 in/in/° C and a dielectric constant of at least 5.
Anti-Reflection, Fingerprint-Resistant Coating
U.S. 8,252,436 B1
Hon Hai Precision Industry Co. has
obtained a patent for a touch screen,
comprised of a substrate; and a coating
attached to a side of the substrate, and
containing titanium dioxide and cadmium selenide in a weight ratio of approximately 3:1, wherein a particle size
of the titanium dioxide in the coating is
2 nanometers and a particle size of the
cadmium selenide in the coating is in the
range from about 2.3 nanometers to approximately 3. 7 nanometers.
Thickener for Paint Systems
U.S. 8,246,738 B2
Agrana Staerke GmbH has been granted
a patent for a method for producing a
dispersion-binder-based paint system,
which is comprised of the step of: admixing a combination of at least one starch
derivative with at least one high-viscosity
cellulose to the paint system as a thickener, the cellulose having a viscosity of
> 50,000 m Pa·s measured by a Brookfield
rotation viscometer as a 2 percent swollen aqueous solution at 5 rpm and 25°
C, wherein the starch derivative is cross-linked and the starch derivative is cold-water-soluble; wherein the system does
not comprise polymers and copolymers
based on acrylic and methacrylic acids as
rheology-imparting agents.
Momentive Patents Coating
Structure
U.S. 8,247,080 B2
Momentive Performance Materials Inc.
has been granted a patent for a coating
structure comprised of an outer coating
comprised of aluminum; and an interlayer disposed between a substrate and
the outer coating, and the interlayer is
comprised of one or more of a rare earth
metal, a transition metal, or a noble metal; wherein the substrate is comprised of
one or more of a metal nitride, a metal
carbide, a metal boride, or a metal oxide,
wherein the metal nitride is comprised of
carbon doped boron nitride.
Valspar Patents Polyester
